5. Using a runout gage, locate your end mill
to be concentric with the inside of the jackshaft
housing (you may also use the jackshaft itself
to center the endmill). You can complete the
machining with the jackshaft installed if your
boring gage allows it, otherwise you will need
to remove the jackshaft. If you remove the
jackshaft, you must replace the bearings.
See the next step for the dimensions of the
machined part.
6. These are the dimensions that you will
need to use to machine your jackshaft support.
7. Using a machine press, press the supplied
10 bolt hub onto the jackshaft. The leading
edge of the hub should be flush with the end
of the jackshaft, as shown in the adjacent
illustration.
Steps 8-10 are optional. Since the
supercharger pulley is spinning at higher
RPM and driving more load than the stock
pulley, pinning the pulley is recommended
but not required. LPE pins all of their
supercharger pulleys.
8. Using a drill press, secure the
supercharger pulley so that it is clamped evenly
and drill a 3/16” hole, 1.05” deep in the center
of the end of the pulley. Next, using a 1/8” drill
bit, drill a hole completely through the pulley
and shaft in the same position. This will allow
you to remove the pin if you are ever replacing
or removing the pulley.
NOTE: LPE recommends using a hardened
solid carbide drill bit for pinning the pulley.
