Jeff's 727 rebuild thread

I got the valve body finished with the shift kit.....
Thank god for digital cameras!
Had to do a little drilling here and there and file this notch...all in all not too hard...

Started moving on to the sub-assemblies
Used my new press tool. ...worked great. But I did put some little c-clamps to hold the ears in the snap ring grooves...

Gonna start pressing bushings today...

A couple of questions
My tailshaft bushing has these notches (2) at one end...
What are they for and how do they align in the tailshaft.
Also, what is the little window for?

Also, what is the purpose of these 4 check balls on the pump?
