FAQ
Q1: Is this cylinder liner kit a direct fit for my Komatsu excavator? A1: This kit is specifically designed for engines with the model number 4D107. It is commonly used in Komatsu equipment. To confirm fitment, please check the engine nameplate on your machine. If the engine model is 4D107, this kit is compatible. If you are unsure, please provide your equipment model and serial number so we can cross-reference it.
Q2: What is included in the kit, and do I need to purchase other parts separately? A2: This kit includes the cylinder liners for the 4-cylinder 4D107 engine. For a complete engine overhaul, you will typically need to purchase additional parts separately, such as piston rings, pistons, cylinder head gaskets, and main bearings. We recommend replacing these components together to ensure optimal performance and longevity.
Q3: How should I install these liners to ensure a proper seal? A3: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the cylinder block bore. 2) Applying a thin layer of clean engine oil to the liner’s outer surface. 3) Using a proper liner press tool to gently insert the liner, avoiding force. 4) Checking the liner protrusion above the block deck using a dial gauge; it must be within the engine manufacturer’s specified range (usually 0.03-0.10mm). Incorrect protrusion can lead to head gasket failure.
