Abandoned Yanmar Tractor WILL IT START? Part 1?

- Опубликовано: 24 май 2020
- I found an old abandoned tractor in a field. WILL IT RUN? I'm pretty sure the engine is completely blown. We need to haul it back to the shop and check the fuel filter, compression, and injectors to diagnose whether the engine is blown. Is it a simple fix or a full engine rebuild? TOOLS USED ↓↓↓↓

This is a late 1970's Yanmar YM2000B 2WD diesel tractor.
These old diesel tractors are built simple and built to last.

I also know this is done, but those tractors have depression valves. Open them to crank over for easier starting and to clear the cylinders.
Also for those watching you usually never have to bleed injectors on those yanmars. Start at filter and work to pump.
Sounds like decompression valves are open to me as well. No compression sound and spinning fast
First thing I would of done would be check the decompression valves, pull cover and check linkage!! I think there held open.
Those watching this those are british pipe threads, close to american but slightly different. Don't mess your threads up. Word of caution.
Are these really British pipe threads? I had no clue. Thanks for the tip!
We just bought a YM 1600 that doesn't run. We'll be watching your videos. Thank you.
Nice!! The 1600, 1700, and 2000 are pretty similar. The 1700 and the 2000 are almost identical.
As soon as you hit the starter you could tell there was no compression
It's got that decompression lever too. I like to be thorough. No need to throw parts at something. You know what I mean?
What Up Y'all! Hit the sub button and the bell. Don't miss out on the Yanmar tractor rebuild! Links to all the tools used in the description PEACEEEEEE.

Congrats on the free tractor!! Just found your channel, great to see you fixing the little tractor, thanks for the video!
Thx, for the support!
Matt’s shop, thanks for not using starting fluid. I call that death to a diesel in a can. More in likely it’s broken rings. Or bad valves. But you can put oil in the injection holes and do compression test again to find out. I use atf for that. It could be stuck rings. But doubt that if it was running and quit. If it over heated then rings or cylinders.good luck. Glad to see it didn’t go to scrap yard.
I never use starting fluid on anything. In my mind, if it doesn't start on its own then it not fixed enough lol.
Everyone keeps saying blown head gasket, but I'm pretty sure the rings are broken.
Anyone wearing new balances, basketball shorts and a camo tshirt has my sub, no questions asked.
Haha thanks, I appreciate it!
@@MattsShopthis series is excellent, keep up the great work!
Just found you through the engine rebuild of this tractor. I look forward to watching the whole series. Subbed. Its fun to see the begining when i already know how it ends!
Thanks man. I appreciate it
Smart young man! A very thorough job and nice video
Thanks! I appreciate that you appreciate my thoroughness lol
I just bought a Yanmar YFL 875
For 800.00
With lots of attachments.
Haven’t even picked it up yet.
The guy says it ran when parked 😐
We’ll see on Saturday.
Glad someone said NOT to use eather
Cool, I have that same machine. Good to see another one.
Glad to hear there is a lot of these tractors out there.
Hey Matt, nice little tractor buddy. I think you did a great job going through all the nessessary system's and inspecting everything well. I think it's a great little project mate. I can't wait to see your next video. Stay safe and well buddy. 👍🤝🤠🇦🇺
Thanks man! I really appreciate it. You get it!👍
Video was good I'm glad your gonna rebuild it its a really nice tractor
Thanks man, yea it is!
Hey man new subscriber I love seeing these types of videos I revived a 60s lawn chief and a Dixon 304 from a. Junkyard and they both run and drive
As you have made up that adapter for the comp tester, just connect it to an airline with that cyl on TDC compression stroke and listen to intake/exhaust/ oil filler to find out where the air is going.
There's your problem!
Woah, that's a GREAT idea! Thx!
Time to fire up the pressure washer *electric pressure washer * lol
Haha yea, fire it up! (Plug it in)
Great video!
Great comment!
Diesel last for a long time just throwing that advice! I parked a 7.3 diesel for 3 years and had a full tank and it started right up and drove it until empty with out a problem
I know it does. The engine was suspected blown so I got fresh diesel. You never know if someone put gas in it by accident or some weird additives.
