About three years ago I started to make a new pressure plate for my Panhead. I didn't mount it that year, then had an accident that made a complete rebuilt of the Panhead necessary which took almost one year. Last year I drove it as it was so...I finished and mounted it today as part of the seasons preps.
All started with a drawing:
Machining of the counter bracket for the coils (10):
I bagged them because this one and the pressure plate itself will be send to a local shop for giving them a nice black anodization:
Special nuts made of titanium (because I like the dull finish). The holes will be for the locking screws (M3):
Drilling and milling of the pressure plate:
Almost finished, only turning the cone needs to be done:
Finished and sand blasted:
For fitting I made a nice little helper which enables me to compress all the springs and take the complete assembly to fit onto the clutch studs:
Aluminum (7075) parts back from anodization:
Complete assembly with springs, nuts, everything...
Pressed in a threaded bushing:
Compressed the springs, ready for mouting it to the clutch studs:
Assembled like a charm with only one minor flaw: finding the nuts position to tighten the locking screws was a bit tricky.
