The M10229 Counterbore Shim Cutter Plate is a precision machining Cutter Plate engineered specifically for the Caterpillar C10, C11, C12, and C13 engine block platforms. Functioning as a direct replacement for OEM part numbers 159-9402 and PT-2210-50, this cutter plate is designed to guide and secure the cutter bit during refurbishment of the liner seat counterbore and shim installation process.
During heavy-duty engine rebuilds where liner seats have worn beyond specification, become irregular, or require shim installation, a properly machined counterbore section is critical for achieving correct liner protrusion and deck sealing. The M10229 plate ensures accurate, concentric and controlled material removal—helping prevent gasket failures, liner misalignment and premature engine wear.
Rebuilders, machine shops and fleet service centers will value this fixture’s compatibility with cutter bit M10229-5 and its engineered precision tailored for CAT C-series blocks.
