I am assembling a motor with the M3 tensioner, which did not come with instructions. Looking for help from someone that might have istalled this or had the instructions included with the tensioner.
The pivot pin at the bottom of the tensioner is an extremely tight fit. Should I open up the holes so that the tensioner actually pivots around the pin, or should it just rock back and forth on the rubber inserts at either end of the pin? If I leave it tight, is seems as though any misalignment during the installation procedure would be maintained due to the extremely low tolerance (It takes quite a bit of force to get the pin in), resulting in the cam chain rubbing on the inside of the tensioner, and possibly not sitting in the groove correctly. Also, it seems as though I should install the spacer that is used in the stock configuration. I know the tabs would need to be ground off, but the spacer is still too wide to fit. Is this something that should be left out, or should I throw it on the lathe, and trim to fit? I'm sure that the tensioner will hold up, but I'm surprised about the quality of the machining and rivets. Just seems a bit hacked to me.
Thanks
