Project started
December 2020,
See the CAD version here
When I bought the Panhead motor there was a broken piece
of bolt in the left crankcase. It was too short to weld to,
so I carefully drilled a hole in it hoping to extract it but
it would not budge. I ended up installing a Helicoil as the
original thread was not that great. |
Next job was offsetting the inner primary (as the transmission
was also offset to make room for the 170 wide rear tire) I started
by machining a spacer from some scrap aluminium, the first try
was too thick but after installing and removing the primary
several times I had it where I wanted it. I then roughed the
visible machined surface by coarse gritblasting so the texture
was more similar to the crankcase. |
I had a half inch offset insert for the front pully, which
was way too much. I made a copy from Delrin that had the same
thickness but a less tight fit than the insert so I could quickly
figure out the required thickness. After installing the belt,
measuring and removing again I had the correct thickness figured
out and could machine the metal insert.
|
I probably will not be using this stock clutch, because they
suck haha. Now that the belt and primary are all lined up and
installed I can start the next project, which will probably
be making an oiltank from scratch. |
