Do you need a press or any special tools? The bearings in mine are beginning to make noise.

Well, it says "We suggest the rebuilder have access to a set of snap ring pliers, and a small arbor press, in addition to standard shop tools.".

So there's the answer. thanks buddy!

I rebuilt a Saginaw 4 speed at the auto hobby shop on Miramar when it was a NAB. Not that bad to do. They had a shop manual I used. You can do it Luke.

As far as I can tell so far, synchro rings are not available for the SM420 (in case they are needed). Novak notes on their site that they hope to have them available in the future.

Some minor googling, will bring up other sources for synchronizer rings.
