Torque conversions
 

My Hayne's manual for my fc gives most of the torque specifications in psi, which is wierd to me since that's a pressure, not a torque. Anyways, my torque wrench only gives torque in foot*pounds and kilogram*meters, so how would I go about converting? I've searched for hours on google and gotten jack.

Something is wrong. Like you said, psi is not a torque, but a pressure. All values of torque should be in ft*lb or N*M. Why don't you check the FSM online?

These values should be correct. I also find that the FSM is more helpful than the Haynes manual.

Can you gives us for what fastener you're looking at?
It might've been a typo in the Haynes manual - there are a few of them in there.

Most of the torques are listed psi for some strange reason, I guess they thought a home mechanic would be using an air gun able to take up to 400psi. The fastener in question is the oil pressure regulator in the front cover. I tried tightening it to the specified psi, assuming the psi was a typo and broke the thread. The guy that fixed it told me that it shouldn't be more than maybe 10 ft-lbs, instead of 85.

I'll just use the FSM for numbers from now on, and the haynes for technique and good diagrams.

That particular part (front OPR) is spec'd at around 30 lb-ft.
I wouldn't even use that spec, cause I had mine fall out once, and I used a Snap-On torque wrench on it. :(
I now back the bitch on with an air gun, cause I really can't afford those things to be falling out.

Maybe you're looking at the bypass pressure spec?
That sounds more like 85psi as a reasonable number to print.
