The M20107 Cummins Flywheel Housing Redoweling Kit is a precision-engineered alignment and restoration system designed to accurately re-establish the dowel bore locations between the flywheel housing and the engine block on Cummins heavy-duty diesel engines. When dowel bores become worn, elongated, or damaged due to vibration, improper installation, or housing misalignment, this kit provides a controlled, professional method to restore OEM geometry.
The M20107 kit mounts securely to the flywheel housing and block to guide technicians in re-drilling and re-boring the dowel pin holes to exact specifications. This ensures that the flywheel housing is perfectly centered and square to the crankshaft—critical for preventing clutch wear, transmission misalignment, pilot bearing failures, crankshaft thrust load issues, and premature component damage.
Designed for engine rebuilders, driveline repair shops, powertrain specialists, and fleet maintenance departments, this kit supports accurate realignment during in-frame or out-of-frame repairs on a wide range of Cummins applications including NT, NH, N14, and ISX-series platforms where dowel referencing is essential.
