Author Topic: Advance & retard unit (and solid) fibre wheel replacement.  (Read 906 times)

There was a recent topic about the virtues of alloy drive gears v. fibre drive gears. This led to a discussion about replacing the fibre drive gear in ATD's and solid, manual adv/retard gears which is slightly off topic. I offered to put some instructions on my website so, for those who are interested, here it is!  Just follow the Do it Yourself link on the ATD page.

Thanks for sharing that. Very helpful document.

A lot of people would have just kept the information to themselves.
