Violent Take-Off Shudder

Bad shudder was always pilot bearing in my experience.

Loose pilot bearing ^^^^ clutch disc goes off center, shudder, shudder, shudder.

Could have been wrong size pilot bearing upon assembly. Should be able to pull the clutch inspection cover and look at the position of the clutch disc between the flywheel and pressure plate. Then rotate by hand 180° without stepping on the clutch and check again. 3 /16th" off on the 2 checks is a lot.

That is a seriously bad shudder you have there, something is seriously wrong.

Should be able to have the shift in neutral, idling, clutch and trans quiet as a mouse.

Noisy loud exhaust does not favor trying to listen for clues.

Ever put the clutch disc in backwards????
