Chain and sprockets
« on: November 20, 2019, 07:50:28 AM »
Coming up to the 30k service and I have a new RK Chain and sprockets I am going to fit before the dealer does the rest. Does anyone know the torque settings for the rear and counter sprocket nuts?  I have searched previous posts and cannot find them. Thanks in advance guys.  :821:

Are the rear sprockets not held on with bolts and nyloc nuts?   Just tighten them to roughly what they came off with.  The bolts are in shear anyway.

Just tighten the front one to a sensible ‘feel’ and lock it.

Rear sprocket and pinion torques.

I just happen to be fussing with my chain and sprocket at the moment.  The sprocket connections are shear load paths.  If you have a torque wrench handy it doesn’t hurt to torque fasteners considering how vibey (what’s the correct word?) the bike can be.  When I removed my rear sprocket the nuts looked like they should be self-locking, but I could easily remove them by hand.  I’m not sure what happens if the pinion gear comes off while riding; but you do have the bent tab nut retention there.

It says to replace the nuts on the rear sprocket  but I will just use medium thread lock I think.

IIRC the rear axle nut is 100nm as well..!

 I used Honda's M77 grease at £18 for 75g instead of BMW £28 for 30g.

Hi

I bought a Talon 43T sprocket for the rear of my s1000xr...anyway what I want to know is do I still need to use a 525 chain or do you recommend something else?...I also imagine the chain will need to be shortened....what do you recommend for the best chain to buy....and I guess new nuts and lock washers are needed as well?..should I buy these separate or will dealer have these in stock?...cannot remember what size is needed but will research....and one othere question..how much is a large 13 oz can of PLEXXUS in the UK?

thanks

TJ