Got the same tractor gave to me it sat our in the rain for 25 years fired right up I love these yanmars
That's good to hear for when mine is running.
Very good.
SWEEEET little tractor!
I'm not a mechanic, but I'm suspecting a blown head gasket.... especially since BOTH cylinders have low compression. I also I noticed what appears to be evidence of a coolant leak over a broad area between the head and block deck... A blown head gasket could also be the cause of low coolant in the radiator. Hope that's ALL it is and you have a good engine that can be salvaged.... :-)
Thanks! I really hope that's the only thing wrong with it. I haven't gotten the head off yet. That's the next step. IDK though, there was no coolant in the oil???
No.coolant in the oil- probably a matter of engine and oiling path design, combined with .where the gasket is blown out.
Loosen the oil drain plug just enough to get seepage and see if you get water or oil.. :-)
I have a 1700 model Having saying problem. It got hard to start in, no start. I'm down to checking out the compression. Your video was real helpful on that.. Ann about the compression of release.. I have Did the outside check.. Almost certain it probably is low compression. Do you wanna rebuild the tractor for me? Ha ha, I do have a cup of mechanics around here MaryvilleTennessee.
I’m going to look at one of these soon. Hope it works out
Let us know what you find!
Very good video!!!
Very good comment. Thx
Smart man! I always say if it doesn’t start on it’s own something is wrong with it. Could be valves as well. I have seen even the compression release get out of adjustment to cause pore compression. Or carbon stuck the valves. Could be easy fix or pulling pistons out. Do you hear any air ex caping from exhaust or intake side? If no take oil cap off and try to hear if air is ex caping from the pistons. Oil should raise compression up. Would like to know what you find.
Exactly, I don't even own any starting fluid. Hopefully it is something simple like a head gasket. It's not the valves or a piece of carbon. I'm sure of that.
Nice!
Thanks!
HEY, DA. Check the Compression Release and the Valve Lash . VL was what was wrong with my 1500 3 cyl !
Because both of the cylinders low compression and it had no coolant it is very likely to be a head gasket which are rather common online so I hope you can get her to run again
I think someone tried to rebuild the engine and did it wrong. The evidence is that there is red RTV silicone all over the engine. I hope it's just the head gasket.
Oh, it'll run. Just a question of how much work I gotta do👍
There’s a gasket goes between the injector and head it might be leaking 🤷🏼♂️
Good guess. but it was more than that.
Injector 2 was atomising well but injector 1 was squirting like a peeing cherub.
In any case they’re both banjaxed now that you took them apart. No point in trying to repair injectors unless you have a pop tester and the set up data.
All that aside, your head gasket is blown.
Keep learning, you’ll get there 👍
I'm already "there"👍. One fitting was loose that's why that injector dribbled. I put the injectors back together the same way they came apart. No mixing of parts between the two. The shim stacks where put back EXACTLY as they came apart. They are going to someone with a pop tester if the thing doesn't run right after I fix it.
Are you still going to rebuild this motor? That would be extremely interesting to watch some of it!!
Yes, I will be rebuilding it very soon.
HA!!! When I started watching this, I was like " SWEET Anthony Kiedis of the R.H.C.Ps got a sweeeeeeeeet tractor! I never knew he was so knowledgeable about tractors."
Just first thought, is the decompression lever in the start and run position ?
Yes, tired it both ways. On and off.
That is a beautiful tractor!!
Thank you!
@@MattsShop Are you in Florida? I am in Pa. I went to USF for my PhD in chemical engineering.
tries to turn the engine at 12:24. Just so you know.
Hi Matt, I watched a video you did on the rewind of a pull cord on a sthil chainsaw. When you went outside to start it I noticed the pull cord looked difficult to pull, but you did manage to start it like that, now I have a situation where my pull cord is like that but much harder to pull and am unable to start the saw, would you have any ideas on what I should do to make it easier.?
subscribed thanks man
Thanks for the sub!
I’d take it head gas easy only 2 cylinders easy rebuild if needed. Fun project!
Should be easy either way!
