Failure Symptoms

The first sign of a failing starter is often slow cranking or intermittent engagement. If ignored, the starter may eventually fail to crank the engine altogether, leaving the equipment inoperable. Continued attempts to start with a failing starter can drain the battery and potentially damage the flywheel ring gear.

Installation Tip

Before installation, ensure the new starter's mounting surfaces are clean and free of debris. Avoid overtightening the mounting bolts, as this can strip the threads or damage the starter housing.

Service Note

Inspect the battery terminals and cables for corrosion and ensure they are securely fastened.
