Removing front Sprocket

[bullockbeamer]

I have just ordered a new DID chain and sprockets for my F800 GS. Does anyone know how I can remove the front sprocket, as up to now I have always got the dealer to do this? Do I need to get a special tool?

I have the tool for removing and replacing the chain, which is straight forward.

Thanks

Front Sprocket Removal

I used a 3 leg puller and a little bit of heat to remove mine.

Don't heat the spline .......... unless you want to ruin the oil seal of course!

Mine just floated off when changing down a tooth.
Leaving the back wheel in place meant that first gear could be used to hold back, when assistant just had to hold on to the bike when 600mm breaker bar was applied to the retaining bolt.

Mine too. There are no special tools needed. You will need to loosen the axel and bump the wheel forward to get slack. Then just unbolt and remove the cover, sprocket, clean and lube splines and install the new sprocket.

30mm socket, breaker bar with 6ft long 1-1/2" pipe and a friend.

Don't forget to bend the tab washer back and tighten back to the correct torque.

Feck me, how tight is this meant to be?

 

[Clifton]

I believe they call for blue Locktite and torque to 50NM (37 ft lb). It's only a M10 x 1.5 fastener. BTW the front sprocket has an offset be sure to put it on the same direction as the stock one was.

WTF do you list mechanical sympathy as one of your strong points

Having actually done this only last night, I speak with the advantage of experience.

The torque required to tighten the nut I have been told is 200 nm, however, I would like to see some proof

The Correct torque would be 50 Nm, and its a 'dished' spring washer, no locking tab.

i would have thought around 50nm would be more like it .

 

[ymfb]

Just found it should be 140 nM plus loctite 243

still sounds like overkill to me

Where are you getting this info? Thats way tight for a 10mm screw! Haynes manual says 50Nm and LT243