Like the video,, would like to see the rebuild, Yanmar for the most part makes a good product, maybe for a the money will be ago rebuild
Stay tuned! It's getting rebuilt!
Did you check the decompression valve? My ild yanmar really similar to that one had one. Ended up needing new rings and cylinders to run but they are great and tough tractors
Yes I did. Great info, that's what I suspect is bad.
Matt's Shop 👍 good luck with it. Mine was over heated and then parked before I bought it. The cylinders we ovaled and the piston rings nearly had a 1 inch gap!
Looks almost NEW!
I'm gonna get it as good as new!
Hi Matt , a three cylinder yanmar with the same injectors. Im getting no deisel in the fuel line back to the tank . Im getting the injectors tested , it starts up fine but after losing power one day i noticed i was making oil and had bad blow by , what da ya reckon iscausing my return line to not be working its not blocked. Thanks from Australia, love ya work mate
Can you suggest where online to find parts lists?
My old Yanmar YM236d glow plugs, tyres & parts...
Here's a YM236D parts manual I uploaded for you :) drive.google.com/file/d/19EQqr9V_K8byeKlt5OcN_CTfrDjvjxRw/view?usp=sharing
Just rebuilt my ym2000 a month ago, I'll give them one thing, their reputation of being nearly indestructible is no exaggeration. Just don't let it ever overheat (>160 degrees F), and never use ether (instantly kills the rings and scars the liners). Ask me how I know, lol.
Nice! Any tips you'd like to share with anyone rebuilding a Yanmar engine? For sure, the starting fluid is a big no no. I don't even buy that stuff.
@@MattsShop aside from the obvious things like taking your time with cleaning everything and assembly, best advice i have is to use lithium grease before you fire it back up. Also, be aware that there are a ton of interference fit parts internally, so freeze the new wrist pins and pistons beforehand, and don't force anything together, should all just slide apart/together by hand when cold. I let everything warm up to room temp once it was together before compressing the rings. Also, there's 2 o-rings (square rings if its factory original) per sleeve. According to the guys at hoye tractor, the sleeves don't need to be changed unless they're scarred or pitted, new rings will make it cheaper on a rebuild. Personally, I'd buy 4 sets of rings and 2 new sleeves if you're going to go that route, just in case. Total price on my rebuild was about $800 in parts at the time.
Yanmar makes a great tractor (used to make all of JD compact tractors). Yanmar marine diesels are prolific and very reliable. This machine is worth saving.
Exactly, everything you said is 100%. I have seen the John Deere/Yanmar combos. Yanmars are awesome Japanese quality.
The right injector was working fine but the left one was not! Right was a fan spray left was spurting out
The fitting was loose. If you look closely it was dripping.
Having problems with my ym1300d hydraulic fluid is leaking underneath the transmission what do I need to fix this
Is it leaking from the triangle shaped plate under the transmission? There is a filter, o-ring, and gasket in there.
I have a Yanmar YM2010d These are great little tractors and pretty easy to fix. However, there are a few Models to avoid. Check out Hoye Tractor for your Yanmar needs and the models to avoid. Very helpful people there too.
Yes, they are. I realized that you should avoid some models. Luckily this YM2000B has nearly every part available.
Usually head gasket only takes out one cylinder. Should still try to start on one or the other. The two cylinder diesels will run on one cylinder. Unless it blew out in between the two. But both should be same compression if that’s the case. Fill radiator up with water and turn it over. If you see water coming out of the injector holes you will know. Or put injectors back in and see if you get air bubbles in the radiator. I would believe on the pistons aren’t happy or the rings. Probably got really hot is my guess. But not there myself so just guessing.
When I took the valve cover off I could see puffs of air coming from where the head meets the engine block. I hope it's the head gasket, but the oil had ZERO coolant in it. Unless it blew out in a way that didn't compromise the water passages sealing.
I still think it's the rings/pistons.
Nice
Thanks! Stay tuned!
Using a snatch block will help a lot and is much easier on the winch.
Great idea!
It's called moss ( the green stuff)
i had one of these it was great
just 2 hard to get on and off
Yea, it was definitely designed for petite Japanese people for sure.
