Vandercook SP15, lowering gear side of rear form roller

The gear side of the rear roller on our SP15 will not lower enough to hit a roller-setting gauge. It does have a range of motion, just will not descend low enough to contact the gauge on the gear side. The roller measures about 1/8″ less than 2 1/2″ in diameter. The tip diameter of the gear is just under 2 5/8″. Would you advise re-casting the rollers in this case? Or is it possible the gear is slightly too large?

Our SP15 had the same issue even after installing new rollers. When Dave Seat of Hot Metal Services was here a few years ago to do some preventive maintenance he noticed that there previously had been a nylon shim strip placed under the gear track.
Removing that thin strip lowered the roller enough and has not affected any operation of the press.

I had an SP-15 with the same problem. I replaced the 40-tooth gear with a 38-tooth gear which perfectly matched the 1/8″ undersize of the roller.

I had to do some machining to fit the gear, but it was (my time)+(cost of gear) vs (cost of new rollers) and the former won out.

Hey Nick, are you still at OCADU?

Get new rollers. You’ll be happy you did.
