TRIUMPH T150 T160 BSA ROCKET 3 TEFLON PISTON PIN BUTTONS SET
(6 PIECES)
These buttons are a direct replacement for the gudgeon pin circlips on the pistons.
It used to be a racing modification which had the following benefits:
-Reduced friction between pin and Teflon in comparison with the circlip.
-With the standard circlip there is always the possibility of breaking, destroying the cylinder
bore. However Teflon buttons will never break or wear out.
-Easy press-in installation.
Teflon can withstand temperatures up to 300 Celsius degrees.
From their inner side they are hollow in order to reduce weight.
The weight of one button is 3 grams.
ATTENTION THEY ARE DESIGNED TO FIT ONLY WITH HEPOLITE PINS (THE ONES WITH THE TAPERED BORE ON BOTH ENDS)
NOT SUTABLE FOR THE PINS THAT ARE SUPPLIED WITH EMGO OR JCC PISTON SETS
THAT USUALLY HAVE A STRAIGHT BORE.
They are made on the following sizes:
Standard
0.020 oversize
0.040 oversize
They can be made and on other oversizes on request.
So please when buying specify what size you want otherwise I will send the standard set.
