FAQ

Q1: How can I confirm this liner fits my Volvo D7D or Deutz BF4M1013 engine?
A: First, locate the existing part number on your old liner or engine block. Compare it to our listed OEM numbers: 20405909 (Volvo) or 04253771/04253772 (Deutz). If the numbers match, the liner is a direct fit. For additional verification, measure the liner’s outer diameter and height against your cylinder block specifications.

Q2: What installation precautions should I take?
A: Ensure the cylinder bore is clean and free of debris. Apply a thin film of clean engine oil to the liner’s outer surface before insertion. Use a proper liner installation tool to avoid distortion. After installation, check the liner protrusion above the block deck using a dial gauge to ensure it is within the engine manufacturer’s specified tolerance range.

Q3: How should I store unused cylinder liners?
A: Store liners in a clean, dry environment away from moisture and extreme temperature fluctuations. Keep them in their original packaging (plastic bag and carton) to prevent rust and physical damage. Avoid stacking heavy items on top of the cartons to maintain dimensional integrity. For long-term storage, consider applying a light rust preventative oil to the machined surfaces.
