• Functions

1.Maintenance-Free Operation: The sealed ball bearing and corrosion-resistant materials (cast aluminum, zinc-plated hardware) eliminate the need for lubrication or regular servicing.

2.Durability for Harsh Environments: Withstands vibration, extreme temperatures, and exposure to engine oils/coolants—critical for heavy-duty applications like long-haul trucking or construction.

3.Engine-Specific Fit: Engineered to match the exact bolt patterns, belt paths, and tension requirements of target Cummins engines (ISX15/QSX15 for 3936213; ISB6.7/QSB6.7 for 3937556), ensuring no modification is needed during installation.
