I've used it on Elm cross sections , didn't really get into it too much some people preferred splits in the wood .I have got a book somewhere, doesn't come liquid, a bit like wax.

saws uk website may still have the dimnsions

can't see how it can work without rubber tires . must be allsorts of wear metal to meal I I guess the blade teeth plus 1 -2 mm behind gullet should protrude in front of the band wheel once you start cutting this will force the blade slightly back if you do not have rubber bands then the down set teeth will be wearing on the alloy band wheel ,so if this is wearing out then as some one said the bad wheel will want to go to the highest point which is further back ,but can't because those bearing you showed are backing bearings to stop the blade going back ,not guide bearings. blades coming off can cause a lot of damage
