FAQ

1. Is this cylinder head gasket compatible with my Komatsu 4D94 engine?

Yes, this part (8-98023-526-0) is the OEM-spec gasket for the Komatsu 4D94 engine. However, we recommend checking your engine serial number and comparing it to the OEM part number on your old gasket for absolute confirmation. Variations may exist in later model years.

2. What tools are required for installation?

Installation requires standard engine repair tools, including a torque wrench, socket set, and a gasket scraper. It is critical to follow the manufacturer’s torque sequence and specifications (typically 30-40 Nm for initial pass, then 90-degree angle tightening). Always clean the mating surfaces thoroughly before fitting.

3. Does this gasket come with a warranty, and what is its expected lifespan?

We offer a 12-month warranty against manufacturing defects. Under normal operating conditions and proper installation, this gasket can last the life of the engine (50,000+ hours) before requiring replacement. Regular maintenance, such as checking coolant and oil levels, will extend its service life.
