Service Manual, Diff/Tranny bolt torque
 

Can anyone help me decipher what the service manual lists the recommended torque to be for the the tranny and rear diff filler and drain lugs?

For the tranny, it says 34.5(3.5, 25) and for the rear diff 35(3.6, 26). No where does it list units for any of these numbers. I just want to torque them correctly for my oil changes on Sunday. Which one is the value in ft-lbs...I'm guessing the first...

Thanks

It doesn't need to be that precise to the foot pound. 1) hand tighten it; 2) using a socket wrench make it snug so that there is solid resistance without pulling too hard. DO NOT overtorque this bolt. If you strip the threads, it could be a very expensive fix. Have you ever changed your own oil? The bolt should be about as tight as that or just a little more. Make sure you put in a new washer.

Also, I just noticed on the lower part of the diagram you posted, the torque reference is right there. Click on it. However, the number you posted (34 - 35) is probably in NM given how Nissan quotes their torque specs in which case would convert to about 25 ft lbs, the last # before the last bracket.

should be foot lbs tq

35 inch pounds doesnt sound like enough...

can someone else chime in?

its 25 foot pounds, I just looked it up. However, if you have a crush washer between the bolt (I haven't been down to the differential yet) an additional caution you may want to take if you are using a torque wrench is that you may want to tighten it to make it crush before setting the wrench to 25 ft lbs to make sure it doesn't factor in the washer. If it did, you may be too loose. Doubt this would happen but just in case.

Also, while you are down there, can you take a pic?

heres the description of symbols. top two on left descibe tqs as:

Black box with white wrench = N*m (kg-m, ft-lb)

White box with black wrench = M*n (kg-m, in-lb)

so it will be 25lbs for the tranny and 26lbs for the rear diff
