Applications:
Used on Caterpillar C11/C13 ACERT pre-2007 engine applications requiring a BA-922 42-tooth twin-piston flange-mounted compressor. The compressor supplies compressed air for the vehicle air brake charging system and is typically replaced when output decreases, leakage occurs, or internal wear affects air build time.
