ring gear torque

I recently started a re gear. I haven't even got far and already have questions. Here's what i got. Motive gear and usa standard master install kit. So I just bolted up my ring gear to my new carrier. Motive gear instructions state ring gear bolts to 55 to 60 flb's. So I set to 58. No biggie right. Well as I go digging through the rest of my parts I noticed a bag of bolts that must have come with my new carrier. These bolts are the same size and grade as my master install bolts. Right on the bag it says torque gear bolts to 75 to 85 flb's. 55 to 60 seems to be correct from research. Am I ok? Over thinking? Should I pull the bolts and replace and re torque using the other bolts?

What size are the bolts?

Both 3/8 and 7/16 are used.

3/8. The thing is both sets of bolts are the same size and grade. Only difference is one set came with the install kit and the other with the carrier.

Did you apply red locktite?

Go by the specs given by the gear manufacturer, not the carrier. My gears are Nitro, their spec is 55 ft/lbs. That's what I did and they've been fine.

I just changed the ring and pinion in my Jeep today. The FSM said the D30 torque to 80 FT lbs and the D44 torque to 100 FT lbs.

Agree... When I did my locker in my D30 the specs were to tighten the ring gear bolts to 80 ft lbs.

Yes on locktite. This seems like s logical answer.

Yep there are two sizes of ring gear bolts, only use the higher ft.lbs. figure with the larger size bolt. And DON'T FORGET the Locktite on the ring gear bolts!

When you have a choice, buy American made.

The FSM is wrong. Well I know atleast for the D44 it is. 100 lb-ft is way too much for the size of bolt used. There are people who have sheared them at less than that.

From what I've seen when looking through Spicer's information, 50 lb-ft is used for 3/8 and 75 lb-ft for 7/16.

This is straight from the FSM

Dana 30
"Ring Gear Bolt . . . . . . .95-122 N-m (70-90 ft. lbs .)

Dana 44
"Bolts, Ring Gear. . . . . . . . . . . . 108 N-m (80 ft. lbs.)"

I think you probably misread the D44 spec.

When you have a choice, buy American made.

I also cleaned bolts and holes with acetone before locktite and toeque was applied. I generally have a good feel when tightening bolts and wouldn't think these particular bolts would make it to 80.

Jerry, I think some of the FSM are printed incorrectly. I've seen the torque specs he posted in them before. Either way its wrong and the bolts should not be tighten that much

Torque specs differ depending on the threads being wet or dry and wet with what.
