: 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.

Ken, I agree with the various responses to your question and would add this one comment.That bearing also can cause difficulty in shifting gears without scratching.If the bearing is not frozen, only very tight, it will cause the main shaft to continue turning when the cluth is released.Rotation of the flywheel is passed through the sticky bearing to the front shaft even with the cluth released, causing it to continue rotating.This is condition is noticed more when the car is not moving, cluth depressed and attempting to shift to low or reverse gears.A little gear grinding will occur.Years ago I tore down a Model A and found a oil impregnated bronze bushing serving as a pilot bearing.As far as I know there were no problems with it.
