input shaft end play I just got done building my transmission. I have a concern though.
I shimmed for 0.0015" end play for the mainshaft
0.002" preload for the countershaft
and 0.002" end play for the countershaft extension.
what is worrying me is how much the input shaft moves radially... you can see in the video below that despite the input shaft moving radially so much, the end play still measures to 0.0015"
do you guys think i should reopen my fully assembled transmission from the front plate only and reshim and change the shim to bring the total end play to 0.000"?
why does tremec recommend 0.000 to 0.002" end play on the mainshaft? the only logical reasons i can think of are: 1. increased lubrication to increase bearing life, 2. to allow a little bit of misalignment of the input shaft due to manufacturing tolerances.
i really don't want to open the front plate if i don't have to cause i used "right stuff rtv" and it's a pain to clean
