Applications:
Used on Navistar HT530 and HT570 engine applications requiring a TF-550 metric-port compressor with left-side inlet and top outlet configuration. The compressor supplies air for heavy-duty service brake and auxiliary pneumatic systems and is typically replaced due to reduced air output, oil carryover, overheating, or internal wear.

A cross-reference listing means this part may be a suitable replacement for the listed part numbers. Always verify fitment before installation.
IMPORTANT INSTALLATION NOTES:
✔ Verify HT530/HT570 fitment, metric port configuration, left-side inlet, and top outlet orientation before installation
✔ Maintain minimum 2.5 GPM coolant flow and do not exceed 3000 RPM
✔ Use properly sized discharge, coolant, oil supply, oil return, air inlet, and unloader lines as specified
✔ Route the discharge line with proper downward slope, keep oil supply/return lines unrestricted, and drain reservoirs before service
✔ Suggested torque: cylinder head 440–500 in-lb; inlet/discharge fittings 175–225 in-lb; pipe plugs 35–270 in-lb; crankshaft castle nut 1200–1440 in-lb; crankshaft metric nut 2640–3048 in-lb
