FAQ

Q1: How do I confirm this liner kit fits my specific Komatsu engine?
A1: The most accurate method is to match the engine model (e.g., 4D105) and the engine serial number (ESN). We recommend comparing the dimensions of your old liner or consulting your equipment’s parts manual with the provided specifications. Our team can assist with cross-referencing if you provide the ESN.

Q2: What is included in the “kit”?
A2: This listing is specifically for the cylinder liner/sleeve(s). Some kits may include necessary seals or gaskets; please confirm the exact contents with our sales team prior to ordering if a full gasket set is required for your overhaul project.

Q3: What are the critical installation steps to ensure proper performance?
A3: Proper installation is crucial. Key steps include: thoroughly cleaning the engine block bore, checking bore dimensions for wear, correctly installing the liner O-rings/seals with appropriate lubrication, ensuring the liner protrusion height is within specified tolerances using a dial gauge, and following the manufacturer’s torque sequence and specifications for cylinder head re-assembly.
