Well, since in your other post you were talking about bleeding the clutch to cure a noise in the thrust bearing, I would say you have very little mechanical knowledge.
But I don't know you, I can only go off what I've read in your posts, and what I've read suggests to me you aren't qualified to tackle this particular job.
So, based on the information I have about you, I would suggest take it to your mechanic.
Mick.
