Fixing the Broken Transmission Brake ~ 1988 IH Scissor Dump Truck
HTML-код
- Опубликовано: 27 сен 2024
- We got the old International home, and I BROKE it right off the bat! GRRRR Today we'll figure out what needs to be fixed & what it's gonna take to find the parts and get it put back together!
I also did a little creative swap with another one of my trucks before I sold it!!
This truck is a 1988 International S1754 Scissor Lift / Dump Truck that has a Navistar DT360 Diesel engine in it and a Spicer manual transmission!
I've Got BIG plans for this truck, so you'll be seeing quite of bit of it in the future!

If you have any suggestions, questions, or comments, please leave them below!
Thanks for stopping by, I truly appreciate your support!

The fact that you show your mistakes and how to fix them is why I am a subscriber, me all make mistakes, cheers buddy!
I like watching your videos. You break things accidentally like I would and then you show us how to fix it . You are an everyguy. I appreciate that everything you do isn't staged to look like you don't make mistakes.
Also, I love watching you wrench on old machinery.
I feel your pain. My dad and I have a 1600 with a dt466. He was having some welding on the dump bed done and the welding shop didn’t have the parking brake off. Kept stalling the truck trying to move. Soooo their approach was more power - floored and and let the clutch out. Totally split the 5-speed in half right below the shifter. Oil, gears, bearings all on the shop floor.
OH MY!! I'm sorry that happened! I will say though, I'm glad that didn't happen on mine!
🤭😬
Yeah, sounds like that shops going to buy you a new transmission for free LOL
The reason why that relatively small transmission brake caused so much damage is that it's braking effort is multiplied by the reduction ratio of the final drive crown wheel and pinion. All transmission brakes work that way, which is why they should never be used for deceleration, only parking, unless the power-train has some hefty mountings, even then, there's a danger of causing some transmission wind-up, that's opposing forces locked into the system. Check the temperature of that drum after a good run. Good video. Cheers.
A trick to dayton spoke rims that could actually save your life. Loosen lug nuts but don't fully remove the nut, then tap each wedge with a hammer. This way pressure releases without sending anything flying
I agree with you! Thanks for the concern!
That's why their called widowmakers
@@shadowbanned69 The rims (older styles two piece) are what are referred to as widowmakers because they can explode (separate) when inflating, not because of the Dayton spoke wedges. The wedges however could take out a kneecap or bruise you something fierce.
The new oil seal is upside down. Spring side always faces the inside oil side. You should never be able to see the spring from the outside of any oil filled housing. Your transmission is going to leak worse than before once it reaches it's max temp. 👈🤓👈 Before 4:41 After 24:01
exactly
That's where I'm at in the video now and I've spotted the same thing oil seal is backwards
In this case you're correct but sometimes the seal would go the other direction depending on what it's purpose is. If it is designed to keep dust and debris out then it would go with the spring facing the outside. It's not super common but it does happen sometimes.
@@DoRC possibly but the video does show it facing the springs in so my way of doin things is to replace it as it was unless it definitely shows it was reinstalled wrong
Yeah maybe, but I installed it in the same direction as the one it replaced... I guess we'll see if it leaks, and if so I'll replace it then... for now it'll do more harm flipping it around, especially since it's not under pressure or fully surrounded with oil at all times.
What a good neighbor you are
Good recovery, and thanks for taking us along.
It’s a great versatile workhorse. Congrats! I’m not a mechanic but I do work on our vehicles. The one thing I despise is working upside down and backwards in a contorted position, trying to unlock a seized bolt, and finally pounding my knuckles, in the frigid cold of Colorado. 🤦♂️😂
a trick for making heavy tires easier to remove and install is to use a d handle scoop shovel. you can use it as a lever to lift the tire, and as a carrier sled to move them into place. it's saved me a lot of fighting them on and off of things over the years.
Learning from one mistakes makes it a bit less painful..thanks for sharing your experience. Also thanks for the into to Maverick!
We have those style e brakes on all our 3 ton GM grain trucks on the farm. Stuff happens... Just be glad no one got hurt. I had a oopsie on saturday myself. The wind decided to take my door on my 973C and slam it shut while i was trying to clean out a mouse nest from the cab... Spidered the glass so bad... Working for free it seems.
I am amazed that you were able to get that trans to pop into gear while the truck was stationary without disengaging the clutch!
