Nautilus CC Tread keeps falling off

[TheMerk]

I replaced the treads last fall thinking that would solve the issue, but the tread on one side keeps falling off. Not every cleaning cycle, but certainly 1 out of every 5 on average.

Is there any adjustment time be made to the rollers to make the tread “pulley” more tight?

Here is a bump to get this in front of more eyes.

I think the rear pulley wheel has more play than it should. It definitely has more play than the wheel on the opposite side, letting the track roll off sometimes.

I can’t tell how to take the wheel off. Does anyone know how to do that?
