I had the main belt shaft bearing go on mine. Changed the 2 bearing, 6001 and 6002. They are cheap bearing from manufacturer and that is why it does not last. I put in new SKF bearings. The part that you were saying did not turn when you rotated might of been ok. Beside your bearing that was damage was a flat plate (between the bearings) and when you pull on the levers connected on the plate it rotates and separate the bearing, when you do and rotate the shaft the 2 wheel gears rotate, it is a clutch.. I am positive if you would of changed the bearings you could save the transmission. In a shop, this is not feasible because of labor costs, but if you do it yourself only bearing cost, silicon sealant and gear oil. I did mine.
Great video Don. I just had a customer with a Craftsman snowblower that had the same defective transmission. He decided to scrap the snowblower and sell it for parts. The snowblower was only 4 years old and bought from Sears.
I've been looking at many of your videos to fix my snowblower and they helped me a lot. Thanks for exposing this type of transmission. I think i will do without this type of transmission when i buy a new snowblower.....
I decided to take the transmission apart after watching your video, it wasn't the easiest thing to do. I did find out that it can be repaired, the bearing that failed is a 6002.
JLD Enterprises Small Engine Repair I have opened up my brothers transmission (exactly like this whit the same bearing problem) and I just wonder how you did manage to dismount that axle were the faulty bearing is on? Did you have to loosen all 3 axles? everything is kind of loose but still noting will come out and whit plastic pieces everywhere the risk of breaking more is big.
+Gabriele Olivieri Tis a snowblower, used on a cold day, and the trans wouldn't produce much heat anyway. Besides, the Metal bearing failed because it had a load on it's side which it is not designed for. I think the nylon gears would have gave 10 years of service, but that bearing was designed to fail fast I am almost certain.
+efilnikufecin2004 These are probably thrust bearings which are designed for a side load, but as you state, a bearing in a proper oil bath should remain well below the temperature needed to cause damage. The single biggest issue for me is the companies that produce these transmissions have no provision in place to sell these parts. They may order 5000 gears at a time but won't sell them to the consumer so if one gear fails you can't fix it even though the part is readily available.
will that cog come off next to the bad bearing? maybe something wrong with that cog but if it's only the bearing, you might be able to match that up at some bearing and seal distributor?? just wondering.
A transmission at all in a snowblower is the problem, it isn’t necessary in my opinion, I like the simple ones that just have the drive disk and friction wheel, when the rubber wears out you just replace the wheel, no gears and extra crap that can break.
You can buy bearings there’ll be a number on the bearing and then they would match it to the race at a transmission shop. I would imagine or a bearing service place
Regardless of what material is used for the gears; plastic, aluminum, steel, brass, etc. it seems needlessly complex for a snowblower transmission. The old friction plate/disc drives are simpler and more reliable. I have a a 25 year old Ariens that runs like new. The only maintenance it required was a carb rebuild and periodic lubrication.
Friction disc is simple, but they dont tolerate heave usage. Every high-end snowblower has a hydrostat. Same with lawnmovers. A GOOD quality hydrostat lasts forever, and u never need to service them at all. The one in this video is garbage.
Hi Don, Thank god I found you. I'm going crazy trying to figure out why it is so difficult to move my Ariens snow blower model 921045 forward and reverse when the machine is not running. I took the pan off flipped it on it's nose and the only thing I can image is causing the problem is there is no position I can shift the drive speed selector into that will lift the friction wheel off the friction disc. Is there a position that allows the friction wheel to not be in contact wit the friction disc? This machine has the auto turn. I would appreciate any advice. Thank you, Kevin
All bearings can be replaced. all you need is the parts number off of the bearing. There are plenty of places on-line that sell all size and shape of bearings. If the bearing has no part number marked on it then you will have to use a caliper to measure the old one.
Are all new snowblowers equipped with these plastic transmissions or are the friction wheel types still available?. I have a 25 yr old Dynamark Plus snowblower that has the friction wheel type and it has given me excellent service over the years.
