7x12 Horizontal Bandsaw Drive Wheel Replacement

This saw is around 17 years old and gets used daily for cutting metal and plastic stock to make parts for the business. One day, the cast iron drive wheel let go with a loud bang, nearly cracking in 2 pieces.

In this video, we'll be replacing the drive wheel. End result was the unexpected elimination of most of the vibration the saw had been having. Could be the initiation of the crack in the drive wheel started that vibration a few years back.

Closer examination showed it was likely a bad casting with lots of porosity visible in the 25mm center bore. Might have been able to weld this up with some aluminum bronze filler, but it would have broken in short order.

Harbor Freight had no parts available for this model saw that was discontinued so 10-15 years ago. Their new model saw is nearly identical, having a few new guards, safety features and paint scheme. However, they have no cross references for parts. Browsing their on-line parts page for this saw, shows nothing like this sort of part.

Luckily Grizzly has an identical saw and their updated parts ordering page is excellent.
