I have a 93 rx7. I'm about to pull the transmission and was wondering how many bolts are there holding the bell housing to the motor. I count 5 and read up which mentions 5 but there appears to be two on the top. The issue I see is that I only have only one on top. I'm assuming the shop never installed the last bolt out of laziness??
5 is my recollection without looking at the FSM. Two are close together on top. One near the oil filter and the other two at about 4 and 8 o’clock. IIRC one is longer than the others. And you need some long extensions and a U-joint for the uppers. Nothing unique about them (M14x1.25 maybe?) so it shouldn’t be hard to replace the one that’s missing. You just want it the correct length…not too long.
McMaster Carr would be a good place to check on-line. Otherwise if you have a Grainger store in your area. My local Westlake Ace is pretty good source too.
I’ve never measured. I think trident above took care of that for you. A millimeter or two short wouldn’t probably be a huge deal. But I would’nt go longer.
Thanks! I see they only have a 50 mm for tge 55mm bolt that I need. I'm assuming that 5mm shorter won't matter?
I don't think it will matter, especially if you use that one shorter bolt up top where you have two bolts relatively close together around the bell housing. With a 1.25mm thread pitch, that 5mm shorter bolt means you'll only have 4 fewer threads digging in, but depending on how deep that threaded hole is on the rear iron, you probably got at least a dozen or so threads digging in if the hole is at least 15mm deep.
