Single Sided Swingarm - Eccentric Cam

[Alex A]

I'm attempting to adjust the chain on a friends Triumph T595. Undone the locking bolt and have the tool to turn the cam.

Unfortunately I don't have a suitable paddock stand so it's difficult to turn against the weight of the bike, but has just required a bit of muscle in the past. The chain's now a bit loose but the cam doesn't want to turn any further at all.

Are there any markers to check whether it's it's at the extent of it's travel?

If it won't turn clockwise turn it anti-clockwise a bit then clockwise again until you feel if it hits a stop or not.

Didnt think there was a stop to them, should go right round. I know my VFR400 one does.

If it's anything like the VFR750 one (and I think it is very similar). The cam will turn all the way round. People use it to raise/lower the ride height slightly depending on if the spindle is above of below the midline.

As such, you could try turning it all the way round the other way, it'll loosen then start to tighten again.

They do get gummed up with crap off the road, which on the VFR one goes up through a hole near the front of the swingarm, runs along it and gets deposited right in the middle of the hub assembly where there is a groove you could swear had been put there just to accumulate dust and small stones.

When I stripped mine for new bearings, I cleaned all the crud out, greased the outside of the hub assembly then filled the void in the swingarm with expanding foam to stop it happening again.

Thanks all.

All the way around makes sense.

I think it's just badly gummed up (doesn't seem to want to shift either way, having tried it). Hasn't been degreased for some time (i.e. years) by the looks of it. And with a tool that's a little bent (i.e. straightened) I'm not getting a good purchase on the teeth of the cam. Would probably be doable relatively easily with a single sided paddock stand.

A good squirt of penetrating oil followed by working it back and forth ought to work wonders.