It takes a real pro to pull off that stunt. Loll
Dude a little JB weld and you've got that fixed and back on the road 😂
Yeah I should have dipped it all in a gallon of JB and it would have been brand new!! lol!
I'm sure your heart completely dropped when you bump the shifter and heard the bang
@@rayoverstreet9254 it sure did! At least it's fixed and im a better more knowledgeable mechanic / operator now!
Fun issue with this style of brake - if the driveshaft fails. My dad and brother were driving a mid-late 70's international set up as a water truck from a fire call one night, and had to go up a short but steep hill (10-12% grade). About 1/3-1/2 way up, either a u-joint snapped or the entire drive shaft gave out when dad shifted, the remains whipped around at high speed and ripped out the air lines and wiring. Now they're going backwards with a full tank of water, steep drops, with a house on one side, gas station on the other and a motel beyond a stop sign at the bottom. By the grace of God, they got it to the bottom of the hill despite no lights at night, before the truck was totally uncontrollable and ended up rolling it. Definitely only a parking brake and not an emergency brake.
wow lackey them or dam good driving to save lives of others when they could have just jumped dam heroes there i say
I don’t know much about these things but if it had air brakes don’t the brakes long on if air pressure is lost?? Genuine question mate as I only know a little bit about newer trucks
@@jimbobkirkwood828 they do now. I think the change was made to trucks either late 70's or early 80's. This truck predated the switch.
Cheers for the replys, learn sumthing new everday👍👍
@@jimbobkirkwood828 I'm late to the party, but what you're referring to are called "vacuum brakes." They're a type of air brake that fail to applied. Older air brakes used the air to apply brake pressure; vacuum brakes use air to remove brake pressure. I believe trains in the US use vacuum brakes as well.
Nice Job! Good recovery. Don't feel bad, we all break our stuff sometimes. It happens. Its better off now with new guts in the E-brake too.
When you install Dayton rims, you need to check to make certain that the rims are straight on the wheel. Put something alongside the tire. Spin the wheel and see if the space is the same all the way around. Tighten the wedges accordingly.
Fantastic work!!! Always anxious to new videos!!! Maverick is beautiful!
I like your comment "I'm getting a crash course on how this mechanism works" you can learn by example "school" or by experience "life".
Experience is the ability to recognize a mistake when you make it again.
I've learned a LOT from the experiences I've had, and I have no intention to stop anytime soon!
Great stuff, would love to see you working on OLD Red again 👍
Fascinating video, great dog! Thank you.
Has it crossed your mind that the cast iron housing is a replacement for the aluminium housing as the aluminium ones have a habit of exploding?
Saying that the aluminium could be a weak link saving the gearbox? Food for thought. Lovely dog BTW.
Totally love your enthusiasm, your quite right that's it's normally the problems we cause which need more to fix.
Thanks for posting and sharing. Great to see that you were able to repair the broken brake assembly. I hope on of your followers has some insight regarding the lagging in 4th.
stuff happens - don't beat yourself up - sometimes you're the bug - sometimes you're the windshield. lunched it good. there's a lot of crystallization and metal fatigue on that housing.
seems like the trans ratios were set up for a diff splitter. that's a dam good old truck - you got fortunate. I like Mav too - he's a good boy and seems to want to please
Would love a quick update on Old Red? Where's that project stand? Did you hit a wall?
you see the rign on the outer bearing ring? play is gone when that ring is pinched between the oil seal cover and the transmssion housing
The output housing retains the output brn. Stiles change by application, you should be good.
Perfect! Thank you!
I can already see that being.A very nice work truck!
Great video loved it glad find parts was very enjoyable thank you for sharing and your time as always dont miss a single one.
Maverick is a Beautiful Dog!!! Awesome!!!
I suggest you fabricate a flip latch for the gear shift that will allow you to have a positive lock-out of the shifter, one of the older fire trucks in our department had one that was mounted on the dash and would be flipped onto a pin that was on the shifter that prevented the movement while the pump was engaged, we also had a tag on the PTO and the dash that said LOCK-OUT SHIFTER BEFORE USE OF PTO.
That is actually a great idea... I also want to do the same for the parking brake lever since it's the PARK for the truck and it's EASY to accidentally disengage it! I've already had one of the dogs and on of my children accidentally disengage park! Thanks for the idea!
