TRD S/C Maintenance How-To

Haha, thank you anyhow.
I was thinking start with 20nm

 

Make it 15 foot lbs. Once it stops turning give it a turn 1/4 to 3/8 torque past.

 

Just be careful @Sterling_vH111. After all, the entire blower is aluminum, and soft aluminum at that. If you torque too hard you could pull threads, or worse, even crack the nose assembly housing and that's the last thing want.

To put into perspective what I am talking about I did an oil pan install on an LS2 once. Torque spec called for 10 or ft lbs. Of torque for each bolt on the pan in a sequence, which I did to a T because I DID NOT want leakage as the cast all aluminum pan was stupid to get to. Upon completing the install with just 2 or 3 bolts left, I was tightening one and heard a nice crack sound out of that section of the oil pan. Luckily it was on the edge, where I was generous with the silicone and the bolt was already on, so I stopped and moved on, it never did leak, but my point is that NEVER should had happened, especially because I was following FSM tq spec.

The reasons above and the inherent industry- wide switch to aluminum engine blocks and accessories is the reason why I don't trust that torque spec bullshit.

 

Fair point — I always feel uncomfortable without a torque spec, for the exact same reason you don’t like to follow them lol
I’ve accidentally stripped stuff by overtaking them, but never when I follow the torque spec.
I left them a 15 foot pounds, as thats what I felt they were close to when I took the bolts out.
Ty for the help!
I am stoked to get this supercharger & a few other go-fast-parts on my truck! It’s been pretty much all stock oem in this aspect for its life!

 

Good stuff. I'm glad it worked out for you.

Torque spec for me is okay on steel to steel applications like wheels and lug nuts, and the other sections I mentioned above, where YOU KNOW they won't skimp out on the build quality and material surface area. It's almost impossible to break a wheel unless they are that cheap. I'll leave the FSM spec values for the rookies (Who I theorize the values were targeted for, specifically the day 1 guys at dealerships not to point any fingers).

 

Wish some one would just make a stud kit instead of these bolts.

 

The valve cover bolts snap pretty easily also. Luckily I was able to remove mine cfrom below after the top snapped.

 

the bolts holding down the fuel rail are easy to snap to if going to Torque spec. broke one when swapping everything from one motor to another.
