Is any up and down play in the swing arm due to possible wear in the linkage

needle rollers acceptable.

A strange question maybe, but the play is very slight and Im not sure

new bearings are such close tolerance to eliminate all the play.

Anyone with experience? Ive stripped/ cleaned and regreased the bearings

every couple of years with no problems so far. Bike's done about 20k miles.

The front bolt on the dog bone where it mounts to the frame is a slightly smaller diameter to the dog bone pin bore so if you pull up on the swingarm you can sometimes feel a little play. That might be what you’re feeling but I doubt a tiny bit of movement generally is unusual once the bearings/pins have seen a few miles.

Decided to strip, check, re grease the linkage as its getting on for its 2 year check anyway.

All bearings and pins ok and last re grease still looking like new.

As you say Spoonz, all the play is due to the difference between the inner diameter of the pins and the mounting bolt diameters, especially that front one.

I've got plastic washers fitted to both dog bone pins but found the right inner linkage triangle wearing against the swing arm mount. The space wont take one of the plastic washers but I shaved off some thickness from a fibre washer and put that in.

You’ve always got a little play, all the bearings and linkages have a small amount of play and it adds up, up and down is fine but you don’t want any side to side.
