I do it by feel and have always greased my bolts (mainly at the shoulder) as I've seen bolts 'welded' into hubs in the past.

Thats because if you use a torque wrench for anything other than hub carrier bolts and head bolts you are a ... I'm learning aren't I slindy

We do mine to 110nm. 90 is too loose I think. Undo that with my hand

[slindborg]

Note its not the bolt on its own that holds the rim to the hub.... its the combined clamp of 5 bolts

I was talking with a techie from Nordloc just the other day, Torque is all about friction, so if you put copper grease on you would need a little extra torque, say 5 nm more Having said that I am sure there are large safety margins and no doubt most of us over tighten when we do it by hand, which is fine as long as you don't go past the yield point of the bolt

The Bosch Blue automotive handbook has a list of Lubrcants VS thread pitch tables for increasing the torque values if you so desire.

I've always added a little copper slip after having a bolt weld itself to the hub. If 90nm is finger tight mine are alot tighter than that. Might just stuck with what I'm doing until I hear of someone stripping a thread.

i do 100Nm, given that most torque wrenches are around 10% out.

mbes just reminded me, remember to throw away the lock nut and replace with standard bolt.

100-110nm. 90nm gets loose on track with my TD's

you haven't had yours calibrated? I'm shocked

[haggi961]

90Nm on mine and also copper grease on the ends and ive never had any problems on mine.

Don't forget there is a correct order to tighten them as well!

My small one is calibrated, rated up to 50Nm, the big cheapo one isn't

[starlight]

The handbook in the Europa says 110Nm. They are the same bolts and hubs... Although the paint shop that did the front end managed to tighten them to over 200Nm...

A quality torque wrench should come with a calibration certificate. Mine is accurate to ~3% across the whole range

At time of testing.
