For LFS and KFS, among others.
Sachs original number 1028510-7018 or 0286 206 000
Number 16 on the exploded view.
NOTE, if you have one with 22 teeth, you must also change the worm drive to 11056 or knock off the 24 teeth variant and replace with your old one.
Also called main shaft or output drive shaft
All of these that are on the market right now have a problem, the attachment for the drive on the shaft is a little too large. Either you have to grind a little on the drive or a little on the shaft. New ones are coming but maybe only this fall. There is only one manufacturer on these. We choose to sell these anyway as the problem is easily fixed, and otherwise there are none at all.
