Thanks Grumpy,

The Roller is only dented inwards in 3 small spots, the biggest being the size of a 10c piece. It doesn't seem deformed outwards which is a good thing and seems to roll ok..

As for the engine no. I can make out the following:
Model: 80202 Type: 1735-01 Code: 82111901

At closer inspection it looks like the cutting edge is wearing in 2 spots, one side by about 1mm and the other side by about .5mm

When turning the cylinder two out of the 6 blades touch the cutting edge where it is wearing. The wearing points on the cutting edge are at opposite ends. Seems to be indicating an uneven machined cylinder by a few thou. Will the cylinder require a clean up? Also it does not cut paper as suggested, but i don't want to lower the adjustment anymore due to making a mess of the cutting edge (hope thats the right terminology..)

To remove the cylinder for clean up if neccessary, i see two end caps that have to be removed. How does the cylinder then be removed from the drive sprocket and lifted out of the machine?

Hope my explanations are not to confusing..

Cheers, Craig.
