Chaffin's book on the rear axle does not give a value for clearance between the hyatt bearings and the sleeves (inner or outer).
My Hyatt bearings are good (all within spec) however when you slip them in the sleeves (axle not in yet), there's a fair amount of clearance (the outer sleeves are almost new).
So, is there a clearance figure or just snug fit, loose fit, generous fit ?
you will need the axles in to feel what clearance you have.
You need the axle in place to push on the Hyatt rollers, then the rollers will contact the inner sleeve surface.
If the rear end is apart, it's a good idea to check the housings for straightness. 9 out of 10 of them are bent!
Bud, The bearing clearance is a big variable. The problem is the axle housings. The holes where you install the sleeves vary in diameter by at least 0.020 in.. I have the figures that I have measured but can't find them now. Some bearings are tight, some are loose. Apparently Ford didn't care. You can mix and match to get the fit you want. That's your only choice.
Straight housings - the only thing that was OK on this rear end rebuild!!
Thanks for the info. With the axles installed, everything seems pretty tight
All buttoned up now - just the U joint pin to install!
Put the bearing on the shaft with a hose clamp and measure it in several places, The measure the ID oh the race. Don't be surprised if theres .020 - .040 difference from one end to the other...
