How to Measure the SAE Flywheel Housing Size of an Industrial Engine

Jeff & Jim tackle a common question that we receive here at Palmer Johnson Power Systems, “How do you measure the SAE flywheel housing size of an industrial engine?” They provide instructions on attaining the key measurements, flywheel housing pilot bore, and the pilot bearing bore depth.

The SAE size of an industrial engine flywheel housing is used in several drivetrain components in industrial off-highway equipment, such as gearboxes, pump drives, transmissions, transfer cases, couplings, and more.
