in lbs conversion to ft lbs

[94 lngbd]

I got a 7.5 rear end with out any brake hardware or a pinion flange nut for $10 will be swapping on 8.8 backing plates & brake hardware for the time being & also just welded up the entire side & pinion gears in the differential to make a locker.

Whats the the conversion from 8-14 in lbs to ft lbs as I dont have a inch lb torque wrench ,but I do have a ft lb torque wrench,would that be approx 1.5 ft lbs?

One foot pound is 12 in/lb's, so 8-14 in/lb's is barely 1 foot pound at the top end of the range. You -cannot- accurately use a normal 3/8" or 1/2" torque wrench at that level. Stop by your nearest Harbor Freight for a basic 1/4" torque wrench if you want to do this properly. With your larger wrench you're more likely to overtorque and break the fastener (or strip the threads).

For that low use your fingers... 1 ft lb... You can over torque it with 2 fingers... I can't believe anything would be that not tight but I know alot is French to be in the auto world...

What are you torquing in a rear that is asking for 14 inch pounds? 14 newtonmeter I could almost believe, but not only 14 in-lb.



Also, inch, feet. Same conversion factor as distance.

Sounds like the pinion preload on a used set of bearings. A new set would be around 20-29 in-lbs IIRC.

Yeah, pinion preload sounds like it, and that doesn't require a normal torque wrench, but a dial torque wrench.

Well, you sir are correct. Just went and looked it up.

New bearings torque from 16-28.

I've set up enough gears to have those numbers stuck in my head.

pinion preload on a used set is correct,guess i'll be stopping by Harbor Freight on Friday

Omg, I'm honored. Lmao. Someone sigged me. Awwwwww.

When ,measuring pinion bearing preload you MUSt have the proper tool.

Bear in mind of that 20-29in/lb bearing preload approximatly 1/3 of that drag is drag caused by the new seal...

This is measured by the torque required to keep the pinion rotating smoothly
not the typically much higher torque to get it moving from rest.


Most in/lb torque wrenches don't go low enough.
