Torques for sprockets

[mylovelyhorse]

So I've just had a very pleasant few hours in the garage replacing the chain and sprockets on my 2012 F800GS. I went for the F650 front sprocket as advised.

So I don't know what torque to do the front sprocket nut or the rear sprocket retaining nuts & bolts to. I feel done them all at 50 Nm for the time being but if that's well wrong I'm ready to get the old torque wrench out & re-do.

Does anyone know the correct values?

Gearbox sprocket 50Nm with lock tight
Rear axle nut 100Nm
Rear sprocket to carrier, new nuts'n bolts 10Nm then 90 degrees

Gearbox sprocket 50Nm with lock tight

Check

Rear axle nut 100Nm

Check (that one's in the manual)

Rear sprocket to carrier, new nuts'n bolts 10Nm then 90 degrees

Ooh I've done them up way to tight. Oh well, don't suppose it'll kill them.

Hey could be worse, bought my lovely new (yet to be paid for) tourqe spanner off Amazon. Then following day needed to remove the flywheel off my Kawasaki, give you a clue similar drive side.
Outcome torque spanner sans drive in the bin even before the invoice arrives, missus says whats this for.........
So thats we do in our man cave ! When we dont understand the first principles of engineering!

They're not torque spanner's ... they're torque wrenches, you use them with sockets ... not spanners

You're right of course, you, not we, don't understand the first principles of engineering

I had my torque wrenches calibrated by a nice man in a van yesterday. I was very impressed that my old Norbar which must be 40 years old was still within tolerances as was the slightly newer Britool. That, kiddies, is why you should always release all the spring tension on your torque wrenches when you're not using them.

Good advice Mike ... but what about Torque Spanners

They're more correct than torque spanner's.....

Would anyone have a suggestion of where to calibrate in London?

The guy who did mine left me his card. He works for these folks - http://www.calibration.biz They're based in London but if you contact them a man in van will come out and meet your calibration needs.
