Sprockets

[Wilee7]

How do i remove the front sprocket on my bike i have a 1982 GS550L

Welcome. Remove the shift linkage and sprocket cover. Keep the chain on or put it back on (at least drape it over the tops of the sprockets without slack). Flatten the lock washer under the front sprocket nut and hold the rear brake. It's torqued down to about 45 ft-lbs, 32mm socket.

I just did this last weekend and took pictures. Could post them if interested.

I recommend an air wrench, it moves fast. Chck the alignment before and after you are done, there may be shims installed behind to align with the rear sprocket.

Here you go.

Bike in neutral, up on center stand.

Remove the two bolts holding on the front peg. Remove the shift linkage pinch bolt and snap ring (don't lose the washer behind it).



The linkage pulls straight off. Now remove the six bolts (6mm socket) holding on the sprocket cover. Watch they are three different sizes during re-assembly. This is an 82 550L like yours, the clutch cable will still be attached but you can leave it there. I just bungee'd the cover out of the way. Having a couple of cans of brake-kleen read is nice, 'cos it's going to be dirty back there.



Flatten the lock washer holding the sprocket nut using a screwdriver and mallet or similar.



Use the rear brake (chain must still be on!) to hold the sprocket steady and loosen the nut with a 32mm socket. That torques on at about 45 lb-ft IIRC. An assistant helps, or stand on the brake and bend over the bike.



Installation is reverse of removal (call me Mr. Chilton).

Is your chain stretched? Are you just replacing the front sprocket and not the chain/rear sprocket? The front sprocket is the easy part of that whole job. But a new sprocket with an old chain will accelerate wear of both.

A 2x2 through the rear wheel against the swing arm is another way to hold the wheel if you don't have anyone to step on the brake pedal for you.

I had my daughter step on the rear brake while I used a breaker bar with a socket on mine.
