OPERATIONS – installing new spline to ring-gear

The ring-gear/spline is mounted to our lathe to machine away the factory weld.
Next we heat the assembly in our oven to 350 deg F.
The heated assembly then goes to our press where we chill the internal shaft and press off the old spline.
The ring then goes back in the oven and heated to 350 F
The ring gear in its heated state is ready to receive the new spline. The spline is pressed in place and held under pressure until it reaches room temperature
The final step , we weld the spline to the ring gear like as it was originally done at the BMW factory.

    Working on my first project, an ’81 R65, the splines were about shot. Had difficulty finding a local shop in Sydney that would do the work. Called up Osh, spoke on the phone for about 20 minutes, sent a few photos, and he weighed in that it was about 75-80% to tow truck time…

    Shipped over the final drive, Osh and Co did a great job. Came back vapor washed and looking amazing. Osh also recommended replacement of the driving dog as well for the rear wheel. In the absence of a shop to do the driving dog rivets, Osh provided the shoulder bolts. Everything mounted and bike runs smooth!

    Thanks for the great work.