I would think they would use steel gears but I guess it might cost a small fortune to buy a snow-blower. Thanks for showing this video, very well done.
I have what I think is the same trans in my Simplicity Snow thrower and the gears are almost impossible to change. I dropped the pan under the machine and there is a lot of oil on the pan so I believe the trans is leaking, What I want to know is how much of an effort is it to remove and replace the trans from the machine? I can't find that info anywhere.
I came across one of those about a month ago, same issue. It is now early 2018 and they are still a replacement only. I have found the parts list but the only available parts is the mechanism on the outside of the case, nothing internal.
I am sorry to say ! I have a snowblower typ Stiga Snow Flake year 2011, and I had the same problem. Had to replace the gearbox !! I wonder how long this will last ?
Maybe the wheels got jam pushing into a pack snow bank and unlike the friction disc type of transmission the transmission bearing got strip while still being engaged. I watch this video a few times just trying to figure out how the speed selection gears work with this transmission when it was a working properly. Great video! Thank you.
Donyboy My 30'' Snapper SB ..Series 5, Model 10305E, Tecumseh Engine HMSK100, Bougth 1995 new. (I'm not green working on my yard machines) but am perplexed on this. Fall of 2015 Changed oil, plug, added little marvel mystery oil to gas, greased all points.

And it was running so great in the fall....I'm so mad at this...can you give me some suggestions ?
It looks similar to the one I'm working on now except the gears are metal on the one I have. The bearing and bushing get jammed into the worm wheel with the metal lever and friction causes it to lock the shaft which operates the transmission. There didn't seem to be much oil in that one which could have caused the bearing failure. It took me three days to locate the manufacturer of the bronze worm wheel on the transmission I have but it's easily repairable if they sell me the part. I can't tell from here but I'm guessing replacing that bearing on your transmission will get it working again.
Hi, It's been 6 years from your comment, but did you manage to find that worm gear? I have replaced those failed bearings about 6 years ago and now that plastic worm gear failed and can't find the replacement anywhere 😬

+donyboy73 I think that's how we all started? I got one of the first digital watches for Christmas when I was around 8-9. Poor thing only lasted 2 mo's. I had to pull it apart to see what made it tick!

I'm sure you could buy an off the shelf bearing for it elsewhere if you were desperate. thebearingshop UK has helped me out here at home. not sure what the Canadian equivalent would be though.
My 10 hp Craftsman from the mid 80's is still going strong (touch wood). No reason to switch from the old friction plate to this type of transmission. Just brutal that these seem to fail so quickly and are so expensive to replace.
I think I would avoid buying any snowblower with this type of transmission. Complex, apparently unreliable, can't be serviced, and expensive to replace. I'll stick to the simple and reliable friction plate transmission.
Agree... Any component that relies heavily on nylon gears is simply a problem waiting to happen. Looks like it was designed from the ground up to be a frequent & expensive Failure.
@@taftr Canadiana put this crap in their snowblowers. Cannot try to shift if the machine is not running. Know folks who had these and they were broken within an hour of use.
Another attempt at over Engineering a simple process The old Transmissions very simple in design worked for many years with no failure at all these are in almost all newer Sears machines JUNK
I used this video to repair mine, same thing happened part # Nsk 6002cm 802. Definitely a poor design ,I would recommend replacing that bearing with a bushing of the exact same size. That’s what I’m doing if it happens again
As one of the other commenters remarked, it is a poor design and the bearing failed because they are using it to apply side force to the cone clutches. I'm going to see if I can get a more heavy-duty bearing to replace it with.
the bearings are common 6002....i recommend buying the best you can find.....its an awful design that applies side pressure to that (those) bearing(s) to engage the cone clutches (which are inside that plastic gear next to the bearings and driven by the worm input)...they used a radial bearing in an application that requires thrust type bearing
does the bearing have any #'s on it? likely an industry std size. you could check mcmastercarr for one of the same size and design. easy to navigate website if youve never checked it out. gotten me by repairing just the bearings on a vacuum motor once when thats all that was wrong.
