When you reassemble the LC tank how tight should the screws be that fasten the aluminium tube holder to the tank.

I have looked at the Advanced Procedures but there is no mention as to how much torque to apply and I don't want to damage these.

No idea if there's a torque setting, but hand tight is fine. I know that's vague, but more than snug, less than massive hand force.

Guys -

I googled around and had a hard time finding a mapping of screw-driver/nutdriver torque as a function of "feel". According to NASA, the max is about 10 ft-lbs (13N-m) of torque in supination (clockwise) turning of a T-grip bar and wrist motion. For a screwdriver, I'd bet it is a bit less. I did find a cool mil-spec document (1472G can be free download here). The largest value torque on a screwdriver I found is 70in-lbs or about 5.5 ft-lbs...so I'm guessing my thinking about the NASA thing is about right.

Anyway, I think it goes:

*Just tight
*Snug
*Firm hand pressure
*massive hand force
*push-down with one-hand-turn about hard as can with other
*do all of the above and grunting while hoping you don't crap your pants
*get the impact driver

I usually make them snug, not overly tight, but tight enough.

None of the screws on the LC tank need ot be very tight. If you over tighten them, you will either damage the silicone gaskets, or make it impossible to save the gaskets when you disassemble in the future.

Thanks Guys I get it.

Firm enough so it doesn't leak.

Get the half inch cordless impact wrench out, rattle the f*** out of them til something breaks, then do them all up to about 1/50th of that. Or just hand tight
