For the Prep/Master Jr

This kit is matched to the Prep/Master® Jr — note it uses the 502 Morflex coupler (the Jr and Sr take the 502; the larger Prep/Masters use the 602). Everything in the kit is sized for the Jr.

Why Keep One on Hand?

Couplers and gearbox hardware are wear parts — when they go, your grinder won’t drive right. Having the kit on the shelf means you can service your Jr on schedule and get back to work fast instead of waiting on parts.
