FAQ

Q: How can I confirm this gasket kit fits my specific Komatsu machine?
A: This kit is designed for the 6D155 engine platform. To confirm fitment, please check your engine nameplate for the model designation “6D155” and compare your existing gasket part numbers with the OEM numbers listed (6128-K1-9901 or 6128-K2-9901). For excavator applications, common models include PC200, PC210, and PC220 series equipped with this engine. If unsure, contact our technical support with your machine model and serial number for verification.

Q: Does this kit include head gaskets, valve stem seals, and other critical components?
A: Yes, this is a full gasket kit containing all upper gaskets (cylinder head gasket, intake/exhaust manifold gaskets, valve cover gasket) and lower gaskets (oil pan gasket, timing cover gaskets, front/rear main seal). It also includes valve stem seals, O-rings, and other sealing components required for a complete engine overhaul. Please refer to the included parts list for exact contents.

Q: What is the recommended installation procedure for this gasket kit?
A: Proper installation is critical for performance. We recommend: 1) Thoroughly clean all mating surfaces to remove old gasket material and debris. 2) Check cylinder head and block surfaces for flatness using a straightedge. 3) Apply thread sealant to head bolt threads and lubricate bolt shoulders. 4) Follow Komatsu factory torque specifications and tightening sequence for the 6D155 engine. 5) After initial start-up, re-torque head bolts if specified by the engine manual. Always use new gaskets and never reuse old components.
