clutch install qusstion
i've installed lots of chevy clutches, but this is my first flathead clutch. 59 motor, '39 trans, rebuilt 9" clutch & pressure plate, new pilot bushing & throw-out bearing. when i tried to slide the trans in , it wouldn't go all the way in. still needed to go about one half inch more, so i used 2 longer bolts to force it in, then tightened the regular bolts. was this a bad idea? or is this normal? thanks!

Re: clutch install qusstion
My guess would be that the pilotbearing to mainshaft was either not alined or you had problems with rust on the axle going into the bearing.
Did you test the bushing on the axle ? |

Re: clutch install qusstion
i test fit the pilot bearing on the trans first & it fit perfectly. i installed the pilot bearing by hammering it in with a 2 x 4, maybe that warped it a little bit ?

Re: clutch install qusstion
It should go all the way in without force. If there is a problem with the throw out bearing or clutch cover fit, it may have disengaged the clutch when you tightened it up. I'd take it back off and check your clutch control stuff and pressure plate cover. Most of the clutch alignment pilots, even though they are plastic, should be a slip fit with the pilot bearing.
Where did you get the clutch components? |

Re: clutch install qusstion
My experience has been that if you use first use a clutch alignment
tool the transmission should slide right in. "Forcing" sounds like a bad idea. Can you remove the transmission inspection cover and see what happens when you depress the clutch and shift the gears. |

Re: clutch install qusstion
It will turn out to be a simple problem, but you really have to take it apart now. You can not wait. It is not going to work in the present condition.
Just my opinion |

Re: clutch install qusstion
Good you figured it out. Be careful with longer bolts forcing it up. You can break the transmission housing doing this.

Re: clutch install qusstion
no, it's not in the car yet. but i thought it was a good idea to put a light coat of grease on the splines for the clutch to slide on. what do the rest of you guys do?

Re: clutch install qusstion
Should be dry , when its all aligned properly it should just slide on.

Re: clutch install qusstion
alignment is key. Horizontal, vertical, and rotational.
With a new pilot bushing it may fit tight but if these three factors are aligned it will slide in. Look at the surfaces of the disk where the input shaft indexes. If they are shinny it may indicate a rotational misalignment. When you used long bolts you forced the rotational alignment. As others have said, remove it, clean it, and reinstall the transmission without grease.
