Product Introduction

• Structure: A high-torque, reduction-gear starter with a cast-aluminum housing, a series-wound DC motor, and an integrated solenoid. It features a pinion gear that engages with the engine flywheel ring gear, and a heat-resistant electrical connector for reliable power delivery.

• Performance: Delivers high cranking torque to turn over large-displacement diesel engines, even at low temperatures. The reduction-gear design increases torque output while reducing electrical current draw, protecting the vehicle’s battery and charging system.

Core Function

1. Engine Cranking: Converts electrical energy from the battery into mechanical torque to rotate the engine crankshaft, initiating the combustion cycle.

2. Pinion Engagement: The integrated solenoid pushes the pinion gear into engagement with the flywheel ring gear and activates the motor simultaneously.

Frequently Asked Questions – Starter Motor 612600091077 WEICHAI

Is Starter Motor 612600091077 a direct OEM replacement?

Yes. This starter motor matches the original WEICHAI specification for part number 612600091077, including bolt pattern, electrical connections, pinion tooth count, and torque output. It installs without modification on all listed engine platforms.

What is the expected service life of this starter motor?

Under normal operating conditions, this unit delivers approximately 80,000 to 100,000 start cycles. For a typical long-haul truck averaging 4–6 daily starts, that translates to roughly 4–5 years of service before rebuild or replacement becomes necessary.

Can this starter motor handle extreme cold weather starts?

Absolutely. The motor is rated for operation down to -40°C. Its high locked-torque output (≥55 N·m) ensures sufficient cranking speed to achieve compression ignition even when engine oil viscosity increases dramatically in arctic conditions.

How does the 12-tooth pinion gear engagement work?

This starter uses an electromagnetic pre-engaged design. When the ignition key activates the solenoid, the pinion gear extends into the flywheel ring gear before the main motor circuit energizes. This sequence reduces gear clash, minimizes tooth wear, and extends both starter and flywheel service life.

What quality testing does each unit undergo before shipping?

Every Starter Motor 612600091077 passes a 5-point inspection: no-load speed verification (≥1,000 RPM), no-load current draw (≤110A), locked-torque bench test (≥55 N·m), insulation resistance measurement (≥1 MΩ at 500V DC), and solenoid engagement cycle testing (minimum 50 rapid cycles without failure).

Is this starter motor compatible with WP12 engines or only WP10?

This unit fits both WEICHAI WP10 and WP12 engine families, as well as the older WD615 and WD618 platforms. The 3-bolt flange mounting geometry and flywheel ring gear specifications are shared across these engine series.
