Question - Free play in swing arm pivot - SV650.org

12-02-07, 08:42 AM

How much free play is acceptable in the swinging arm bearings?

With the wheel out and shock and cushion lever removed I have slight movement between the right hand pivot spacer (item 7 on the exploded diagram of the assembly) and the swing arm (10) which translates to about 2 to 3 mm side to side movement at the wheel end of the swing arm.

If the swing arm pivot shaft was not tightened to the correct torque (15 Nm) could this result in free play? i.e. is it worth undoing the lock nuts and checking the torque setting on the pivot shaft?

And finally, if the swing arm pivot bearings are shot, how much am I looking at to have them replaced?

The bike is a K3 pointy with 18k.

That sounds like a lot to me - is it rocking on the pivot shaft or simply sliding from side to side?

I think it's rocking.

Yep, that really doesn't sound right to me...

They are f*cked then, unusual for swing arm bearings to go on a road bike.....

It may be worth tightening it up to the correct torque (We may be at cross purposes here but IIRC on the ZX6 the swing arm nut is tightened to something like 110Nm).

When lifting and lowing the swing arm it should move smoothly without notchiness or feeling like it's being urned through cement / gravel. There should be no lateral movement.

Agreed. mines at 50k with no play

Try an NC30 arm...i think. Still lots of work
