BOSCH 0986020170 Starter Motor

The BOSCH 0986020170 Starter Motor is a high‑performance ignition component engineered to deliver reliable engine start-up under a wide range of operating conditions. Designed for heavy‑duty commercial vehicles, this starter motor combines robust construction with advanced electrical characteristics to ensure consistent performance over the vehicle’s service life.

Key Technical Specifications

• Voltage: 24 V DC – compatible with standard commercial vehicle battery systems.
• Current Rating: 4 kW – sufficient to crank engines ranging from 6.7 L six‑cylinder to 3.9 L four‑cylinder configurations.
• Dimensions: Approximate length of 320 mm, width and height tailored for tight engine bay spaces.
• Weight: Lightweight alloy construction reduces overall vehicle mass, improving fuel efficiency.
• Mounting Type: Universal mounting bracket system compatible with IVECO, HEULIEZ, IRISBUS, TEMSA, and Nissan CASE IH platforms.

Design Features & Engineering Excellence

The starter motor incorporates a high‑strength steel armature surrounded by a precisely wound copper windings assembly. This configuration ensures optimal magnetic flux distribution, resulting in efficient torque generation during cranking. The housing is fabricated from heat‑treated aluminum alloy, providing excellent thermal conductivity while maintaining structural integrity.

A key innovation in the 0986020170 model is its integrated temperature sensor. This sensor continuously monitors internal temperatures, allowing the vehicle’s control unit to modulate current draw and prevent overheating. The result is a starter that remains reliable even during repeated start‑stop cycles common in urban freight operations.

Compatibility & Application Range

The BOSCH 0986020170 Starter Motor is engineered to fit a broad spectrum of commercial vehicle engines. Its universal mounting design and standardized electrical interface make it suitable for:

• IVECO EuroCargo I‑III series – including the Tector BUS and Crossway models.
• HEULIEZ Gx 137, IRISBUS ACCESS, Citelis, and TEMSA Crossway platforms.
• Nissan CASE IH Cummins engines ranging from 6.7 L six‑cylinders to 3.9 L four‑cylinders.
• Other OEM configurations that require a 24 V, 4 kW starter motor with a length of approximately 320 mm.

Installation Guidelines

1. Preparation: Disconnect the battery and ensure all electrical connections are insulated. Verify that the engine bay is clear of obstructions.
2. Mounting: Align the starter motor with the mounting bracket on the engine block. Secure using the supplied bolts, tightening to the manufacturer’s torque specifications.
3. Electrical Connection: Connect the high‑current terminal to the battery positive cable and the low‑voltage terminal to the ignition switch or ECU output. Use insulated connectors rated for at least 4 kW.
4. Testing: Reconnect the battery and perform a cranking test. Observe the starter’s operation; it should engage smoothly without excessive noise or vibration.

Maintenance & Longevity Tips

Although the BOSCH 0986020170 Starter Motor is designed for durability, routine checks can extend its service life:

• Inspect electrical connections every 12 months for corrosion or looseness.
• Verify that the mounting bolts remain tight; re‑torque if necessary.
• Check the temperature sensor output via a diagnostic scan tool to ensure it remains within operating limits.
• Avoid exposing the starter to excessive moisture; use protective coatings if operating in harsh environments.

Performance Highlights

The combination of high‑current capability, efficient magnetic design, and thermal management results in a starter motor that:

• Provides rapid engine cranking even at low ambient temperatures.
• Maintains consistent torque output across a wide range of engine speeds.
• Reduces electrical load on the battery during start‑up, preserving reserve capacity for auxiliary systems.
• Operates quietly, minimizing noise pollution in urban delivery settings.

Conclusion

The BOSCH 0986020170 Starter Motor exemplifies the brand’s commitment to reliability and engineering precision. Its universal fitment, robust construction, and advanced thermal management make it an ideal choice for fleet operators seeking a dependable starting solution across diverse commercial vehicle platforms.
