727 Rebuild Blues

Sal_Detroit1 said

Hello guys. Don't want to hijack the thread but I cant seem to find anyone with this much knowledge on the 727. I'm also rebuilding one for the second time and this time around I don't have the book with all the specs. Do any of you know the end play and the clutch pack clearances? Keep in mind this will be for street/strip use so if there is tighter clearances that should be used for that application what are those also?

Any help is greatly appreciated!

I shoot for .015~.020 end play. Sometimes you'll end up using the thickest selective washer (the one on the back of the pump) to get it tight enough.

.035~.045 clearance for the rear clutch pack. Some guys claim they go as tight as .030 and I tried that on 2 and both wanted to creep in neutral a little until the clutches wore in a little.

.060~.085 for the front pack. If your front clutch pack has 8 springs or less and the front band apply lever ratio is 3.8 or higher you may want to set the front clutch clearance on the loose end of that range otherwise it may have some 2-3 shift overlap.

Make sure and air pressure test things before you button everything up and install it. Air pressure testing can save a lot of future headaches.

BTW: here's a link where you can download the ATSG rebuild manual for torqueflites for free
