FAQ

Q: How do I confirm this liner kit fits my Volvo D7D engine?
A: Verify the engine model stamped on your engine data plate. The D7D is commonly found in EC-series excavators and L-series loaders. Also, cross-reference your existing liner part number with our listed OEM numbers (04253772, 20450773, 04253777). If your part number matches any of these, this kit is the correct replacement.

Q: What installation precautions should I take?
A: Ensure the cylinder block bore is clean and free of debris. Lubricate the liner O-rings with clean engine oil before installation. Use a proper liner press tool to avoid distorting the liner. After installation, measure the liner protrusion above the block deck to ensure it falls within the manufacturer’s specified range (typically 0.02-0.10 mm).

Q: Can I install these liners without removing the engine from the equipment?
A: In most cases, cylinder liner replacement requires removing the cylinder head, oil pan, and pistons, which can be done with the engine in the chassis for many excavator and loader applications. However, we recommend consulting your equipment’s service manual for specific procedures. For marine or genset applications, engine removal may be necessary for proper access.
