I have a 67 beetle stock everything with a new clutch disk and a new clutch pedal (the original broke). Since I put the engine back in I get a high pitched squeal when the clutch is fully depressed. I have adjusted and readjusted the clutch and it has about 3/8 of free play. I canít figure out what I am doing wrong. Any ideas? I really appreciate the help.

67 beetle sedan
1500
Stock trans, original cable, new pedal disk and throw out bearing.

Bad throw-out bearing.

Probably a defective throwout bearing as noted, but since you said the squeal doesn't occur until the pedal is fully depressed, before you tear back into it you might want to increase your freeplay first to see if that stops the squeal; you may just be overcompressing the pressure plate. Your 3/8" freeplay is just under the minimum spec laid out by VW.

If it is in fact the TO bearing and you are somewhat talented then it is entirely possible to take it apart clean and repack the bearing. I donít know what a new aftermarket bearing costs now but I do have more confidence in a genuine German bearing.

This seems like a good suggestion since I'm assuming the squeal wasn't present before the new clutch was installed.

Thank you all for the information. I will readjust the free play and hope for the best. The squeal wasnít there when my Dad garaged it in Ď86. Iíll post an update when itís dry enough outside to get greasy. Thanks again and Happy New Year to you all.

I would squeak too if I hadn't moved in 34 years! Wink

Did you only replace the clutch disc? Not the pressure plate and TO bearing? Typically they are replaced as a set. This is to avoid having to remove the engine just months later because one of the old parts failed.

You should also consider resurfacing the flywheel so that both sides of the clutch disc have a fresh/clean friction surface to work against. Just make sure the machine shop knows what they are doing. The stock VW flywheel needs two surfaces resurfaced to maintain the proper distance between the clutch surface and the mounting surface. Unlike some cars which mount the PP to the same flywheel surface that the clutch disc rests on, ACVW flywheels have a ledge for the PP to mount to.

Hi All. Thanks again for the awesome information. I readjusted the freeplay and the squeal went away. I am going to pull the engine in the early spring to replace the front engine seal and will get the pressure plate and flywheel surfaces machined. I found a garage that is very old school and knows quite a bit about the old Beetles and has the skill to make things right.
