BMW airhead Transmission, 5-Speed Gearbox. Fully Serviced 1981 to 1995

Description

This is an 1981 BMW a transmission.  It has been completely gone through, with five new bearings and all new seals.  The shifting cassette has been updated with a bearing roller to replace the old plastic one. The output shaft has a circlip. The neutral switch has been tested and works as it should.  The reason it is shown opened up is that this type of gearbox can have two different output seals.  If it is for a GS-type airhead with a dry driveshaft, it gets one type of seal.  If it is for a bike with a driveshaft running in gear oil, it gets a different one.  When a buyer gets this gearbox, he or she can tell me what sort of bike it is for and I will install the correct seal, measure the gear clusters, shim the clearance and close it up. If you have a gearbox with problems, I I’ll give 0 trade for the old box.
