Shaper with powerfeed kickback

[Rod Sheridan]

I have never seen a sprocket failure on a power feeder.

I have seen gear failures internally.

That roller is really dried out, no wonder you had an issue with it.

You'll really like your new polyurethane rollers..............Regards, Rod.

Are the tires providing inconsistent pressure as they turn? Some things that could cause it;

1. Bad bearings.

2. Bent shaft

3. Out of round tires

4. Tires softer on one side

You should be able to set up a dial indicator against the tires and run them. Check high, low and center.

To check for softness tap with a small ball peen hammer.
