Tranny input shaft play
What is the maximum amount of play that is allowed for the input shaft of the tranny? I searched the FSM but could find nothing. just shy of 1/32" but it seems to be a bit much. Then again the shaft is fairly far out and there would be the pilot bearing supporting it.
Just want to know before I go through all the trouble ya know, thanks much.
Probably should mention.... S5 TII tranny... thanks

As in none at all, solid as a rock kinda thing?
I don't think changing the cover will help as it shouldn't make direct contact with input shaft.
Anyone know for sure or should I call one of the abundant shops up here on the east coast?

well you adjust the end play simply by thrust bearings (washers). Standard thrust play is 0 to .1 mm or 0 to 4 inches. Adjusting shim thickness .1mm(0-.004 inches) or .3 mm. This is for the mainshaft, but same thing. You might want to double check on this but i got the info from www.alldatapro.com. It's a website we use for about everything at my college.

I asked the same question here with no answer just before my last rebuild went in.
I had quite a bit of play, and less than 20,000 miles on it since trans front cover was replaced.
I just went ahead and put in the motor as I didn't expect the motor itself to last long. That was 20,000 miles of racing and daily driving ago- half of that on race tires ~400hp.
I checked my J-spec's transmission and it has play as well.
Sadly, i will be checking my trans shaft play again as the motor finally died by eating an EGT sensor probe (stuck side seal now).

I never saw a spec for allowable play, but any time I change trannies (far too often) I just buy a new front cover (Which includes the bushing) from Mazda Motor Sports and throw it on. IIRC, they run about $20-$30 and well worth it for the peace of mind.

Wow, thanks guys. I learned something new. I was unaware that the frontcover actually plays a part in the play of the tranny. Will definately order one. Are there shims as well that can take some of the play out? I wasn't seeing those in the FSM
BlueTII I did see that thread you started when I searched, good to know that you managed 20,000 miles and still going strong. Thanks a bunch guys.

OK, so I'm lazy. I can admit it. I consider a degree of laziness to be a sign of intelligence.
