FAQ

Q1: Will this cylinder liner fit my Komatsu WA600 loader with an SA6D170E engine?
A: Yes, this liner (OEM 6240-21-2220) is specifically designed for the SA6D170E and SAA6D170E engines commonly found in the WA600 series. However, we recommend comparing the liner dimensions (outer diameter, inner diameter, and flange height) with your original part to confirm compatibility, as minor engineering changes may occur between engine serial number ranges.

Q2: What is the installation procedure for this cylinder liner?
A: Installation should be performed by a qualified diesel technician. The liner is typically pressed into the engine block using a specialized tool. Ensure the block bore is clean and free of debris. After installation, check the liner protrusion (standout) above the block deck to ensure it meets the engine manufacturer’s specifications. Always use new gaskets and O-rings during reassembly.

Q3: How should I store this cylinder liner before installation?
A: Store the liner in its original packaging in a clean, dry environment away from moisture and extreme temperature fluctuations. Apply a light coat of anti-rust oil to the machined surfaces if storing for extended periods. Avoid stacking heavy objects on top of the box to prevent distortion of the liner.