@@SalvageWorkshop yikes! My first wonder was about a transmission lockout. I thought I remember those brake levers had a pretty good detent? But that was a lot of years ago on an army truck (when they still had 3 pedals).
@@KristaMae If they are adjusted right it should take a very intentional action to disengage it.
Beautiful pup…. Great video bud.
Did you remember to fully weld the parking brake lever before final fitting?
Maverick is a very handsome puppy, and I'm glad you're finding other projects to keep your channel going, but how about a update on the track loader?
Great job as always. I got a feeling any thing can be thrown at you and it would get it fixed.
Lol... well, I will say there's nothing I won't TRY to do!
Can't have a dog, because we are at work all day.
A Cat, however, pretends to be your friend, but doesn't care if you're there or not - lol...
Another great video - amazing recovery from that error and sadly doesn't look trivial to avoid that problem. Really like reading the comments after seeing the videos - some important ones about the seal and definitely update us on Big Red!
Cheers for a great video buddy. Loving the dogs
Glad you was able to Fix it and replace broken parts :-)
Make sure you top of the transmission fluid.and grease the u joint. And recheck the wheels after the road test
When you take Dayton wheels leave the nut on until you break the wedges loose. Leave a few threads on nuts
Nice fix. Thank you for your video.
Good to see you got her all back together. 👍👍
When tightening Daton wheels set something on the ground and spin the tire as you tighten the wedges. If you don't the wheels will not tighten on straight and will wobble.
Save your clutch by not revving the engine to take off. I had the identical truck and even loaded it would take off at an idle 99% of the time. If you have trouble with it make sure your idle speed is set right, I had to bump mine up to get it back to spec
As for the big jump between 3rd and 4th, that truck was made when the national speed limit was 55. It was geared to run at 55. 4th and 5th are close together to climb hills at speed better.
Great job man you seem to be able to fix anything looking forward to updates on all the other episodes the caterpillar would be cool but you should be able to get a good price for these trucks thanks for the good episode keep them coming 👍
Yep!, that was pretty dumb, but it gave you a good reason to learn exactly how that system works, so it all wasn't for nothing,👍, lol, thanks for sharing.
The broken plate that you took off secures the bearing in place
If you haven't already check that the parking brake isn't dragging, by checking the drum isn't getting hot. I would offset the front hitch point to the right of centre, when you are pushing a tall trailer or a flat trailer with a tall load you can see down the side of it.
For a 1988 model year it is incredible at the lack of rust on the under carriage framework.
After 2 or 3 years in New York State vehicles are already headed to the scrapyard due to
heavy salt use on roads. Same here in Canada. Also have never seen a scissor lift dump truck. Other than a novelty what practical use do they serve? 👍👍👍🤩
When removing a Dayton wheel always leave the nuts on the studs after loosening. Then smack the wedges with a hammer to loosen the wheel from the hub. Those wedges will get you.
When do you post a new video of “Old Red’ again? Greet channel, keep up the good work 👍
Either shims go on the bearing to limit the end play or it’s the crush torque on the yoke that bolts onto the shaft
Enjoyed this thanks Boston Uk 🇬🇧
That must have been quite the shock to see the chaos created by the slip of the gear selector.
Better this way than runaway
hell yeah a tow hitch vise in one.
you,ll propably need to reconnect the ruxel high gears,i was young and they got me driving the fuel truck ,and a pro gave me a trick going 12345 low then pull it in high gear go to 4 high then five high,it was nice,this guy was hauling heavy sand loads,he propably was doing other things too i wasnt going far just fueling equipement,i had no experience at all,i did a boo boo too one of the firtst times forgot the parking brake on,like you say you learn by experience,nice video
Its ok bro we all make mistakes !! It has happened to me BELIEVE ME !! Hey at least it was all replaceable and semi easy to remove and replace.....but I'll tell ya what I really enjoyed this video !! I have never worked on a truck like this and it was a GREAT learning experience for me .....and that's what it's all about !! I am sure this is not what you wanted to do but it was a great video !! Glad it all worked out !! And Maverick is a good boy !! Sweet more cool project video's to come .....I love it !!👍👍
MERRY CHRISTMAS AND A HAPPY NEW YEAR
Maverick is a beauty.❤️
Nice job 👍
The key to making f... ups is having the ability to fix them.
