RIDING A 1974 BMW R90/6 FLAT TWIN
FORK WEAR, LEAKY NEW SEALS... AGAIN?
Fork seals giving trouble and starting to leak after being replaced just recently?
New seals and still oil coming out.......
Pop the seal with a special tool, a piece of soft wood.... or your thumbs
Fish out the crimp spring
Now anybody who ever played around with miniature Wilesco steam engines
as a kid recognises these items immediately. Similar springs were used as
drive belts for miniature tools such as drill presses, sawing machines and
the like. These '' belts " were custom sizeable, by the kid. So here we go!
The spring has a joint, at ten o'clock in this photograph
Unscrew anti clockwise
Better use a toe nail clipper instead of this! and cut about a cm off and remount.
The seal becomes a slightly tighter fit now and probably does the job just fine.
The forksliders could be worn out as well giving excessive play, making
life tough for the seals to hold back the fork oil. Also in that case you
might be helped out for a while longer with the above little trick.
