Isuzu 4BD1 4BG1 Crankshaft Pulley 8-97138018-0 for Excavator & Truck Engine

Product Details

Product Overview

This premium Crankshaft Pulley, identified by the critical OEM part number 8-97138018-0 (also referenced as 8971380180), is a genuine replacement component specifically designed for the Isuzu 4BD1 and 4BG1 diesel engine series. As a primary drive component, this pulley is essential for transferring rotational force from the crankshaft to drive the alternator, water pump, power steering pump, and air conditioning compressor via the serpentine or V-belt system.

Engineered for heavy-duty applications, this crankshaft pulley is commonly used in a wide range of industrial machinery, including excavators and trucks manufactured between 1980 and 2006. It is a direct fit for Isuzu engine models that require robust, long-lasting parts to withstand the high torque and continuous operation demands of construction and commercial transport environments. This genuine component ensures precise balance and alignment, which is critical for minimizing vibration and preventing premature wear on the crankshaft and front engine seals.

FAQ

Q: Will this 8-97138018-0 crankshaft pulley fit my Isuzu 4BD1 engine in a Hitachi excavator?
A: This pulley is specifically designed for the Isuzu 4BD1 and 4BG1 engine families. It is commonly used in excavators and trucks. However, to confirm exact fitment, we recommend checking your original pulley’s part number (e.g., 8-97138018-0 or 8971380180) and comparing the bolt pattern, diameter, and thickness. The year range for this application is 1980-2006.

Q: What are the signs of a failing crankshaft pulley, and how do I install the new one?
A: Common signs include visible wobbling, a chirping or squealing noise from the belt area, increased engine vibration, or a misaligned serpentine belt. Installation requires a mechanic to remove the drive belt(s), use a special puller to remove the old pulley (avoiding damage to the crankshaft nose), and torque the new pulley’s center bolt to the manufacturer’s specification. We recommend consulting a service manual for your specific engine model.

Q: Is this a genuine Isuzu part, and what is the warranty?
A: Yes, this part is listed as a genuine condition item, originating from Japan. It is backed by a 3-month warranty against manufacturing defects. Should you encounter any issues after the warranty period, we offer video technical support to help diagnose and resolve the problem.
