Re: 1996 850 rear hub torque specification, updated, two different nuts used, change in 1996

Post by RickHaleParker » Tue Oct 09, 2018 4:44 pm

Found this in VIDA. Vehicle profile set to 1996 AME 850.
Information type: Specifications, mechanical.
Search all for "Rear wheel hub" you should find it.

One thing Volvo is infamous for is: midyear production changes that are not uniform across the production plants.

Jim Bee: What is the thread size of the shaft end?


New nut for rear wheel hub

A new nut for the rear wheel hub will be introduced into production on all 850 models.

Factory Code: Model: Chassis No:
1 854 1219646
1 854 2221178
2 855 2121509


The introduction of the new wheel hub will result in the following changes:
The shaft end thread size has been increased from 20 mm to 22 mm.
New, self-locking nut with 22 mm thread.
The new nut is re-usable.
Note! The rear wheel hub threads must be oiled before reinstalling the nut.
Tightening torque for the new nut is 120 Nm (89 ft.lbs) + 35°.

I think the P80 designation was used up to 2000 for the V70 chassis and 2005 for the C70

I missed your post above, Rick, it got caught in the electronic binder as I turned the thread page.... :-)

I’m happy that my intuition on reusing the nut was good!

I am going to check on something this morning.

The rear nut may be one of these Volvo self locking with a metal shoulder inside the thread, in which case my re-using it is a really, really bad idea.

The inspiration for this was that I came across this with the P8- ball joint retaining bolt/nut. Its not really high torque but the nut has a soft metal shoulder that locks it in place.
