John Deere 870: 440 front end loader will not raise up or down.

Mon, 27 Mar 2023 14:55:35 -0700

My 440 loader on my JD 870 tractor suddenly stopped going up or down. The cylinders are trying because it will move about 1 inch. I checked and added fluid but still doesn’t work. The John Deere store said it is not necessary to bleed the lines. What else should I look at.

John Deere 870: Injector return line leaking

Wed, 07 Dec 2011 19:13:05 -0700

A small hole developed in my 1999 JD 870 injector return line and fuel leaks out even when engine is off. Plastic line, curves along top of engine. Guessing a mouse chewed the hole. I notice the line is in sections. Area affected is about 7-8" with clamps on either end. Can this simply be replaced with a substitute length of line? If so, what are the specs? Suggested removal and replacement tips?

Thanks.

John

John Deere 870: Lift will not go down.

Lift is stuck. In raised position. Oil level is fine. Shaft from lifting lever ( right side) to linkage control lever ( left side) seems to be working ( not broken, connected properly, etc.) Many loose and chewed or cutwires. PTO works fine. Any ideas?

John Deere 870: What is the part next to the fuel distributor with oil cap?

There is a part just to the right of the fuel distributor/pump? that has a yellow oil cap on it.

I cannot find this referenced in my manual and it look like it needs oil. What goes in there and what is the level? Also what is it?

Thanks.
