Re: Power assist cylinder rebuild

Thanks...I gotta pile of parts that resemble a dozer. Figured I would do some detail work while it's apart.

Re: 450C near death accident

Man, I hate to hear this. It is life changing, but you can certainly make the best out of every day. We all have different challenges we face each day. I recently had a battery blow up in my face and it was over a silly mistake.

Thanks for sharing.

Re: 350 reverser

Gonna start answering my own questions...lol The orifice is two parts and both can be removed with a short flathead screwdriver. The needle valve comes out first and then the orifice. Pretty easy job to remove and clean. Also I was able to get my pressure up to 90 psi and the reverser worked great. ...

Re: 350 reverser

I was able to raise the clutch pressure by adjusting the orifice out...took 4 complete turns but I got my pressure up to 75 psi. They're may be a clogg in the orifice. Anybody ever clean one? I saw where gregjo asked the same question. The service manual says to tighten the orifice "in slightly". I ...

Re: Jd350 track tensioners

Yeah that's a relief hole. You need to loosen the lock nut and tighten the set screw(bolt) down until its snug. Then tighten the lock nut. The lock nut is preventing it from closing the gap. While you're at it make sure you have the steel ball under the set screw. Probably have to take the screw out...

Re: shims for reverser

Thanks for the info Jim!

I wonder how much an .024 shim will help the pressure. I'm currently getting 45 psi for the clutch oil regulator valve.

Re: shims for reverser

Forgot I had a parts book...

T15858t .060 thickness
T14587t .024 thickness

I done a pressure test on the clutch oil regulator valve....it was only 45 psi.

Re: 350 B steering clutch

The left side clutch doesn't seem to disengage...can't coast backwards. Previous owner had a make shift tool to measure the pressure plate fingers. Tool looked good, but I'm unsure how close he got them adjusted. Definitely explains how it could slip, but I think both sides would be adjusted the same.

Re: 350 B steering clutch

That's makes sense, but what about disengageing the clutches on a hill and letting it roll backwards?

350 B steering clutch

I know they're a bunch of steering clutch post and I've rebuilt several myself, but wanted to get some input. 1974 350 BE SN 196047T The right side steers perfect. Clutch disengages and brake locks seamlessly. The left side had to be adjusted because it was absolutely non responsive when the stick w...

Re: Purchase questions

My 350 has a lever to engage the winch drive. The spool valve also has a neutral or float setting so I don't have to power down the dozer.

Re: 350 reverser

Yeah it has it's own hydraulic system. The previous owner states that the large o rings (piston rings??) were not replaced, on either clutch assembly, when he rebuilt the reverser. He feels like when the fluid get hot is bypasses the assembly and looses pressure. Moves perfect when cold and for abou...

Re: 350 reverser

Old post here, but I'm getting ready to take on a 350 B with this very same issue. Are the mentioned suggestions working for you guys?