I've had the same thing happen before when the decompression lever had gotten into a position it shouldn't have been in (the lever was 180 degrees, partially decompressing and it wouldnt disengage without being flipped around manually)
I wish it was that simple, but I pulled the valve cover and disconnected the decompression cable. Still bad compression:(
@@MattsShop its possible that the lever itself is stuck, can you easily remove the lever that the cable was connected to?
otherwise, this would be a good tractor to conver to electric
Matt, Could you do a vidio on adding a hydraulic top link to your yanmar. Thanks.
I don't know. I plan on doing a loader and maybe a 4x4 conversion when I find the parts.
I was a tractor mechanic for 15-16 years back in the 70's- 80's. John Deere's little tractors were made by Yanmar...the 650,750,850, 950 on up to 30 hp were all just Yanmars.....
That's good to know. I wonder if the engines were the same at all. I'll have to check into that.
@@MattsShop Deere did change specs in some areas, for the most part though you could exchange parts. Where they made them different was coupling the different components together as in a 650 deere may actually have the transmission of another equal or larger model from the yanmar. Most if not all regular maintiance items will interchange....I don't know where the new deere's are made, I've been gone from the tractor world for 21+ years. Those little yanmars were kubota's competition...good tractors. There was a time no matter the brand most 30hp and lower were coming out of japan. There are a few exceptions.
I doubt it will start with that compression because not enough heat is generated. Diesel engines are around 20:1 as my old grey matter remembers.
Ya need to replace the head gasket. Then put a little oil in the cylinder and turn it over a few times. This will help seal the rings. Then see if this brings the compression up.
You should see a fine spray out of the injectors. If it looks like a squirt gun spray it won't start. That piston in the injector is super close tolerance so be careful. The shims regulate the amount of fuel that is sprayed into the cylinder so don't mix them up. Looks like the pump is working and that's usually the first problem. Make sure the filter's and/or strainer's are good on the pump.
Good luck
Haven't watched the whole video yet, so I'm going to guess. No compression. My money is on a blown head gasket from a warped head. Second guess is valves not seating, but I doubt it. No coolant in the cooling system is the smoking gun. Update, burnt valves is my new guess after seeing the compression test.
Alright, we'll see who's right. I say it's bad/broken rings, pistons, and/or sleeves. The valves/seats probably need to be trued up too!
хороший трактор надежный и простой лайк и удачи
Thanks!
That's a YM200B. A great unmolested Yanmar. Watching now but I'm sure that one will run with little work. Worst case someone over heated it and blew or cracked the head. Just a gasket is not a bad job. Don't use starting fluid you will break rings and blow holes in pistons.
Yea, these Yanmar tractors are good, but the parts aren't cheap lol
@@MattsShop I have found the parts to be pretty cheap? Used parts for them are not that cheap like if your trying to buy a used part compared to old american iron but when your buying parts at Hoye I think parts are pretty cheap for them?
I was given a yanmar 1702D with a front end loader, how easy is it to get parts
Very easy! I get parts at hoyetractor.com
I have an 18HP Yanmar diesel and after power washing, it will not start. Starter will not engage as ig the shifter is not in Neutral.
Any ideas, Please ?
There are no electronic ignition parts on these tractors. I'd start with the key ignition switch. I believe there is a starter solenoid. Probably got some water in somewhere.
@@MattsShop Thank you .. I did not get water into the ignition switch. I crossed the solenoid connections and it works but it does not engage the starter. There are also fuses mounted on the block that are good fuses. i am confused.
Do a second test with oil in the cylinders to see if the pressure is different from the first one or not. If it's different than it's bad rings
If it's the same then it's a blown head gasket
I tried the oil trick. It didn't help. Pretty sure the rings are broken.
@@MattsShop Do not, Do not, Do not use the "ol' oil trick" on a diesel engine!!!! This diagnostic procedure is only for petrol engines.
Lost compression look at the valve cover gasket all that rust.
i looked at a YM2210D tractor today and the oil is grey like and nothing in the radiator. Should I run or pick it up for 2k. It runs and drives
It makes me worry. Is the oil milky? It could be a blown head gasket. I'd say $2,000 max unless it does have mechanical issues. Ideally you would do a compression test and radiator pressure test. Difficult to do "in the field".
