I removed the rotor head to install the tachometer sensor. I ordered a bracket from GBA and was surprised that the magnet was 90 degree clocked from the SH1 plans.
However, in the SH3 plans it is correct so this is what I used.
I also replaced the bolts with bolts with castle nuts.
I replaced the bendix gear I broke on the pre-rotator and pinned the bendix drive shaft. Interesting enough is the fact of the hole in the bendix drive shaft is off center and the pin can not go completely through.
