Useful Information

Description and Purpose:

This New Genuine Starter Motor 39MT with Part Number: 21019456 is engineered to deliver reliable cranking power for heavy-duty applications. Brand: Volvo/Mack. With a 12V system, SAE 3 mounting, 12 pinion teeth, and 8/10 pitch, it ensures strong and consistent starts even under demanding conditions. The clockwise rotation and insulated polarity provide compatibility across a wide range of heavy-duty equipment.

Why Replacement is Important:

A failing starter can lead to slow or incomplete engine starts, leaving vehicles immobile and delaying operations. Installing this genuine Volvo/Mack 39MT restores reliable ignition performance, reducing downtime and preventing further strain on the electrical system.

Impact on Vehicle Performance:

Using a fully functional starter guarantees smooth, dependable engine starts, protects the battery and electrical components, and maintains overall vehicle reliability. This is critical for trucks that face frequent stops, heavy loads, and harsh operating environments.
