FAQ

Q1: Is this cylinder head bolt a direct replacement for the original Komatsu part?
A: Yes, this bolt is manufactured to OEM specifications for the Komatsu 6D114 engine in PC300-8 machines. It matches the dimensions, thread pitch, and hardness requirements of the original part (OEM 8-98023-526-0). However, we recommend comparing your existing part to ensure compatibility with your specific engine variant.

Q2: What is the recommended torque specification for installation?
A: For the 6D114 cylinder head bolts, follow Komatsu’s official torque procedure which typically involves a multi-step process. Always refer to your engine service manual for exact torque values and tightening sequence. As a general guideline, these bolts require precise torque application in stages, often followed by an angle-tightening step. Incorrect torque can lead to head gasket failure or engine damage.

Q3: Should I replace all cylinder head bolts at once, or can I reuse existing ones?
A: We strongly recommend replacing all cylinder head bolts with new ones whenever the cylinder head is removed. Cylinder head bolts are torque-to-yield (TTY) or stretch-type fasteners that permanently deform during initial tightening. Reusing them can result in inconsistent clamping force, leading to head gasket failure. Always install a complete set of new bolts for reliable engine performance.
