Gearbox overhaul

Roger,

You indicated that we may need shimming, Bellville washers, a shaft bearing/oil seal. Do you have the part numbers handy for 912 ULS? Also, can the slipper clutch be taken apart by me and cleaned without taking it in to have it done?

As Roger said (many moons ago), "you will need a few special tools and it would be better to let someone do the work that has done one before. You need a hydraulic press, and a couple of special tools to get the shaft in and out."

If it were me, I'd just remove the gearbox and send it out to someone who's done a lot of them before.

Unless you have the proper tools and have some training from a Rotax class I would just send it in. You can cause problems and if re-assembled wrong could totally trash your gearbox. You won't be able to service the clutch yourself.
