you really dont need it unless your exceeding 9.500 rpm

The current 12 pin retained rotors were made to handle 9k,.. and actually have less load on them at 9k then at 7k.

I bet that rotor was fun to chop down and make it visible to see the track. That would be about the equivalent as the plexiglass idea?

A very large Circlip or snap ring is fitted onto the end of the gear and compressed into the groove. The gear is pressed into the hole in the rotor, with the original pin holes lined up, and when the gear bottoms in the hole, the Circlip pops out and about half of it engages the groove in the rotor.

Then new roll pins are installed. Now the gear will not walk out of the hole, no matter how many revs, no matter how hot.

Hi, how do I get the old roll pins out? they are too hard to drill, an easyout won't grip

and the gear can't be levered out.

Suggestions welcome thanks

Regards

Michael

I don't know why everyone says the pins in our engines are so hard to drill? $5 carbide bit, some oil, and a drill press drilled the exhaust housing pin out quickly enough; don't see why it wouldn't work here.

Thanks for reply :-)

6mm carbide drill and drill press haven't worked for me <g> the only thing I can

try along that line is a 3mm drill for the smaller roll pin then the 6mm for the outer?

The carbide drill will do it to a point but is getting damaged and is not likely to finish the job. The pins are very well hardened.
