Charlie,
  Suggest getting a winch from Harbor Freight and mounting it on the 
front.  Will email you a photo direct as the forum kicks them out.
It's 12VDC and 2,000lbs so it can be used as a winch too with 50' of steel 
cable.

Subject: (ET) Further front lift disassembly woes

I thought I'd just peel off the plastic coating that the motor assembly 
was dipped in at the factory, but it hung on like grim death
- it's not coming off without solvents.  Instead I used a knife and 
whittled away enough to get a nut-driver on the long bolts and then cut 
around the casing seams.

But I still can't get the guts to come out... basically I have a
one-inch gap I can peer into.   I can't figure out how to release the
worm gear from it's housing, either, and the worm acts like its cut into 
the end of the shaft rather than being a separate part.  :(

Do both ends of the casing come off?  Like, does the end plate that has 
the electrical connector come off after the bolts are loose?  I haven't 
had any luck with it, but I could always use a mallet on it if it's 
supposed to come off.

But after blasting out the couple tablespoons of black powder I can see a 
set of contacts that look like they're probably held together by a 
bimetallic spring, presumably a thermally controlled voltage cutout?
 I can also see that the brushes are about as thick as a piece of paper, 
and the commutator is deeply grooved.

If I can find an affordable newly made or NOS replacement for this motor I 
should probably replace it.  Otherwise I guess I'm going to be whittling 
some new brushes...
