Diff drain and fill plug torque? (1 Viewer)

[CharlieS]

Does anyone have the torque specs handy for 80 series differential drain and fill plugs handy? I've searched Mud and the FSM, and must be using the wrong search terms because I just can't find them.

Which ones are you using? I’m using the magnetic, hex-head and it’s 39-ft lbs for the front and rear diffs. Edit: looks like it’s the same for the regular plugs.

Looks like 49 N*m

I've never used a torque wrench on a drain or fill plug though, you're supposed to replace the crush washer every time you pull the plug and I just go by "feel" to when the crush washer crushes and then stop.

Google works better. Thought it was mid 30s, 39lb seems most commonly listed. Slightly less for tcase, mid-high 20s. Don't stress it, get 'em snug is good enough, just don't overdo it

till it's tight it's not holding anything just a seal

Thanks all.

FWIW, and for future reference, all the relevant torque values are listed in a table in every section in the FSM.

Thank you.

I tried searching by kewords in the fsm, but didn't find it. I know it is a me error, not a fsm issue, but I often have trouble locating things.

Oh, and to answer the above question, I am using the original style 24mm hex magnetic drain and regular 24mm hex fill. I bought new ones to start fresh. The onea on it had clearly been attempted wirh a 12 point socket and were worse for the wear. I realize some people prefer the internal hex/allen style, but I am happy with the original.

Don't forget to loosen the fill plug first !

 

[CharlieS]

Aye. Always. I am baselining a new to me rig. Fill plug first, drain plug next. Six point socket only. New sealing rings/gaskets/crush washers.

Used my favorite trick with a plastic hose and the compressor to fill. So much easier than any other method
