Hi, Has anybody had a problem with the turbo 400 hub bore diameter? I just got one and it will not fit the shaft like the ford one; it seems that its about .004" too small. Thank you.
The hub is a press fit. Check the shaft for burrs etc that might be giving a false reading, also recheck in more then one place and if you have them use a micrometer rather then slide calipers.
The fit should not be over .0001-00, at .002-00 you will skin the shaft. It should work fine at .000-00.
.003-00 and .004-00, your going to wreck something.
Just so it isn't loose.
Erick: Yes I have had the same problem,If your measurements are accurate, send it back, a 0.001 inch interference is all that is usable. Brad from N.H.
