Applications:
Used on Caterpillar-powered trucks and commercial vehicles requiring a TF-400 flange-mounted compressor with spline shaft and left-side inlet and outlet ports. The compressor supplies compressed air for air brake and auxiliary pneumatic systems and is typically replaced when air output decreases, leakage occurs, or internal wear affects system recharge.
