DT466 530 Counterbore Shim cutter plate with 4.589 Bore. Fits Porta-Tool PT2250 & M50133
Similar to PT 2200-95, ZTSE-25144-AThe M50125 Counterbore Shim Cutter Plate is a precision engine machining component engineered for Navistar International DT466 and 530 diesel engines. Designed as a direct functional equivalent to PT-2200-95 and ZTSE-25144-A, this cutter plate is used during counterbore service to machine the counterbore ledge accurately so corrective shims can be installed and proper cylinder liner protrusion restored.
On DT466/530 platforms, counterbore wear or distortion can lead to insufficient liner protrusion, head gasket failure, coolant seepage, and combustion sealing issues. The M50125 provides the correct cutting geometry to remove material evenly and concentrically, creating a clean, flat seating surface for shim installation. When used with a compatible counterbore cutting system and depth-setting tools, it helps technicians achieve OEM-level liner height control without replacing the engine block.
Built for professional diesel shops, fleet maintenance facilities, and engine rebuilders, the M50125 cutter plate is manufactured from durable materials suitable for repeated machining cycles in demanding environments.
Key Features & Benefits
-
Engine-Specific Application: Designed for Navistar DT466 & 530 engines to ensure proper counterbore geometry.
-
OEM-Equivalent Compatibility: Replaces/alternates with PT-2200-95 and ZTSE-25144-A cutter plates.
-
Precision Machining: Produces a flat, concentric counterbore surface for accurate shim placement.
-
Supports Correct Liner Protrusion: Helps restore factory liner height specifications and head gasket sealing.
-
Professional-Grade Durability: Built for repeated use in heavy-duty diesel engine rebuild operations.
Typical Applications
-
Counterbore repair on Navistar DT466 and 530 engines during overhaul or in-frame service.
-
Preparation of counterbores for shim installation to correct liner protrusion.
-
Use with compatible counterbore cutting tools, pilots, and set masters in professional machine shops and diesel rebuild facilities.
Why It Matters
Counterbore condition directly determines liner height and head gasket reliability. An uneven or worn counterbore can cause repeat gasket failures and costly downtime. The M50125 Counterbore Shim Cutter Plate enables controlled, accurate material removal so shims can be installed correctly—helping technicians restore liner protrusion, improve sealing integrity, and extend engine service life.
