FAQ

Q: How do I confirm this gasket kit fits my Komatsu PC20R-8 excavator?

A: First, verify your engine model number. The Komatsu PC20R-8 typically uses the 3D85 engine, which is the same block as the Yanmar 3TN85. Check the engine nameplate for the model number (3D85 or 3TN85). If your engine matches, this kit is designed for it. If you have a different engine variant, please provide your engine serial number to our support team for cross-reference.

Q: Does this kit include the head gasket and valve stem seals?

A: Yes, this is a full gasket kit intended for a complete engine overhaul. It includes the cylinder head gasket, valve stem seals, oil pan gasket, intake/exhaust manifold gaskets, and all necessary O-rings and seals for the oil cooler cover and other engine components. It is designed to cover all sealing points in a 3D85/3TN85 engine rebuild.

Q: What is the recommended storage and shelf life for this gasket kit?

A: Gaskets and seals should be stored in a cool, dry place away from direct sunlight and extreme temperatures. The ideal storage temperature is between 15°C and 25°C (59°F to 77°F). Under proper storage conditions, these rubber and composite components have a shelf life of up to 5 years from the date of manufacture. Avoid exposing the kit to ozone or chemicals that could degrade the rubber seals.
