Are JD 350 rails supposed to have a step on the outside?

I'm looking at a used JD 350 crawler.
The track rails have a step on the outside, is this wear, or is there supposed to be a big step where they fit between the rollers?

Thanks,
Al

If I understand your description correctly I think your looking at the pin boss which is a step up from the surface that rides on the rollers, however the pin boss is not supposed to touch the rollers if it is the undercarriage is worn out.

Gatractorman,
Thanks for the quick reply.
If I understand you correctly, there is a step down, or more correctly inboard from the pin boss. And the heigth of that inner step should be tall enough to keep the pin boss off the roller?

Thanks allot,
It is great to have a source of information before I make a bad choice.

This JD 350 has the clutch stuck, will not disengage. It seems to me, the easiest way to get to the clutch would have been to pull the motor, but the previous owner started to unbolt the rear differential and the gear box directly in front of it. Unfortunately, he also broke off some of the bolts, so this part of the job will have to be finished.

Can you even get to the clutch by removing the drive train behind the motor?

Do you have to remove the tracks to get the differential out?

Thanks,
Al

If it is a 350 with a reverser it doesnt have an engine clutch....The steering clutches are located on both sides inboard of the final drives...what exactly is stuck ?...sounds like you should maybe buy a tech manual...

Thanks for the reply Jonathan,
I haven't purchased the dozer yet, but if I do, I certainly will get a manual.

I don't know if it has a reverser, the guy selling it didn't say, how would I tell?

But I don't think it does.

He said the clutch is stuck, it won't disengage, but he can start it in first gear, and the drive clutches seem to work, because I saw it turn both ways, then he shut off the engine, put it in reverse, and started again to back up.

Any info is appreciated.
Al

If it has a reverser, there will be a lever on the left side opposite the blade control.
If I start mine in gear I need to press the left foot pedal down. (clutch)..
Pressing that down disengages the motor from the 2 steering clutches.. No matter if the levers are pulled back or not..
My JD manual shows a main clutch unit irregardless of a reverser..

Thanks Mike,

Can anyone answer this:?

Try pouring boiling hot soapy water on the clutch. Take the starter off & pour it in through that hole. This has broke a couple of stuck clutches loose.

The 350's with a reverser have no engine clutch..There is a pedal that disengages engagement pressure inside the reverser....The coupling between engine flywheel and reverser is a plate with springs on it thats is referred to as an isolator...I worked at a Deere construction equipment dealership for 16 years and saw plenty of reverser equipped 350's but never one with just the engine clutch...I might recommend continuing your machine search as I believe after a short amount of use you will be totally unsatisfied with a dozer, (or is it a loader?) that you have to shift gears to reverse direction...And to answer your question...the engine clutch would be accessed by removing the engine...it is relatively simple to get at..

Jonathon,
Thanks for the info.
Its a dozer.
Is the reverser the unit right behind the engine?
I will try to find out if this dozer has a reverser or not.
So could it be that the reverser is stuck and will not disengage (assuming it has one)?
Thanks,
Al

OK,
The guy says it does NOT have a reverser.
Does this mean this machine is not worth much, especially since it is in need of repair?

It runs good, and the pins have been turned, I THINK the UC looks pretty good, I am obviously no expert. The tracks do seem a bit loose.

So its a JD 350 manual angle and tilt blade dozer serial #T4F1C 0942511 3 cyl gas. Some of the bolts holding the front of the differential to the gearbox are broken, and the clutch is stuck.

Will be allot of work to fix, any rough ideas of how much $$ its worth?

Thanks,
Al

Hey Al, I've been keeping up with the discussion and since this machine starts, moves and steers its worth something but I'd be afraid to say how much (the gas engine killed it for me), I've never saw a 350 that didn't have a reverser but I never saw all the 350's that were made either, if you do get it and it does indeed have an engine clutch put the blade up to a big tree or something its not going to move let it sit there and spin while you hold the clutch pedal down most times that will break it loose.

...yes...try that clutch freeing maneuver....as far as price is concerned...the more you describe it the lower the price goes in my eyes....Gut feeling tells me you should pass...gas engine...no reverser...mechanical blade...you will hate it to operate...

Thanks for the advice guys,

I basically agree with you, but consider this.
I own about 42 acres, and only want the dozer to work on building a road and a homesite for myself. I know the manual blade and lack of reverser are negatives, but I won't be making a career out of running this machine. It is tough to find anything decent here in Ohio for under $8000, and this machine is now less than 1/2 that, but it will have to come down more.

The problem with your method of breaking the clutch loose, is the fact that the differential is no longer bolted to the gearbox in front of it (transmission I assume), and that box is also unbolted from the unit in front of it(which must be another gearbox?). Some bolts are broken off, so this must be repaired before putting any heavy strain on the machine.

Thanks again for the good advice!
Al
