The M10228 Counterbore Shim Cutter Plate is a precision-machined cutter plate designed for Caterpillar 3300 Series diesel engine blocks. Engineered as a direct functional equivalent to OEM part numbers PT-2400-13 and 5P-1659, this cutter plate is used during counterbore restoration procedures to accurately machine the liner seat for shim installation. Works with PT2250/M50139/M50133
On CAT 3300 Series engines, proper liner protrusion is critical to head gasket sealing, combustion integrity, and long-term engine durability. Over time, liner seats can become worn, fretted, or distorted, requiring counterbore machining and shim correction. The M10228 cutter plate provides stable, concentric guidance for the cutting tool, allowing technicians to remove material evenly and restore the counterbore surface to OEM specifications.
Manufactured for professional diesel rebuilders, machine shops, and fleet maintenance facilities, the M10228 ensures repeatable accuracy and reduces the risk of liner movement, coolant leakage, or premature head gasket failure during rebuild operations.
