Crankshaft Pulley HD-2094 PC300-7 Suitable for Komatsu Engine Parts

Product Details

Product Overview

This Crankshaft Pulley, identified by part number HD-2094, is a precision-engineered component designed for the Komatsu PC300-7 excavator. As a critical part of the engine’s front accessory drive, this pulley ensures the proper tension and rotation of the serpentine belt, which drives the alternator, water pump, and other ancillary systems.

Manufactured to meet OEM size and performance specifications, this pulley is suitable for Komatsu engines commonly found in heavy construction equipment. The HD-2094 is a direct replacement part that helps maintain the engine’s operational efficiency and reliability, reducing the risk of belt slippage, vibration, and premature wear on other drive components.

This component is commonly used in the SAA6D125E engine family, which powers the PC300-7 model. It is a robust, diesel-specific part built to withstand the high torque and demanding conditions of industrial and construction environments.

FAQ

Q: Is this crankshaft pulley a direct fit for my Komatsu PC300-7 excavator?
Yes, the HD-2094 pulley is designed as a direct replacement for the Komatsu PC300-7 model. It matches the OEM dimensions and bolt pattern. However, we always recommend verifying your existing part number (e.g., 6127-31-1100) against the HD-2094 to ensure 100% compatibility with your specific engine variant.

Q: What are the signs that my crankshaft pulley needs to be replaced?
Common failure indicators include visible cracks or separation in the rubber dampener, wobbling or excessive vibration of the pulley, a squealing belt noise, or the serpentine belt coming off track. If you notice any of these symptoms, inspect the pulley immediately, as a failure can lead to belt breakage and loss of engine cooling or charging.

Q: How should I install this part and what maintenance is required?
Installation requires standard mechanical tools and should be performed on a cool engine. You will need to remove the serpentine belt and the center retaining bolt. It is critical to torque the center bolt to the manufacturer’s specification (refer to your service manual). This is a non-serviceable component; no periodic maintenance is required other than visual inspection during routine belt checks. Always replace the retaining bolt if it is a torque-to-yield type.
