125/200/fs1e type swingarm bush.
« on: November 24, 2010, 06:35:14 PM »


Rubber cushioned bushes make the rear end feel spongy,  (reminds me of Ford Cortina Mk4+Mk5 void bushes).





Here is a solution I cooked up for my FS1E project to solve the problem.  This will work for the RD125/200 also, but dimensions and bearing sizes will not be the same.  (I will sort the 125/200 bearing problem when the shed gets warmer in the evenings).





Here are the basic parts:-

 Each requires 4 bearings. At about ?6.50 each, (can be done with 2 bearings and central spacer on the cheap), plus bits of scrap tube I had in the shed and some black nylon66.  







Pic of stock tube before and after some lathe work:-









Fit some bearings, 4 in this one:-









press in some nylon or oilite end caps and machine flush:-













Fit spacers to suit:-









And here we are:-









The end result:-











Just showing off for now,    



And for those Fizzy nuts out there, spot the missing hole in the "new" chainguard fixing bracket.

Hopefully my compound bearing should eliminate this.