I have a Briggs and Stratton Brute blower with the plastic transmission. I have had it in for service 3 times because there isn't any difference in speed in 1st or 6th, it is all slow. Sometimes i have had to actually push or pull it back to my shed. The Briggs repair never said any thing to me about the transmission being an orphan. About 3 weeks ago Briggs approved a new transmission exchange. I have used it twice and there isn't any improvement in the way it works. Briggs refuses to admit that there is a problem with the units. BEWARE
I’m having this same issue. R1 doesn’t work at all and R2 is as slow as R1 or worse. Same forward speed with all 6 speeds. Occasionally it will shift properly. I’ve used this blower maybe 10 times. Since I’ve owned it. Any insight on this anyone?
400.00 dollars for a junky plastic trans, Dang! I believe i would've tried to find a good used snow blower that did not have that type of trans in it for that. GOOD INFO.
thanks for this video, I really appreciate it so very much. I'm sure I will come up against one of those transmissions in my own shop sooner or later. People may try not to abuse the transmission if they know it's all plastic ;-)
Wow. What an over-complicated mess of cheap guts! Makes me appreciate my life long choice of Ariens blowers even more! Simple, robust, durable, life long.
at 3:17 the plastic gear right above your fingers is connected to the input shaft but is not driving the shaft it is on. Likely related to the misalignment of the shift fork which is caused by the bearing failure.. At 3:49 the gear you will point at has nothing wrong, it is not engaged. As for the failed bearing, it failed because it has a load on it in a way that bearings of that type are not meant to handle (pressing on the side of the bearing. This will be the common failure point of these transmissions. If you were to contact any bearing supplier and show them that, they will agree. I would not pay $400 for a replacement transmission, I would replace the snowblower because this will happen again unless they change the design. This is an obvious defect in workmanship, and likely an intended flaw (planned obsolescence).
not trying to say that i'd rather have plastic gears rather then metal cause obviously metal is far superior however i have one of these units and have had one for around 4 years now and all the plastic parts are just fine.. only issue's i've had are vibration related.. gotta keep on top of torquing all the screws/bolts regularly however that being said the flywheel that moves to change your speed has given me problems to the extent of having to lube it up with some good quality grease cause it has a tendency to stick in gear i'm assuming because the flywheel just sticks and your left with your rig only being able use 1st gear. For a guy that has a super long driveway that is annoying.. Love the video though i was tempted to take the transmission apart and now i'm glad i didn't heh.
My friction wheel drive lasted 12 years with simple maintenance, 100$ 2 belts and friction wheel, good to go for another 12 years. Suprised to see plastic junk like this in a snowblower.
What a peace of junk! Plastic, plastic and more plastic and what fails a steel bearing :) Great video I am also interested in "new" design of parts like this what is inside and how is made.
I would think NOT to purchase a Snow-Blower that has this transmission, instead to get a snow-blower with manual mechanical rubber friction wheel for shifting. What was that brand snow-blower with the particular transmission that cost over $400? Let us know please.
I love it when someone says I've never worked on one if these before , and the guy looks at you like hes horrified. Come on, techs can go back to"basic training 101" theory and use that. You did pay attention in tech school right? When something doesn't have a manual, you gotta go back to theory for your diagnosis. My other favorite is to say "let's see what happens " 😂😂 That makes eyes go big too!!
+donyboy73 Of course not. That is what makes it fun to take apart mystery boxes that any service performed on, is shunned by the manufacturer 😂 It's kind of sad everything is going toward an assembly with no parts available.
Great informative video on exactly the same transmission l,m having a problem with. Who designes these machines ?.lts very frustrating trying to access any cables etc.We just had 0ver a metre of snow and my machine,s tranny went just as l was finishing up.they should stick with the old friction wheel Keep it simple stupid.Thank for the great videos.
that's a shame, what happened to the old school transmissions which where aluminum or steel, they must not have used high quality bearings, that's the quality of MTD & Murray
If you buy a snow thrower with an MTD transmission who's vision is delivering the best consumer experience then this is what you can expect when it breaks . [quote] this part never been available for the aftermarket. Unfortunately only the complete transmission is available.[/quote]Stick with a friction wheel!