Another great video.
Cheers
Michael (from Scotland)
10:52, you're partially correct. That output housing (or tail shaft housing) will push on that snap ring on the bearing toward the main case and take up a lot of that end play. Then the yoke nut will pull the shaft out, keeping that bearing pulled against the tail shaft housing. They're ball bearings, not taper bearings so some end play is expected.
Welcome to the show, Maverick!
bruh your seal is the wrong way round, its supposed to be lip towards oil
Doh! You clumsy Oaf! 😁
Is great recovery repair
I had an International tow truck, same loss of power shifting into 4th until a truck driver showed me if you take it up to the red and let off the gas slightly while shifting without using the clutch it retains its speed. It takes some getting used to but once you do it it's hard not to. I think it's called power shifting. Hope that helps, you have a good truck there in my opinion.
actually i did it in every gear except 1st and reverse, hardly any wear on the clutch I put in it when I bought it too.
Luv ur channel ,sir.. ur a great teacher ..
Good fix! Hi Mav!!!
One step forward and two steps back, hang in there.
That old drum could be turned into a nice ringer bell for your workshop
When putting the rim back on the hub. Set a hammer on the ground in front of the tire and spin the tire. tighten the wedges accordingly to true up the rim.
Another great repair video.
Two speed arse will fix that thing when loaded and up hills. Cheers from Australia
Good fix!
that housing fixes that end float by the looks of it
Most of my projects start with me saying the phrase “well here’s the carnage”
That's unfortunate!
I want to see old red!
JB weld should hold them good.
I think Maverick is afraid as hell of this truck but he loves vou and he wil follow vou, wherever you gp.
When pulling wedged wheels loosen the nuts and leave them on and hit the tire and the wedges will pop. Your also suppose to spin balance the wheels and tighten the lugs to make the wheel run true. Put a hammer handle next to the tire and spin it. Tighten nuts until tire/rim runs true.
Just watching this and I think you have put the Oil Seal in the wrong way round.. the solid side goes to external, whereas the "Hollow" side with the lip tension spring faces internal.
Love the videos, keep up the good work.
Nice job
The silver lining is that you have new brake linings.
trans is made/ geared for 2 speed rear
Tail shaft housing seal is in backwards, and wheels need to be trued by spinning and tightening the proper lug nut, to eliminate wheel wobble ! Tail shaft housing also clamps the tail shaft bearing in place, lucky it didn't pull out farther, might have had a few things fall loose inside.
What happened to old red? I was following it and then you stopped showing the rebuild
With those wheel keepers the leave the nuts on loosely and then hit the keepers and that way it will stop anyone from getting hit when they fly off
If you plug in a 2 speed differential you will only loose half your revs. The trucks of this age I’ve seen fitted with spider hubs are 8 ton or more load capacity were fitted with 2 speed diffs.
Matt, we need to get you a set of decent work gloves.
I like to “feel” things with my skin but some of these large parts are going to hurt your hands 😂
I call those Dayton wheels "cultavater wheels" and that is where they need to be, on a cultavater!
Seems you intend to use this , which is good . Was worried that all of your "rescued" vehicles would merely end up moldering away in your older friends junkyard .
Oh I intend to use everything I rescue, and NOTHING of mine will end up in that junkyard... I'd rather pass a project on to someone else rather than let it just rot away like stuff at that junk yard... If anything I plan to rescue a few things out of that junkyard!
@@SalvageWorkshop So glad to hear that , too many youtube sites are merely about "will it start?" . You'd used the things you'd fixed previously so good , that's great !
Nice video. You have to tell us what your little mistake ended up setting you back. I think may have installed that oil seal backwards, but otherwise nice job.
Put a winch in the front of the bed so you can pull things onto the flat bed
You’re fortunate you didn’t need the emergency brake on a big hill. I doubt the aluminum housing could have withstood anything but a parking brake load with shattering. Silver lining is that the steel housing will hold the load you need it to hold.
The original three speed transmission that would have been in my 1963 FJ40 had the parking brake on the transmission. The rear didn't have this. I'm going with a 5 speed in mine, so I'll also need to change out the rear so that I will have a parking brake.
Good upload. Good idea to do a series on this truck. Your subscribers want uploads more often. Can we have an update on the fate of Old Red? Cheers from Oz mate.
Enjoyed the video bro. Safe travels
