Product Details
Product Overview
This high-quality 6D105 Crankshaft Pulley is a direct replacement component designed for use with Komatsu 6D105 series diesel engines. As a critical part of the engine’s front-end accessory drive (FEAD) system, this pulley ensures proper belt alignment and tension for the alternator, water pump, and fan systems.
Manufactured to OEM specifications, this crankshaft pulley is commonly used in heavy construction equipment such as excavators, bulldozers, and loaders, as well as industrial vehicles like forklifts and buses. The part is engineered to withstand the high torsional loads and vibration inherent in diesel engine operation, providing reliable performance in demanding work environments.
Key Features & Benefits
Precision OEM Fitment – Manufactured to match original Komatsu 6D105 specifications for straightforward bolt-on installation without modification.
Durable Construction – Made from high-strength cast iron or steel to resist wear, cracking, and fatigue under continuous heavy-load operation.
Vibration Dampening – Designed to reduce engine vibration transfer to the belt system, protecting alternator and water pump bearings.
Corrosion Resistant Finish – Coated or painted to prevent rust and degradation in harsh outdoor and engine bay environments.
Rigorous Quality Control – Each unit undergoes dimensional inspection and surface finish testing to ensure concentricity and balance.
Cost-Effective Replacement – Offers a reliable alternative to genuine OEM parts at a competitive price point for fleet maintenance.

FAQ
Q: How can I confirm this 6D105 crankshaft pulley fits my Komatsu engine?
A: Please verify your engine’s serial number and the original part number on the existing pulley. The 6D105 series has multiple variants (e.g., 6D105-1, 6D105-2). Measure the pulley diameter, number of grooves, and bolt pattern to confirm compatibility. If in doubt, contact our technical support with your engine details.
Q: What are the signs of a failing crankshaft pulley on a 6D105 engine?
A: Common symptoms include: visible wobbling or misalignment of the pulley, unusual vibration at idle, squealing or chirping noises from the belt area, alternator not charging properly, or coolant overheating due to water pump under-drive. Inspect the rubber dampener (if present) for cracks or separation. Replace immediately if any damage is found to prevent belt failure or engine damage.
Q: Can this pulley be installed without special tools?
A: Installation typically requires standard hand tools including a socket set and torque wrench. However, accessing the crankshaft pulley may require removing the radiator fan and shroud on some equipment. Always consult the Komatsu service manual for torque specifications (typically 200-280 Nm for the crankshaft bolt) and proper alignment procedures. We recommend professional installation by a qualified diesel mechanic.
