250-500cc Sloppy Swing arm

Pulled my '10 3hunge onto it's stand so I could oil the chain and i noticed when back wheel left the ground there was a small 5mm slop in the rocker lever ( bottom mount of the shock)..
Is there meant to any or am I up for overhaul of back end?

There is a little slack in the linkage system. If there is excessive then your bearings need some love. Sounds like yours may need love. When was the last time they were serviced?

I grease them pretty regulary, but never been apart..

Swing arm and lower shock bearings should press straight out. The rest in the linkage require and internal bearing puller or die grinder to get one side out before you can press the other side out as they are seated to a shoulder.

Well, if you pull it apart and they look good, then you know that's the normal amount of slack.

looks like I'll be pullin it apart... I'v replaced the whole kit and kaboodle on my old te410 and remember how much fun that was...not

You said there was 5mm of slop; is that measured at the rear wheel or at the linkage?

That would be a LOT of slop at the linkage. If you really have that much, one or more bearings are probably shot.

There's a fait bit of movement at the back wheel, at the linkage theres a small amount. havn't had a chance to get apart yet but will start undressing her tomorow.. time for a tidy up. lookin at fork oil replacement and new skf ultra low friction seals, fresh piston n rings(100hrs on her) and rear end( hope she may just need a regrease... maybe hitting the logs a bit hard, need to learn the unweighting technique..
