💡 How do you select a proper double groove v belt sheave to stay handy on the truck bed and save cash on downtime?
Match the exact groove geometry and bore diameter to your original factory specifications.
- Thread the locking bolts into dry moly spray to prevent galling threads when removing stubborn hardware
- Square the mounting face against the engine frame so the drive belt tracks dead center under peak RPM
- Swap faded pulleys with fresh cast iron units when you spot heat cracks or uneven wear on the rim
