Title: g5 inner clutch body and thrust bearing
Post by: guzzig5 on April 12, 2015, 12:46:07 PM

78 g5 clutch inner thrust bearing in pieces and the inner clutch body looks worn or broken ? I can't seem to get the outer race, bush and push rod out . has anyone taken the end plate off with the swingarm still in place ?

DO NOT  try to remove the rear transmission cover until the transmission is removed from the bike.

The shafts will drop out of the bearings and then you are stuck

Top part is worn flat and the end looks sheared .

Yup. And if the thrust bearing was in pieces you have no idea where all the bits are.

Time to pull the gearbox and go through it.

One of the races/washers of the throw-out bearing with lots missing?

The inner race of the shaft bearing?

I don't think you'll find out what it is until you remove the tranny and take the rear cover off.

The shaft bearing and the needle thrust bearing were both in pieces in  an Ambo tranny that I rebuilt.  I couldn't determine which one failed first.

It really doesn't matter what it is, the trans needs to come out and apart. Then you'll know.

IMO, the main reason for release bearing is, improper free play adjustment. So many times I get bikes in with the cable so tight that the release bearing is always under load. It won't last long like that. Also, the clutch lever spring on the rear of the trans is often missing.
