Check your ground, then I may run a hot feed direct from the battery and see if it makes any difference.

 

Thanks for the suggestion. The motor has two wires coming out of it that go to the relays. I think that the relays just switch the polarity on these two wires to change the direction. So I'm not sure where the ground actually is. I don't think that it is grounded through the motor housing. Do you know how this is grounded?

 

I have no idea on ground, what color are the 2 wires coming from the motor?

 

I connected the battery directly to the motor and it was still slipping. I took apart the gear box and then the clutch. Turns out that the clutch is worn. It has worn grooves in between the pockets where the ball bearings reside.
For reference for others: The Resistance of the motor is about 0.4 Ohms +/- 0.1 Ohm. This makes sense since it is supposed to draw ~30A from 12v.

 

Thanks for being proactive and posting the motor resistance.

Any chance you can post pictures of the worn items?

 

Had the same thing happen to my 6x4 and the same failure. You have two choices for replacement that don't involve JD. Northern Tool offers an actuator, item #74280 that is a direct fit and has 1100 lbs of dynamic load capacity. On sale now for $120. Other than that, do a search on ebay for an actuator with an 8" stroke. I bought one for $65 and it works perfectly with plenty of power, but sloooow. I've used both of these actuators and they wire in exactly as the original. Easy fix at a fraction of the money. Good luck.

 

That is a great hack... If you don't have any lift installed at all can you just get this actuator and do your own wiring or is there other parts needed?

 

Yawn, yet another member asking for help and we respond. Wouldn't it be nice if he could at least acknowledge?

 

I didn’t ask the question but I appreciate your responses as I learn more about my machine.