@@MattsShop he called and said he changed oil and filled radiator and running good. I think it might need more work like rebuild kit. Then everything else is 40 yr old or more. He is aksing $8K with new loader, box blade and brush hawg.
8k is a lot for that especially if it has mechanical issues. I wouldnt pay that much.
ues some Vinegar to clean the radiaor,
Check out part 2!
Tough break!
Yup, it was free though!
unload with jack under front of trailer. put tractor in high and push it back and forth. will show if engine is locked and if it has compression. old school. tell by cranking no compression.
Nice old school trick.
Everyone has to start somewhere. Haters going to hate, as long as someone is bitching you know you must be doing it right. Your shop your rules and leave it at that
I was told it had low compression and I suspected low compression. I do things differently. I assume I know nothing until I prove the problem. Otherwise you are throwing parts at the thing, never really diagnosing anything.
Pull the compression release.
It was on.
not to be a jerk but first thing you should have done is get that compression release control working properly. those engines are tough and last a long time if maintained
It's the first thing I checked. I ruled it out in about 2 seconds.
free tractor is a win if it doesn't start
It is if it's worth fixing and you film it lol
Two cylinders having low pressure like that would be suspect. Seems like it'd be an easy fix.
You would think...Wait until you see the rebuild video.
Hopefully not cracked head. With not knowing what it looks like under valve cover. Should be around the head and block meets is where you should be seeing air puffing out. Not under valve cover. Could be wrong tho.
I hope not. That gets expensive FAST!
Check the decompression lever make sure it isn’t dtuck
Stuck
Disconnected it. It's blown.
make sure the compression rellease is off
Yup, did it both ways!
how to install a power pack on a 1994evenrude motor
Decompression lever is on
Nope, won't start both ways.
Fix your compression release
Nope, not the problem.
It's worth fixing you can rebuild it real cheap
Yesssir
Good opener up and get a bible for the tractor.
Service Manual? Lol never heard it called that.
Great video, What year is that tractor. I don't much about Yanmar tractors.
These old Yanmars don't really have "years" they were all pretty much the same throughout the years. This was built somewhere between mid 1970's to mid 1980's.
@@MattsShop Thanks
Do you still have that tractor around? I have one and need a part.
I'm rebuilding the engine as we speak.
@@MattsShop Awsome! This is a neat little tractor! I have the tiller too. I just rigged up a snow plow! good luck!
@@MattsShopgreat video. Can you tell me what the head bolts need to be torqued to? Hoye apparently changed hands and have no info and I cant find my service manual. Thanks
looks to me likr your not getting any fuel to the ejector
The fitting was loose
valves are stuck open
Guess again!
The engine is done it needs to be fully reconditioned, c"mon if it had a been good you wouldn't a got it for nothing.
Yup, pretty much sums it up!
Hey bro where you live? I have yanmar too. And i have question
I live in the South. What's your question?
Just pour some thick oil down the cylinders let it sit for bouta week then try again
Tried it. Still had bad compression.
Decompression lever if you have a weak batter hold lever and turn key when its spinning fast let go of the lever and she starts
The lever on this thing is a cable that is either out or in. You can't just turn it on or off easily.
@@MattsShop that's cause yours is old
diesel is good
Your compression releases down Pull It Up
Step on the clutch to start.
That doesn't effect the engine.
if it drain in to the engine the oil would look muddy
Nahh, it's nice and black oil.
You should have tried starting fluid at first try
No way I would ever use starting fluid on a diesel.
Moron gives advice that destroys Diesel engines. 🤦🏻♂️
put your compression relief valve closed
Yanmar motors used in many sea going fishing boats. Those guys no what's reliable..
That's what I've seen they are used in a lot of larger boats and heavy equipment.
Dissle
Amazon,,wins again!!!!
Compression release is open
Did it both ways, still had low compression.
I see sure would have been sweet if it could have been that simple 👍
I know right! It was stuck open when I got it. I was sure that was the problem.
N
