Project started
December 2020,
See the CAD version here
In the previous episode I figured out that the transmission
needed to move 9 mm to the left to allow the chain to clear
that big rear tire, so I made a CAD design and sent it off to
CNC, when it was finished I wasted no time installing it and
yes, the chain is straight and clears the tire. I am not shortening
the chain yet as the position of the transmission will be clear
when the primary belt is installed.

In the meantime I continued putting the Panhead engine in
CAD, I scanned the heads and almost finished putting the lower
end in CAD. When that is done I can put the real lower
end in the real frame.: |
There is something about my frame that has been annoying
me, there is an extra bend in the seat area that annoys me and
the seat area itself, as on most Harleys, is way too big for
my taste. A bit of surgery is in order, more about that (in
the CAD version first) later this week. I have started with
making a bending template for the replacement frame sections
|
Having changed my plan from a Shovelhead to a Panhead motor,
and having moved the transmission 9 mm to the left, the primary
belt will require some modifications. I bought a Rivera/Primo
1½" belt drive. The front pully is a 2-piece construction
which will make it easier to line up the primary belt. I will
probably use a tin primary on this bike. The 2-pieces were not
easy to separate, I heated the whole thing up in the oven to
soften the Loctite and after the screws were removed I used
the lathe to press out the center. |
