You can add a little lead substitute if you want. You likely aren't going to put on enough hours to cause much valve recession. Octane is a waste of time on these old girls, probably 7 to 1 compression maybe.

Re: JD 440IC Steering Clutch Adjustment
If at 1 1/2" the throwout just begins to move outward, it is an adjustment issue with the connecting rod between the steering lever shaft and the throwout quill. If the adjusting bolt is at the bottom of the slot (farthest away from the pressure plate), then yes, the discs are shot. Unless you addre...

Re: JD 440IC Steering Clutch Adjustment

Re: 440 back firing
Timing can not jump on these barring a mechanical failure of some sort.

Check all connections, check polarity on coil and anything else you can think of. Then for kic...

Re: Cracked housing repair
They are cast iron, vee it out, braze it and run it. There is no concentrated stress on the hole, it is distributed around the hole by the bearing quill. It is likely a crack from prior in it's life when a bearing went out and played nutcracker with the gears, and cracked the case. Normally it just ...

Re: Grease in Rockshaft
I can't see it hurting anything, but better make sure it is full, and coming out past the seals or you won't have any grease around the shaft.

Re: Devcon for sprocket/final drive shaft repair
I'm assuming you mean between the hub and the axle? If so, I'm also assuming you have a 3 roller crawler?

Re: Need pictures of back of 1010 crawler loader hydraulic quick connector for backhoe
If it is a hoe capable crawler, there will be 2 large lines coming from the diverter near the valve body. If it is not a factory hoe crawler, there will be no lines or diverter.

Re: Roller Grease

I've been out of the office a lot due to a death in the family, but have 14 hours of road time every week, so just leave a message, and I will call on the way back home.

Re: identify my 350 injection pump
Part number should be on the pump.
None of them come with the window, it is only installed for timing, then removed.
