Hi All, Happy New Year.

Loft conversion finished & back working on the car. It WILL be on the road this year.

I'm just fitting my propshaft & need to know what torque to use on the 4 bolts connecting it to the sprocket adapter. These bolts are 10-9 standard pitch as opposed to the fine pitch bolts on the diff end so I'm wondering whether the torque settings in the haynes manual for the prop-to-diff bolts are valid?

No it will be different not sure what though.

Torque should be lower. I torqued my rears (to diff) on 60Nm (fine pitch) and front (to engine) 40Nm (standard pitch)with plenty of thread lock. I put a line from the bolt head all the way to the washer and flange with a permanent paint marker so it aids as a visual indication on wether the bolts are coming loose. Actually i did thsi process on all wishbone, engine mounts etc.. Its a common practice used by teh Japanes on all high performance cars.

All the best for 2011

Thanks, 40Nm sounds good.

Have you got those values the right way around?

60 for fine pitch 40 for standard pitch.

If you wanted to stretch the bolts equally then wouldn't you put less torque on the fine than the standard, as the fine has greater mechanical advantage.


Just surprised.
