Does anybody do this? I am installing a saginaw 4 speed in a 261 using a 48-53 bellhousing and a 10 inch clutch and the matching 261 flywheel. I just had the flywheel turned and the clutch and pressure plate are brand new.
I just can't believe how you are supposed to get these things within .008? Really? This is 1955 technology! How many of you guys really check this, or do you just slap the flywheel, clutch and pressure plate back in?
How critical is this and how critical is it to shim the flywheel?

If there is misalignment, it will cause wear on the input bearing and improper mesh of gears. I have seen people who mounted flywheel housings that were warped in a fire and the transmission would jump out of high gear when he they let off the gas. I think this is probably one of the most ignored check to spec things there is in light vehicles. However, with the over the road trucks I have operated for over 45 years, dialing in the bell housing is just a way of life. | | |
