FAQ

Q: What is the function of the S12501-51101 sleeve spacer in my Hino J05E engine?
A: The sleeve spacer sits between the cylinder block and the cylinder liner flange. Its primary function is to precisely control the liner protrusion (the height the liner sits above the block deck). Correct protrusion is critical for ensuring a proper seal between the cylinder head gasket, the liner, and the block. An incorrect spacer can lead to head gasket failure, coolant leaks, or loss of compression.

Q: How do I confirm this sleeve spacer fits my Komatsu SK200-8 excavator?
A: The Komatsu SK200-8 commonly uses the Hino J05E engine. The most reliable way to confirm fitment is to check the part number stamped on your existing spacer. If it reads “S12501-51101”, then this part is a direct replacement. You should also verify your engine serial number to ensure it falls within the production range for this specific spacer variant.

Q: Can this sleeve spacer be reused during an engine rebuild?
A: It is strongly recommended to replace sleeve spacers with new ones during a major engine overhaul. Spacers can become worn, distorted, or corroded over time, which can alter the critical liner protrusion measurement. Using a new, precision-machined spacer ensures that the cylinder liner sits at the correct height, preventing future sealing issues and ensuring the longevity of your engine rebuild.
