I have a 1972 904 serial pk35xxxxxxxxxx.
I am a bit confused about what thrust plates and washers go where. I assume there are no thrust plates or washers behind the rear annulus gear? Inside the rear annulus one diagram shows a thrust plate, but I don't remember there being one there, and there is a machined thrust surface already there. I assume next comes a four tang thrust washer, then the rear planetary,then another thrust washer with four tangs which goes against the thrust plate in the shell,thrust plate on the other side, then thrust washer with four tangs, next the front planetary. Then there is a fat thrust washer with one tang and a flat area on the inside that goes on the second gear planetary? If some one can verify this with a decent picture or detailed description, I would appreciate it. I have both the astgi book and Tom Hands book and still don't get a clear picture of what goes where. I have learned there have been many small changes over the years. I got the wrong tailshaft boot in a kit, and ordered a rear output shaft roller bearing and snap ring and got one that was about .060 too big! Arrr! And I measured the old one with a dial caliper for them when I ordered it. So, thanks in advance. I learn best with pictures!
