JD 440 c clutch issue
« on: January 02, 2011, 05:44:54 PM »
My JD 440c skidder is loosing power, it cannot get out of its own way.  I can only move in low gear, tires will not spin if I'm up against a rock.  Does not move when I push too hard on the accelerator, if I throttle back it starts moving.  When it stops, I move the wheel back and forth and suddenly it starts moving again. 

Please tell me it's my clutch, I heard if it's a transmission I'm screwed.  Also, can the clutch be worked on without pulling the engine?

Is it a powershift or a standard transmission? Do you have any freeplay in the clutch? Could be anything from a rear main leaking on the clutch to a clutch or powershift. If it's just the clutch it's not to expensive. I have a 540D in the shop that the powershift is slipping bad. We're thinking about parting it once we found out the cost of a rebuild.

Clutch inexpensive repair , Power-shift 5 to $8000.00 to rebuild, my Funk cost me 7200. to rebuild, a new one was $14000.00, this was 25 yrs ago.

I sure hope this isn't your case, best of luck

you must pull the motor. isnt really as scarey as it sounds. clutch pressure plate throu out bearing check pliot bearing. may need flywheel resurfaced. also a good time to change rear main seal if a lot of hrs. on motor.
