Nissan Patrol 4x4 (Africa)

Hi guys .. dunno where else this should be .. Please advise if you know. Tell us if you guess.

A LOT has been speculated and said around the NM of Torque the wheel of our NISSAN mu8st be tightened

I think there could be a difference between the flat faced STEEL rims and the Magnesium and Aluminium Wheels

Please share what you know??

Malcolm van Coller says that he learned in his track racing experience that the mag wheels should not be torque more than 65 .. else they crack.

Hi Oom

The manual states 118 - 147Nm for steel rim wheel nuts.
Seem like a lot.

This from the manual

Found this on magnesium wheels.
133Nm

One cannot simply compare a small, light mag from a track racing car to a heavy-duty mag found on a 4x4.

The concept of torquing a bolt is as follows: any material, when loaded, has a deformation. The first part of this deformation is called elastic deformation, which means that, if the load is relaxed, the deformation also dissapears. Thus, the item has not "bent". If one continues to add load, the material will enter bend, or deform permanently. This is called plastic deformation. But even then, when the load is removed, the material will return slightly toward it's previous dimension.

Now consider a bolted joint. The nut is effectively held in place by the friction between it and the face it screws up against. Thus, if the load is removed, it can vibrate loose.
Thus, the bolt has to be loaded to a higher load than it will be subjected to in service. Otherwise, during service, it will be loaded to a greater extent, and as soon as this greater load is released, the nut wil loosena little bit, and soon it will be completely loose.

Thus, the torque is determined by the size and material of the bolt, not so much by the material it is holding down.

So, the torque specified in the manual is irrespective of the type of wheel.

Which is why the 133Nm above is dead in the middle of the specified range...

OOmpie ..ek trek alle wiel boute tot op 110nm en het nog nooit een verloor op gestrip nie

Ek het ook dieselfde vrae gehad oor my karavaan se wiel boute. Ek het ook advise van 110 Nm gekry. Ek het bietjie gespeel met 'n torque wrench en om dan die bout met 'n wiel sleutel vas te trek. Daai 110 Nm voel maar soos wat jy die boute sal vas trek soos normal. 65Nm klink amper of jy dit net met die hand sal vasdraai
