There are two guides that come with the kit.The first is to drill the crank and the second is threaded to guide the tap.
These i think are to ensure that the hole is drilled and tapped horizontally.
Wow...Having to drill a perfectly centered hole in the end of the shaft to a precise depth outside of some sort of fixture is a real challenge. Even under the best of circumstances drills have a tendency to wander a small bit. An amazing job to have to do.
Just thought i would give an update of the supercharger fitting.
I spent half the day drilling and tapping the thread for the crankshaft drive pulley.It is something i would not want to do again although
i am really happy with the end result.TTS forgot to mention the use of the bottom tap in the instructions but that is why 2 taps are supplied
in the kit.
Trying to work out how the new clutch lifter piece is fitted,no mention in the instruction.
