1948 B1B Clutch grinding

[Guest chopdr230]

Hi there this is my first posting . i recently purchased a 1948 1/2 ton B1B the motor had been recently rebuilt and runs like a top the clutch and throwout bearing had also been replaced but when ever i press the clutch pedal it makes a grinding noise and the previous owner said the shaft was worn and if you rotated it the noise would go away ???? Dose this sound right and what shaft ? have any of you run in to this and if so is there a permenant fix ? Also i removed the rear end and put on a ford 9 in becouse it was cheaper than buying new drums so i have a 48 rearend laying around if anybody needs one its located in peoria il i wouldnt ask much for it i just dont want to scrap it if some one needed one for an all original build . Thanks AL

Welcome Al,

Is the grinding noise happen while you're pressing down the clutch pedal, or the whole time your holding the clutch down? If it's just while the pedal is moving up and down, than it's probably a worn bushing and shaft where it pivots. That makes it rub on the floor panel and makes noise. If it's grinding the whole time, that usually indicates a bad throwout bearing.

I thought it might be the trow out bearing but the guy i got it from said he just replaced it . i guess i will have to tear in to it and see what is going on . Can you get a good look at the throw out bearing by pulling the bottom of the bellhousing off or do you know any other tricks / Thanks AL

Does it make this noise when the engine is not running?

If it grinds -makes noise only when clutch pedal is pushed all the way down-improper flywheel bolts/assembly would cause noise, especially after a rebuild or engine swap. Learned this through experience.
