How to convert a 1960-1969 BMW motorcycle
hydraulic steering damper
to a friction-style damper
by Craig Vechorik of Bench Mark Works
Reasons why one would want to change a hydraulic steering damper to a friction damper:
1. The complicated linkage system of the hydraulic damper has developed excessive play due to wear and it has become ineffective.
2. The hydraulic damper cylinder has leaked oil and is no longer functional. (The cylinder is not currently available as a replacement part.)
3. You wish to fit a sidecar on a BMW motorcycle that has a hydraulic damper. The change to a friction-type damper is very important to allow for proper steering adjustment.
The actual removal and installation of parts is easy and very straight forward. See the parts diagram that follows. If you need further assistance, call me at (662) 465-6444 10 a.m to 4 p.m. central standard time and I'll be glad to talk you through it.
