ISO torque spec for rear diff pinion shaft pin bolt...

ISO torque spec for rear diff pinion shaft pin bolt...

I've got a FSM (the new fancy one, can't find my old one), but I'm having trouble finding where the torq spec is for this bolt/pin...

#12 on this pic
.

I put red thread lock on an tightened it pretty hard with a stubby ratchet, but I'm hoping to find the torq spec before the red thread lock set up,

I don't want to just gorilla it, because the old bolt cam apart when i used it to level the pin out... so i don't think it's very strong...

any help is appreciated.


thanks,

Cal/Eric-

I don't recall red loctite being called for on the pin and it might make it near impossible to get out in the future.

 

[caladin]

i was just being paranoid since it's inside the diff and hard to get at... I was able to pull it after using redlock to reassemble

should i put it and use blue instead?

Thanks,

I believe the torque is 12 ft/lbs but don't hold me to that. Go to the FAQ and look at the torque specs in there. It's buried somewhere

FSM says 181-325 ft-lbs. minimum is 181 ft-lbs., maximum 325 ft-lbs., keep cranking till you get within the range of 7.8-11.3 in-lbs of preload torque on the pinion.

This manual is the most difficult to find specs in as they are not listed anywhere but in the procedures themselves which is great for using the manual step by step but it provides more torque specs then any other I have seen.

Doh, didn't think about the FAQ been to long since i did anything on it...

According to the FAQ

Differential Pinion Shaft Pin 14 f/lb

Misc Torque Specs - Use at your own risk! (FAQ)

Thanks for the knock upside the head!

[Rock40]

I believe he's talking about the small retention bolt inside the differential itself. It's only an M8x1.25 bolt I believe and the torque spec on that will be very low. You're thinking about the pinion flange nut.

 

[Stephen Hancock]

I believe the torque is 12 ft/lbs but don't hold me to that. Go to the FAQ and look at the torque specs in there. It's buried somewhere

I read 110 fp. I used that. Hope I didn't over do.

 

[Shark56]

I read 110 fp. I used that. Hope I didn't over do.

If you are talking about the same Pinion shaft pin bolt then 110 Ft/lbs is way too high! It should be around 12-15 Ft/lbs.

My mistake< Talking about parking brake transfer out put shaft bolt. 29MM