Hi Dony, I buy used snowblowers quite often, which snowblower did this transmission come out of. I would like to know, so I won't buy it in the future thanks.
+-Doug - Briggs and Stratton now owns Murray, but Murray has been at the lower end of equipment. Craftsman no longer uses AYP, the lawnmower decks for instance are made in China now and have plastic parts. MTD used to make quality products as well. Now there products are also low quality.
I had a Sears snow blower in 2013 with this transmission and it only lasted three months before it broke. Sears Just kept replacing the transmission till it was out of warranty. Had to junk it and buy a different brand of snow blower. Never buy another Sears snow blower.
The bearing was running in oil too, must have been faulty. Did you try to substitute a bearing from something else? I once had 2 needle bearings go in the transmission of an MTD and the parts supply store said I had to buy the whole thing..... over $200. My buddy down at the auto parts store had a bearing out of the transmission of a dodge car that fit perfectly for $16. That bearing of yours looked like a common bearing........ just an idea.
Makes me wonder if the transaxle in my lawn tractor is full of plastic gears...definitely would not surprise me the rest of it is complete garbage so a plastic transaxle would definitely not be a surprise LOL.
Thanks Donny for showing us all what the bad China parts are, now I did buy a knockoff Honda for my wood splitter and 3 years of hard use still all good! Good and bad of china. If a motor is made in the good old USA I would pay a little extra for it. But that’s becoming far and few between unfortunately!!

@@BruceLee-ve6pi Today. Not when the contract was given to MTD to design and manufacture that transmission.

Maybe it was masquerading as cheap plastic 😂
+Mustie1 We shouldn't be too harsh on plastic per se. The plastic gears and whatnot aren't what failed, it seems, but a good old fashion bearing.
+Dale Grote
It's funny in a way, like the way a rubber seal cuts a groove in a shaft.
That soft rubber,polishing the metal away....
Guess that's why the friction wheel transmission has lasted the test of time.

Well... I know the tech behind plastic has improved a lot... but that was surprising seeing most of the transmission being made like that.

The steel bearing heated with plastic gears. I think there are too many moving parts for a snow blower.
So it was the metal parts that failed and not the plastic. Not sure if there is any way of abusing the transmission to cause failure?
Had a blower come in with the same transmission today Dony - price on that unit is now $612 CDN plus tax! Not even worth fixing.... Sad
Yes not worth the fix. A shop charges part plus labor. Can be an $800 repair.

Some within an hour are broken. Some of these machines are over $1000 dollars and the warranty gets you another crap transmission.
I think I would avoid buying any snowblower with this type of transmission. Complex, apparently unreliable, can't be serviced, and expensive to replace. I'll stick to the simple and reliable friction plate transmission.
+Brian Taylor It does seem to be over engineered for what it's supposed to do.
Agree... Any component that relies heavily on nylon gears is simply a problem waiting to happen. Looks like it was designed from the ground up to be a frequent & expensive Failure.
@@taftr Canadiana put this crap in their snowblowers. Cannot try to shift if the machine is not running. Know folks who had these and they were broken within an hour of use.
Another attempt at over Engineering a simple process The old Transmissions very simple in design worked for many years with no failure at all these are in almost all newer Sears machines JUNK
Just a guess, but a heat gun might have softened the adhesive and made it easier to separate. I'm guessing it's just RTV.
I used this video to repair mine, same thing happened part # Nsk 6002cm 802. Definitely a poor design ,I would recommend replacing that bearing with a bushing of the exact same size. That’s what I’m doing if it happens again
As one of the other commenters remarked, it is a poor design and the bearing failed because they are using it to apply side force to the cone clutches. I'm going to see if I can get a more heavy-duty bearing to replace it with.
the bearings are common 6002....i recommend buying the best you can find.....its an awful design that applies side pressure to that (those) bearing(s) to engage the cone clutches (which are inside that plastic gear next to the bearings and driven by the worm input)...they used a radial bearing in an application that requires thrust type bearing
How would you even add fluid after you resealed it?
