TWIN CYLINDER SMALL END BUSH, "FREE" FIT (1)

TWIN CYLINDER SMALL END BUSH, "FREE" FIT (1)

PLEASE NOTE: PRICE IS EACH ie; A SINGLE BUSH NOT 2 AS THE PICTURE SHOWS.  

FITS THE SMALL END EYE OF THE EARLY TWINS (500 & 600CC) THE 650'S AND UP RUN THE GUDGEON PIN DIRECTLY IN THE CONROD.  THIS BUSH IS IDENTICAL TO T2160 EXCEPT THE BORE IS .0003" (3 TENTHS OF A THOU) OVER THE FINISHED RUNNING SIZE.  A THIN WALLED BUSH WILL CLOSE UP APPROXIMATELY HALF OF THE INTERFERENCE SO THIS BUSH IS DESIGNED TO ELIMINATE THE NEED TO HONE/GRIND THE BORE TO SIZE AFTER FITTING.  WITH A LITTLE CARE AND PERHAPS SOME HAND FINISHING THIS MAY BE A BETTER OPTION FOR THOSE WHO DO NOT HAVE ACCESS TO THE HONING/GRINDING REQUIRED WITH T2160.

LENGTH: 1"
OUTSIDE DIAMETER: 13/16" WITH A LONGITUDINAL GROOVE BISECTING THE OIL HOLE. 

PLEASE NOTE: THESE BUSHES ARE MADE TO SUIT THE STANDARD NORTON GUDGEON PINS WHICH HAVE A NOMINAL SIZE OF 11/16".
LIGHTWEIGHT TWINS ALL THE WAY THROUGH TO THE LAST 850 MK3 COMMANDO USED THE SAME DIAMETER PINS.
