FAQ

Q: How do I verify that this cylinder head bolt fits my Komatsu PC300-8 excavator?
A: Check your engine model plate to confirm it is a 6D114 series engine. Measure the bolt length and thread diameter against your original bolt. The OEM part number 8-98023-526-0 should match your existing bolt. For absolute certainty, remove one bolt and compare dimensions before ordering multiple units.

Q: What is the recommended torque specification for installing this cylinder head bolt?
A: For the 6D114 engine, typical installation follows a multi-step torque sequence: first tighten all bolts to 80 Nm in sequence, then to 160 Nm, followed by an additional 90-degree turn angle. Always refer to the Komatsu service manual for your specific engine serial number, as torque values may vary slightly between engine variants.

Q: Can I reuse these cylinder head bolts after removal?
A: Cylinder head bolts are typically torque-to-yield (TTY) fasteners that stretch during initial installation. We strongly recommend replacing all cylinder head bolts with new ones whenever the cylinder head is removed. Reusing old bolts can result in improper clamping force, leading to head gasket failure or engine damage. Always install new bolts for reliable performance.