Add the oil when the 2 halves are split open and before you put new sealant and join the 2 halves
does the bearing have any #'s on it? likely an industry std size. you could check mcmastercarr for one of the same size and design. easy to navigate website if youve never checked it out. gotten me by repairing just the bearings on a vacuum motor once when thats all that was wrong.
I have a Briggs and Stratton Brute blower with the plastic transmission. I have had it in for service 3 times because there isn't any difference in speed in 1st or 6th, it is all slow. Sometimes i have had to actually push or pull it back to my shed. The Briggs repair never said any thing to me about the transmission being an orphan. About 3 weeks ago Briggs approved a new transmission exchange. I have used it twice and there isn't any improvement in the way it works. Briggs refuses to admit that there is a problem with the units. BEWARE
People don't know they are getting this junk in the ear case because you can't see it. Hope consumer protection does something here in Canada.
I’m having this same issue. R1 doesn’t work at all and R2 is as slow as R1 or worse. Same forward speed with all 6 speeds. Occasionally it will shift properly. I’ve used this blower maybe 10 times. Since I’ve owned it. Any insight on this anyone?
400.00 dollars for a junky plastic trans, Dang! I believe i would've tried to find a good used snow blower that did not have that type of trans in it for that. GOOD INFO.
thanks for this video, I really appreciate it so very much. I'm sure I will come up against one of those transmissions in my own shop sooner or later. People may try not to abuse the transmission if they know it's all plastic ;-)
I’m sure you could find a replacement bearing by measuring with a caliper.
Wow. What an over-complicated mess of cheap guts!
Makes me appreciate my life long choice of Ariens blowers even more! Simple, robust, durable, life long.
at 3:17 the plastic gear right above your fingers is connected to the input shaft but is not driving the shaft it is on. Likely related to the misalignment of the shift fork which is caused by the bearing failure.. At 3:49 the gear you will point at has nothing wrong, it is not engaged. As for the failed bearing, it failed because it has a load on it in a way that bearings of that type are not meant to handle (pressing on the side of the bearing. This will be the common failure point of these transmissions. If you were to contact any bearing supplier and show them that, they will agree. I would not pay $400 for a replacement transmission, I would replace the snowblower because this will happen again unless they change the design. This is an obvious defect in workmanship, and likely an intended flaw (planned obsolescence).
not trying to say that i'd rather have plastic gears rather then metal cause obviously metal is far superior however i have one of these units and have had one for around 4 years now and all the plastic parts are just fine.. only issue's i've had are vibration related.. gotta keep on top of torquing all the screws/bolts regularly however that being said the flywheel that moves to change your speed has given me problems to the extent of having to lube it up with some good quality grease cause it has a tendency to stick in gear i'm assuming because the flywheel just sticks and your left with your rig only being able use 1st gear. For a guy that has a super long driveway that is annoying..
Love the video though i was tempted to take the transmission apart and now i'm glad i didn't heh.
Hey Don, cubbeezx comment was my first thought. We have to catch up. Stay well.
+JOE Z yes for sure Joe!
My friction wheel drive lasted 12 years with simple maintenance, 100$ 2 belts and friction wheel, good to go for another 12 years. Suprised to see plastic junk like this in a snowblower.
What a peace of junk! Plastic, plastic and more plastic and what fails a steel bearing :) Great video I am also interested in "new" design of parts like this what is inside and how is made.
excellent video Don so cool you post it .!
I would think NOT to purchase a Snow-Blower that has this transmission, instead to get a snow-blower with manual mechanical rubber friction wheel for shifting. What was that brand snow-blower with the particular transmission that cost over $400? Let us know please.
thanks for this dony...
Those are bearings designed to work like a sprag clutch. They drive in one direction only.
