Brand Information

A genuine CAT 320-1291 is the correct SD7H15 build for these machines - right clutch, pulley, and oil spec - so it bolts up and cools as designed. Caterpillar builds machines, engines, and components for construction, mining, and power worldwide.

Installation Notes

If the old one failed internally, flush the system and replace the receiver-drier and expansion/orifice valve first - debris kills a new compressor fast.

How to Identify an OEM Part

- CAT logo and PT. NO. 320-1291 on the label, with R-134a / PAG100 / 24V printed.
- Confirm SD7H15 body, 130mm clutch, 8-groove serpentine pulley, 2-wire Deutsch.
- CAT sources these globally, so country of origin isn't the tell - the CAT logo and part number are. Match the PT number before buying.
