Thread: Wheel Alignment problems - HELP + rubber tyres Vs cork?

I have recently purchased a used SOCOMEC 460 bandsaw. The machine is in excellent condition and appears to have had only light use. I have purchased it to upgrade from a standard 14" model due to the amount of resawing I perform. I recognise the SOCOMEC is still far from the perfect resaw machine in this size but it is about as big as I can fit in my workshop. My question related to the alignment between the upper and lower wheels. Iam certain they are around 1/4" or 6mm out of alignment (lower wheel further back). It is almost impossible to verify as the welded frame makes it impossible to lay a straightedge across both wheels. Despite owning a few bandsaws and having tuned them all for resawing I have never had to adjust the wheels into alignment. Hence my question: can anyone guide me in this process? I have attached a couple of photos of the bottom wheel both front and rear to understand how the shaft and bearings are aligned. The 4 bolts at the rear appear to be arranged to keep a bushing centred and I presume the bolt from the front side can be loosened to move the shaft in and out but I'm not sure. There is no guidance in the manual. Any help would be appreciated.

Also, this bandsaw has cork lined wheels as opposed to the usual rubber tyres I have used before. There is some wear on the cork but can anyone provide guidance on the benefits of cork Vs rubber and vice versa. If I need to have the wheels upgraded with rubber tyres is there anyone in the Brisbane area that can be recommended?

Many thanks
