FAQ

Q1: How can I confirm this starter motor fits my machine?
A: Please verify your original part number against the list provided. The most critical match is the OEM number (02T911023) and the physical configuration (12-tooth pinion, 24V). Cross-check the mounting flange pattern and the distance between mounting holes on your old starter.

Q2: What is the installation procedure for this starter?
A: Standard installation. Always disconnect the battery negative terminal first. Clean the mounting surface on the flywheel housing. Apply a small amount of anti-seize compound to the mounting bolts (torque to manufacturer specs, typically 40-50 Nm). Ensure all electrical connections (B+, S terminal, and ground) are clean and tight.

Q3: What maintenance does this starter motor require?
A: This is a sealed, maintenance-free unit under normal operating conditions. Regularly inspect the electrical connections for corrosion and ensure the battery is in good health, as a weak battery can overwork the starter. For extreme dusty environments, periodic cleaning of the drive end housing is recommended to prevent gear binding.
