: I am experiencing a screetching type noise coming from the area of the pilot bearing. At least, that is what a local mechanic who knows Model "A"s and modern cars says. This noise is occuring spasmodically and is heard only upon breaking and slowing to a stop. I drove the "A" today and it did not do it! This is typical. The noise is not big problem! I just want to be ahead of the game on this one!

: The clutch is fine. No problems! I gave the throw out bearing a squirt of grease about 120 miles ago, careful to not give it too much and get grease on the clutch plates.

: The mechanic said to go ahead and drive the "A". It would not hurt a thing. I explained that this "A" had not been driven for quite some time. He said that this was one of the reasons I was hearing it. The mechanic said to just drive it around town for awhile and see what happens.

Ans: The pilot brg is in the flywheel and it supports the front end of the transmission input shaft. That's the shaft that the clutch plate is on. The pilot bearing only turns when the clutch is disengaged. Thus, it is a small sealed brg. If you have noise with the clutch engaged, it ain't the pilot brg. Disengage the clutch (pedal down) and if it screetches it is either the throwout or pilot brg. You can see and feel the throwout brg by removing the top floorboard and opening the inspection cover in the bell housing. Manually rotate the throwout brg to feel for roughness. DO THIS WITH THE ENGINE OFF. A bad pilot brg is not serious but is a big job to change it for such a small item.
