CB160 upper shock rubber bushings
Posted: Fri Aug 03, 2012 7:01 pm
Since the rubber upper shock bushings are now made from unobtainium, I decided to make my own. My left side had turned into black goo but the right side was good enough to get dimensions.
Well it turned out to be much easier than planned. I thought I'd have to grind them on the lathe with my mototool. But it turns out Goodyear 1/2 ID rubber hose has a 3/4 OD. The mounting stud for the shock measures 0.495" and the ID of the shock is 0.790".
So, the standard Goodyear rubber hose sold in hardware stores works like a champ. For the flanges on the end of the bushings, I simply cut rubber disks from an old inner tube with a 1 inch punch. The new bushings fit like they were made for the shocks. 1 foot of hose is $1.49 so I probably have enough left over to make bushings for everyone on the forum.
regards,
Rob
