Triumph factory part number D2213 or 60-2213.  

This tool is absolutely essential to remove and replace the cam gears of all Meriden Triumph twins through 1972.  (Not suitable for T140, which uses a simpler bolt puller.)  The two threads of the cam gear re-fitment bolts (shown on right) will cover both early and late cams.  Fit and finish guaranteed perfect. 

Includes small camshaft plug, not shown.

I will answer questions promptly, good luck and thanks for looking.
