About six years ago, I replaced the 1/2” V belt on my jointer with a link belt. I bought a 1/2” link belt, but found that there was not enough clearance around the upper pulley. I used that belt on my drill press instead and bought a 3/8” link belt for the jointer. It has been working great ever since.

Today I picked up an older lathe. I plan to replace the 1/2” V-belt with a link belt here too. I tested with a piece of 1/2” link belt and again there is not enough clearance between the upper pulley and the guard. The link belt does not sit as deep in the pulley as the original belt.

Maybe I just ran into two cases where the pulley geometry does not match that of the link belt. The jointer is a Delta from 1999 and the lathe is a Rockwell from 1974.

Has anyone else noticed this?

the link belts are flat belts and not v-belts, hence they do not fit “into” the pulleys as the original belts. just the nature of the beast. as long as there is enough tension on there it should work just fine though. you can always get ‘gates’ brand belt which is a v-belt and is a high quality belt (and does not develop memory bumps) for a 1/3 of the cost of a link-belt

Sharon,

The ones that I got from Fenner are V-belts. They do have a V profile, but it seems that the angle is different, which causes the difference in where they ride on the pulley.
