I recently started tearing my 1973 904 apart and when i took the oil pump out a small steal ball bearing rolled out, i read the manual that is linked on this sight and it seems this ball goes on the input shaft kinda shoved in there..and to top it all i lost the ball today , does anyone know an easier way to describe the location of this ball and it would be GREAT if anyone could tell me the proper size...

Did you check the 7 digit part # to be certain it's a "73 trans? I've rebuilt about 20 904s and never had a check ball fall out of a pre-78 non-lock up trans.I took apart a '71 S/6 front pump just to double check before I wrote this,and they DO have two check balls in the rear pump half,but they are staked in very well.I could describe it to you,or maybe photo bucket it to your e-mail,but check those numbers first.
