Re: Help. Saginaw problem.
Yes, reverse points up, 1-2 & 3-4 point down. In fact, by having the shift levers on the shift forks, this will hold the shift forks in place on the cover and aid in installing the forks onto the synchro sliders. Don't force the cover into place.
Turning input shaft in neutral, output shaft may turn because of friction from the bearings. Not a bad thing, a hand on the output shaft will stop rotation.
Do shift the trans by hand on the bench while turning the input shaft and view/feel the output shaft turn at a different rpm. Make sure the trans works before going into place. A Saginaw is heavy on the chest, cast iron case & tailhousing, underneath the car and going up into place. It does help to have the clutch plate centered about the flywheel and pressure plate. You want the trans to meet/touch the bellhousing before bolting the trans into place.
Using two long, 4"-6" cheap bolts with the heads cut off can be guide pins. Check the fit of the input bearing retainer into the bellhousing for proper fit.
Have you changed anything inside the trans?
Good time to change the rear seal to insure it doesn't leak along with a smooth yoke, emery paper on the yoke?
