Re: JD 350 INJECTOR/STARTING PROBLEM?

I would suggest two additional diagnoses. First make sure the engine can get air. A blockage may let it fire once or twice after sitting. The second is a little more difficult. Check the pump timing. If timing is off to the point that you can't rotate the pump and bring it in then you have a bigger ...

Re: Need to pull the transmission JD350C

It is possible to remove from the rear (done that) but not easy. If the tracks are sloppy you don't have to break them. Just pull sprocket bolts and lean tracks out. Will need a front end loader and helper to hoist it out.

Re: 1010 gas hydraulic issue

I assume you have a loader and not a dozer. There are probably four relief valves of varying pressure in the whole valve body. Find which section has hoses going to the bucket cylinders and then, with your serial number, go to the John Deere parts site to find the relief valve location in the valve ...

Re: Jd 350 steering clutch

Sounds like you maybe forgot that one pair goes in before the snap ring is installed.

Re: JD 450c runs for short time and stops but will immediately restart

If you remove only the return line and not the check valve then watch to see if flow stops from obstruction by mouse turds. If you remove the fitting then catch what comes out while running and look for them. They usually appear in the timing window you removed but found clean.

Re: Radiator Flush?

Go for it. But make sure you use inly distilled water with 50% antifreeze. Especially if your water has a high mineral content.

Oljoe, If I wanted to show a video of a system sucking air I would show yours. Sit on the hydraulic tank again with seat and levers removed.

Re: jd440ic charging issues & hyd cyl issues

If you have the model with the control valve on the right fender then you had better suspect the balls in the control valve too. Will never forget a service call where wandering balls totalled the pump. The plastic (or nylon) balls do wear. It dropped a little when told to raise right before the dam...

Re: Brake adjustment JD350

No. You have some other problem. Consult the parts book (PC 921) on the John Deere parts website for a schematic (serial number dependent).

Re: Battery cables overheating

Unless the cables got hot WHILE you were cranking, I would suspect the solenoid.

Re: jd440 ic hydraulic pump/hyd cylinder

Some of the systems of that era used plastic check balls in the control valve. The balls wear with time. If they wear enough to wander or stick they can total a pump. If your blade did not leak down then you had better check the control valve soon.

Re: 350B reverser

When it "won't go forward" pull both steering clutches for a couple seconds and then release them. If it "goes" then either the reverser pressure is borderline or the forward clutch pack is nearly worn out. Backing up a little gives it a short time under no load to fully engage the clutch pack.
