Auto Specialties recommends that these pulleys be installed by a qualified mechanic.

1. Remove existing belt and craftshaft pulley

2. Install new pulley with internal hex bolts supplied. Tighten hex bolts evenly. Use Loclite #242 (or equivalent) on threads.

3. If ASP Bracket (020400)is not used, install new belt. Belts are readily available at most parts stores.
