Thankyou gents,
Deejay - it's no problem on a 17" like yours, I'm just buggered by this 3 piece roller.
Bruce - The whole thing is out of the machine - I've got the the sprocket and drive side roller off, but I'm snookered by the small 3" roller in the middle. I've either got to get that off or pull off the bearing and bearing housing off the other end.
