As a New JD 350 Dozer owner. Im looking forward to watching all of your JD 350 videos as well as your other videos on your channel... Did I mention -- You're stuck with me now -- I Subscribed !!!! LOL Thanks for posting videos I can Learn From ...
thinking the job thru, not just doing the job [as in not fighting rounded bolt heads] reminds me of how you fell trees, intermittently standing back and re-evaluating! preserve self, money and time! good vid.
another job well done ! good idea pumpin' that shaft out with grease. taking them bolts out might have led to heartbreak, frustration and possibly abject failure.
Maybe you could try air to push that piston out and save your grease for adjusting the tracks. You might have to rig up some pipe and a small valve to do it safely, but I think it will work. I've done it with lift cylinders on a Cat 988 A.
not a bad idea, but one thing to be careful with that idea is that since air is compressible, it can rocket a piston out of it's bore. grease or oil would not do that. Either way, i scooped out the grease and re-loaded my grease gun with it! Thanks for watching!
themadmailler That's why you need a small valve so you can control the volume of air you put in it, or use a blow gun with a rubber tip, then you can shoot some air to it and then pull the rubber tip away from the hole which would then bleed the air out of the cylinder and stop the piston movement.
I have the same dozer. My track tensioner is seized. When I try to pump out, grease comes out of a relief hole opposite side to the intake. I’m thinking about welding shut the relief hole. Any ideas?
If you weld that hole shut you'll never be able to relieve the grease to loosen the track. What is likely happening is that the ball is not sealing at the bottom of it's hole. The bolt that holds the ball down may be too short or the ball may not be there.
I just bought a 350B and have no experience working on heavy equipment or any equipment for that matter ... I really am learning from you and would love to hire you as a consultant (if possible). Do you have to break the track to do this job? My left adjuster has a 2" piece of angle over the shaft to hold tension on the track.It goes from the back of the shaft housing and the center support/roller. I have not tried to use grease to keep tension and remove the angle yet because I am afraid that it might make the machine inoperable. I bought it as more of a toy than for doing work and would like to replace all the worn out parts giving it a fresh lease on life.
Most likely, that angle iron is there for a reason. If the track is at a good tension, leave it alone. A lot of old equipment has half ass repairs for a reason. In this case, it is because you need to break the track to fix the tensioner. It's not a horrible job, but if you don't rely on the machine to make money, I'd leave it as it is until it becomes a problem.
@Daniel Elliott link is approximately 6 inches c/c. Adjuster seems to have close to 8 inches of travel. I was also thinking of having the new adjuster rods made up an inch shorter.
Derrick Rees John Deere was a great farmer/General contractor machine. As far as serious earth moving, Caterpillar and International were the kings but you paid for it big time.
@Jeremy Shanahan keep looking it's the only one. I have one kind one side and a different one on the other. No mistaking that those are the ones to pound out.
I have just machined new adjuster shafts for the family farm's JD 350-C. I'm a machinist so it was easier to order new hard Chrome shaft and whip up a new pair vs buying parts. I made up the tapered cone and fitted the seals using the lathe. It was nice to have but still one tough seal! Link to an album below. My grandfather bought the dozer new in 1978 and we are just fitting its first set of new chains/rollers/sprockets. Not bad for 40 years of farm work. photos.app.goo.gl/5uPRJScqhU2hd5ht5
Local machinist is using the same material for my machine. Approximately $340 canadian. 2.5 hours/$110. I'll be way ahead of JD money. Having issues locating after market idlers and rollers.

Great! Glad I can help. Enjoy your new machine!
Very good. I probably won't rebuild my 350 adjuster myself but this was very helpful in understanding how it works.
thinking the job thru, not just doing the job [as in not fighting rounded bolt heads] reminds me of how you fell trees, intermittently standing back and re-evaluating! preserve self, money and time! good vid.
Thanks for doing this video! Have to do this on my 450D and seeing it done is so much easier than reading the manual.
Awesome! Thanks. Glad I was able to help out.
You have the part number for the kit?? Both of mine need rebuilt unfortunately
Very interesting. Thank you for posting.
another job well done ! good idea pumpin' that shaft out with grease. taking them bolts out might have led to heartbreak, frustration and possibly abject failure.
Ziplock bag with ice and salt helps SHRINK shafts. May be minute but every little bit helps. (Chilled shafts, lubes, etc.)
It's been verified that having the cup in boiling water helps .
Nice tomorrow i am doing one.thank for the video
I want to thank you for these video's.
You're welcome, thanks for watching!
Where did you buy the parts? HW wanted a lot more than $120 for the piston.
@@mlauntube I think I just found it on ebay.
@@themadmailler Thanks!
I have a 350c. Where is the best source for parts. The Brandt dealer is very very expensive.
very helpful...thanks for the video!
Very nice job. You might could have soaked that ring in hot water. Softened it a little before pushing it on. Looking forward to more videos.
Great idea! I'll do that with my next machine.

Can this be taken off and repaired and put back on without separating the track if it was unbolted?
I'm not sure, I don't think so. I guess it can't hurt to try, worst case, you'll have to break the track anyway.
Does anyone know where I can get a piston and yoke. The grease barrel and the shaft. I’m needing the ones like in the video.
HW Part Store sells some new ones that are high quality!
nice job
Looks like kind of like a neoprene seal. Put it in some boiling water and soften up to seal. It will go on a lot better.

Chavis Nicholls fins a small ball bearing that fits in the whole it’ll plug right up and you can push it out. That’s what I did.

What was the site that you Found the seal and ring from
Broken Toys. Just shipped me two sets. Super pricing. Approximately $20 each.
Is it feasible to remove one link out of the track?
No. It will be to short. One link makes a world of difference
@Daniel Elliott link is approximately 6 inches c/c. Adjuster seems to have close to 8 inches of travel. I was also thinking of having the new adjuster rods made up an inch shorter.
What sort of grease do you use in the tensioner? High temp? HIgh pressure?
anything will work.
Nice can’t wait to see more!
Waw that is great for any Mechanic. thank stay bless
Great video thanks for sharing 👍
thanks!
Those John Deere Parts are impressively hefty and strong . Would you say that their stuff is/was better quality than most ?
I don't have much experience with machines of this vintage and size, so i cant say. Sure is beefier than my Deere MC crawler though!

What does Cat mean? Can't Afford That!
Aloha...good job
Where do you separate the track?
At the master pin.
Can you describe the master pin or email me a pic of it please?
if you look in my Dozer playlist, i actually have a video detailing it's removal!
Ok thank you! Ill try to find it.