I love it when someone says I've never worked on one if these before , and the guy looks at you like hes horrified.
Come on, techs can go back to"basic training 101" theory and use that.
You did pay attention in tech school right?
When something doesn't have a manual, you gotta go back to theory for your diagnosis.
My other favorite is to say "let's see what happens " 😂😂
That makes eyes go big too!!
+MrTheHillfolk the manufacturers don't want us guys working on these, not even a parts list available, parts not available either
+donyboy73
Of course not.
That is what makes it fun to take apart mystery boxes that any service performed on, is shunned by the manufacturer 😂
It's kind of sad everything is going toward an assembly with no parts available.
Great informative video on exactly the same transmission l,m having a problem with. Who designes these machines ?.lts very frustrating trying to access any cables etc.We just had 0ver a metre of snow and my machine,s tranny went just as l was finishing up.they should stick with the old friction wheel Keep it simple stupid.Thank for the great videos.
We also did such a defect. Only it makes no sense to do it. There are no spare parts for this transmission. Sell and install new ones.
are all tran using plastic gears?
nice video
No. Some still use good components. Problem is you can't tell easily.
that's a shame, what happened to the old school transmissions which where aluminum or steel, they must not have used high quality bearings, that's the quality of MTD & Murray
Gee? I watched one of your other videos saying when buying used to stay away from the plastic transmissions. I see why. $$$
If you buy a snow thrower with an MTD transmission who's vision is delivering the best consumer experience then this is what you can expect when it breaks .
[quote] this part never been available for the aftermarket.
Unfortunately only the complete transmission is available.[/quote]Stick with a friction wheel!
+Kevin Watson yes I still prefer the friction wheel lol
Hi Dony,
I buy used snowblowers quite often, which snowblower did this transmission come out of.
I would like to know, so I won't buy it in the future thanks.
+Aaron Lumbroso a craftsman, one that is made by murray
+donyboy73 I thought Craftsman was made by ayp and Murray by mtd?
+Aaron Lumbroso Not anymore....
+-Doug - Briggs and Stratton now owns Murray, but Murray has been at the lower end of equipment. Craftsman no longer uses AYP, the lawnmower decks for instance are made in China now and have plastic parts. MTD used to make quality products as well. Now there products are also low quality.
How old it that transmission?
I had a Sears snow blower in 2013 with this transmission and it only lasted three months before it broke. Sears Just kept replacing the transmission till it was out of warranty. Had to junk it and buy a different brand of snow blower. Never buy another Sears snow blower.
The bearing was running in oil too, must have been faulty. Did you try to substitute a bearing from something else? I once had 2 needle bearings go in the transmission of an MTD and the parts supply store said I had to buy the whole thing..... over $200. My buddy down at the auto parts store had a bearing out of the transmission of a dodge car that fit perfectly for $16. That bearing of yours looked like a common bearing........ just an idea.
i can't belive.... why they use plastic gears on the trasmission? in my opinion steel is more reliable
Precisely why they don't use it.
+SootySweep22 i'm also not surprised to see molten plastic
You get what you pay for.
Makes me wonder if the transaxle in my lawn tractor is full of plastic gears...definitely would not surprise me the rest of it is complete garbage so a plastic transaxle would definitely not be a surprise LOL.
It's more than the bearing, something sheered on that shaft.
Cool
How OLD is that thing???
Thanks Donny for showing us all what the bad China parts are, now I did buy a knockoff Honda for my wood splitter and 3 years of hard use still all good! Good and bad of china. If a motor is made in the good old USA I would pay a little extra for it. But that’s becoming far and few between unfortunately!!
$245US is the best I saw online for one of these!
General Transmission piece of junk, stick with Hydro Gear. As usual an excellent and informative video.
The bearing obviously wasn't designed for a thrust load. Bad engendering poor design.
That or a no name Chinese bearing was out of spec and mexican line didn't catch it. A Timken made in a first world country probably would have held.
Please save. Who found parts of 1733972YP parts for gears? I want to repair cheaply without global purchases.
Thumbs up
