The voltage regulator should not keep it from starting. Take the wire off the generator armature terminal, that should isolate the regulator if it is bad. I would say unhook the battery wire from the regulator, but I am not sure if the switch is tied to the regulator for power without digging out a ...

Are you looking for a "blueprint of the track frame that would show all the hole locations and thread sizes? If so, that would be something you would have to ask your JD dealer if they can get it from John Deere. Between finding some of the old holes and the holes in the crossbar you will most likel...

Any updates?

Coarse or fine thread?

Thanks for adding the info, it may help someone in the future.

I am thinking 5/16 or 3/8 may be fine or coarse thread.

The way this has gone for dtoots1, I expect we could hear of both.

Good. What next?

Sorry, the C was poor eyesight on my parts. The same applies to the 450E steering. If the oil pressure is not on the steering clutch piston the steering clutch is released. Oil flowing freely from a hose into a pail, may not froth as it can when being forced out of a seal or hole in a hose under pre...

Sounds like a hose/fitting is bad or clutch seal is leaking. Those clutches have oil pressure anytime the engine is running unless you pull the lever to stop that side. Then the pressure is dumped off the clutch pack and the brake applies. Foaming would indicate oil flow that should not be there to ...

Generally, yes as long as the valve spool is centered and blocking flow to either side on the tilt cylinder. Try it. You may see a little leakage if the valve is bypassing a little and some from the cylinder as the blade moves which it will not having oil held on both sides of the tilt cylinder pist...

kmdfarm, You would be best served to start your own thread about your 440. Right now, the thread title is 450B parts in Vermont. You are offering a different model machine, at an unknown location. You will likely get more interest in a separate thread where you tell what your 440 is. The 440 could b...

Test it with the wires unhooked from the generator. The field contacts in the regulator ground the generator field to control generator output.

This old Delco bulletin may help you.

Delco Remy 1G-150 Bulletin

The original was a Delco Remy type A. Grounding the field terminal of the generator will give full output. To polarize the generator use a jumper wire and flash between the Battery and Generator (armature) terminals of the regulator. Or use a jumper wire and flash power to the generator (armature) t...

My thoughts are that you can be sure everything is free to adjust, and you might be able to get it close. However, when it is on the ground and reacting during travel any play in things will react differently than when it was suspended without weight and friction reacting on the track frames, idlers...
