Rear Sprocket Assembly has play (axially)

[mnikodemus]

Hi Everybody,

When checking my chain and sprockets the other day, I found out that the rear sprocket has play (side-to-side / axially). I will describe it referring to this diagram:
http://www.bikebandit.com/oem-parts/2004-suzuki-sv650-sv650k4/o/m147649#sch505600

The rear sprocket (19) moves together with the drum (14) relative to the wheel hub. There is about 3 mm of play. I have taken everything apart and checked every part and made sure everything was in its proper place as in the diagram. I noticed the hub spacer (2) sits loosely (lots of play) inside the hub between the two bearings, but I think that is intentional so that there is only load on the bearing during operation.

The curshions / shock absorbers that sit inside the wheel hub (18.) look worn, they formed themselves to the shape of the drum (14). I tried rotating the drum in different configurations relative to the hub to see if maybe it would seat better, but it made no difference.

Should I just replace these shock absorbers? Is this a regular wear part? Has anybody come across this? I torqued the axle nut to spec, 73 ft-lbs.

Thanks for any help!

No other modifications as far as I can tell (bought it used)
I think chain and sprockets are still stock. 44T in the rear. I'll replace these but want to get this sorted out first.

As far as I know cush drive rubbers are worn out when the sprocket and carrier can move/twist forwards and backwards with out the wheel moving, I am not sure if they would let the carrier move in/out, but they get a hard life and do wear.

sounds like the sprocket carrier bearing is fubar

Hmmmm I did not notice any play in the rotational direction.

Bibio, is that the bearing labeled 16 in the diagram? Have you had this problem before?

Thanks for your help.

no but its the only one that could cause the play you are on about. easy test, take the sprocket carrier off and feel the bearing for play. the inner race should be smooth rotating without play or grinding/notchyness. if any play is felt then the bearing is fubar. while your at it you might as well test the wheel bearings as well.

Bibio, thanks so much for your expertise. I changed the sprocket carrier bearing and look there, no more play! :p

While I was at it, I also attempted to change the wheel bearings but ran into some difficulties [new thread]. Would be great if you could take a look at it.

Cheers
