Let me think back... I had an ST4000+. I'm trying to think. It may 
have had grease on the rollers. If so it almost certainly was 
silicone grease. I'll check. I'm sure I have saved info on that wheel 
drive, but we're not at boat-home now.

One thing. There is an adjustment for the belt. There's a black 
plastic cap on the motor side of the drive. I think it's near the 
motor. When you remove it, there's an allen adjusting screw with a 
locknut. The locknut is flat and has two holes in it for a special 
tool. I used a right angle long nose pliers. It's a trick to adjust 
so that it doesn't disengage randomly on one end, and it doesn't drag 
when disengaged on the other end.

I wound up buying an old Simrad pilot, with the external belt. the 
motor checked out the same for no-load and stalled current. I 
connected directly to the motor, bypassing the drivers in the motor 
assembly. That was the end of the problems with the wheel drive. I 
now have an Raymarine S1 with the wheel drive II. They finally got it right.
