View Full Version : PTT worn splines

I don't know the correct term, but the "groves", "splines" in the discs are GONE!!! that's why my clutch went out..... everything else was perfect, but seriously, they are smooth almost no groves what so ever.

I guess I will just order some new ones from PTT

How in the heck did this happen? and how to avoid it from happening again?

Well, $200 shipped for new clutches, I could have spent $60 ea to be re-hubbed........... nah, just go new.......... so, not too bad I guess.

There was also somthing to do with the bearing in the trans that would cause this to happen. I think there is a bearing that has a higher tolerance/less play or somthing like that. I would look in to it befor you just throw the new ones in.

The bearing "issue" is a red herring.

It's PTT trying to place the blame on something other than their parts.

That's why my new set of discs are Quarter Master and not PTT.
