Syncro rings for NB 6 speed.

Do you have any experience with gearbox rebuilds? My understanding (possibly wrong) is that you have to know what your doing and have reasonable tooling to get all the preloads and fits Right?

There was a topic here a little while ago about CBC Bearings having a listing for all the gearbox bearings. viewtopic.php?f=29&t=57883&hilit=cbc+bearings

Unlikely that they'll have the rings too but at least the bearings are a start and maybe they'll know someone else who has the rings?

I rebuilt my 6 speed box at the start of the year.

MX5 Mania can get the syncro rings etc. They got me a new 4th gear syncro ring. They were reasonably priced as well.

You would buy spare parts from the usual sources. Benchmark it from Mazda. Insofar as quality is concerned the guys in the bearing industry know the better makers from the poor quality ones. One certainly would not want to put in poor quality items in a gearbox to see them fail just down the track.
