Re: 450G starting issue

May be low compression after it gets to operating temperature.

Re: 450 Steering Clutch Stuck

You could try bumping an immovable object (tree-boulder) with the clutch lever pulled. Don't pull it so far that you're applying the brake. That's what is causing the engine to "dog". This maneuver sometimes will break the stuck clutch discs loose.

Re: Track Adjuster installation

I don't know what the diameter of the ball is supposed to be but, you may have some ball bearings around your shop that will work.

Re: 350C engine re posted in proper forum.

Could the isolator failed and bound the flywheel?

Re: What do I use to lockout my backhoe?

Looks like the pins that are driven into the tilt part of the small JD dozer blades.

Re: 12 Volt Cap

Your compression shouldn't be so greatly different. Sounds like you might have a valve or ring problem on one cylinder.

Re: Water in oil

Does it look like it has been apart before? Maybe a dowel had fallen out and reinstalled into a wrong hole.

Re: 350 diesel running rough and smoke

Is it misfiring on one or multiple cylinders? I would think you have contaminated fuel. Drain the tank(I'd remove it and clean it) and change the filters. If the problem still exists; while it's running, crack open the fuel lines one at a time to see if the engine runs rougher. You may be able to de...

Re: JD 350

When adjusting--1st make sure the throwout bearing is clear of the pressure plate fingers--next make sure the clutch is releasing when you pull the lever--then adjust the brake

Re: JD 350

Not sure what you mean that the clutch is sticking. Are you saying the lever doesn't return forward or the
right side track isn't driving as it should?

Re: 350B steering clutch housing drain location

The 350 and 350B use dry clutches and don't need a drain plug. If you have oil
in the clutch housing, you have a seal leaking.
