The M20108 Cummins Flywheel Housing Dial Indicator is a precision measurement instrument designed for accurately checking flywheel housing alignment, crankshaft centerline deviation, and housing runout on Cummins heavy-duty diesel engines. Proper flywheel housing alignment is critical for preventing transmission input shaft wear, clutch engagement issues, vibration, and premature drivetrain component failure. The M20108 provides technicians with the precise measurement capability required to maintain OEM-spec accuracy during engine assembly, overhaul, or drivetrain service.
This professional tool attaches securely to Engine and allows technicians to measure radial and axial runout with exceptional accuracy. By verifying housing alignment relative to the crankshaft centerline, the M20108 helps ensure that the transmission mates squarely to the engine, reducing driveline stress and improving long-term reliability.
Built for engine rebuilders, dealership service departments, and fleet maintenance facilities, the M20108 is engineered from heavy-duty materials to withstand continuous use in demanding shop environments. It is essential whenever a flywheel housing is replaced, machined, or suspected of misalignment.
