Default Midwest 9" help.

Hey guys,

Well I need to slap this thing together and have a couple questions. What do I use as a seal for the 3rd member to housing and also what do you torque the 3rd member bolts down to?

Thanks,
Erik

I just used some rtv and just put a wrench on the nuts for the 3rd member. I am sure there is a torque but I do not know it off hand. I would think 25-30 would be more than plenty.

Permatex Ultra-Black rtv... no gasket required. also just use a wrench to tighten the nuts as you can't get a torque wrench on the two bottom ones anyway.

This is straight from Eric to me:
standard, plain, regular 'ol parts store 80/90 gear lube... definetly no synthetics though.

do 3 heat cycles with regular street cruising driving... no sustained highway speed or launches. after minimum 3 heat cycles, then do whatever you like. heat cycle is from cool to full operating temp, then back to cool. usually 1-2 hours cool time.

after minimum 500 miles change out the gear oil. use whatever you like and what viscosity fits your needs.

Awesomw thanks guys. And one more thing. What kind of washers should I use for the 3rd member. Fed ex or UPP or whatever delivered it with the box all jacked up and the hardware was loose. So Im missing some washers and who knows what else. Does the type of metal matter?

oh hell another question. Whe they jacked up the box they messes up the powdercoating. What should I touch it up with?

just a standard hardened washer is fine. you will need to find washers similar to the ones that were included with the package with the aluminum center due to the small counterbore around the holes. if you cant find hardened washers, some copper brake hose washers will work.
