1970's AMF Polar Bear Transmission
Original Message   Dec 20, 2008 3:08 pm
I bought a 1970's AMF Polar Bear at a rummage sale for $25.  It didn't run when I bought it, but after changing the points and the carburetor it runs like new.  My problem is that the transmission doesn't work.  After inspection, all the parts appear to be in good condition.  However, the rubber wheel is not touching the spinning metal disc that the belt turns.   If it did touch, everything would work well.  The rubber wheel appears to be in good shape.  It's not cracked and doesn't look worn, but it could be deceiving.  I'm thinking about getting another rubber wheel, but I don't know where to look.  If anyone has any information, I'd appreciate it.  The AMF model number is  13620400.

Are you missing a Large spring that drags or pushes the wheel against the drive disk?

Take a picture of the assy. for us.... We would like to see what the assy looks like..

Good Luck..

Well...I took off the rubber drive disk, thinking that it was worn out.  I took it to a local Simplicity dealer and they had one in stock.  My drive disk actually looked no different than the new one.  So...I kept my drive disk, went home and reassembled the components.  I said a little prayer, started it up, and transmission works phenomenally.  I don't really know how to explain it.  Everything appeared tight when I disassembled it.  All is well, now.   Thanks.

Things might have been too tight. That rubber wheel is supposed to swing in contact with the flat disk whenever you hold down the traction system clutch lever. If the cable isn't adjusted properly then the wheel won't contact the friction disk. It could be something was stuck and got freed when you did the disassembly.
