Description

CAT 101-1759 A/C Compressor - Genuine Caterpillar 24V A/C Compressor with Clutch for CAT Loaders and Dozers

The CAT 101-1759 is a genuine Caterpillar air conditioning compressor with a 24V clutch, Sanden SD7H15 style. It's the pump for the cab A/C - engine belt-driven, it compresses and circulates R-134a refrigerant through the system whenever the clutch is engaged.

Key Functions:

- Compresses and circulates refrigerant to run the cab A/C
- 24V clutch engages and disengages the compressor on demand

Fitment & Specifications:

- Application: CAT wheel loaders, dozers, track loaders, toolcarriers (924G-980G, D5M-D10, IT-series and more)
- Compressor: Sanden SD7H15, 24V clutch, 152mm, single-groove V-belt, 2-wire Deutsch

Verify fitment with us before ordering to ensure the correct part for your application.

Purpose of the Part

It's the pump that makes the cab A/C work. The engine drives it by belt, the clutch pulls in when cooling is called for, and it pumps refrigerant through the condenser, drier, and evaporator to cool the cab. If the compressor won't pump or the clutch won't engage, there's no cold air, no matter how good the rest of the system is.

Issue Symptoms / When to Replace

- No cold air or weak cooling in the cab
- Clutch won't engage (dead coil) or is slipping/burnt
- Bearing whine, knocking, or grinding from the compressor
- Seized compressor - squealing belt, smoke, or a thrown belt
- Oily residue and refrigerant loss at the shaft seal

Brand Information

A genuine CAT 101-1759 is the correct SD7H15 build for these machines - right clutch voltage, pulley, connector, and oil spec - so it bolts up and runs the cab A/C the way the factory unit did instead of fighting mismatched fittings or the wrong clutch. Caterpillar builds machines, engines, and components for construction, mining, forestry, and power generation worldwide.

Installation Notes

If the old compressor failed internally, flush the system and replace the receiver-drier and the expansion/orifice valve before fitting this one. Metal debris from a grenaded compressor will circulate and kill the new one fast - this is the number one cause of repeat A/C compressor failures.

How to Identify an OEM Part

- Look for the CAT logo and PT. NO. 101-1759 on the label, with the R-134a, PAG46/300cc, and 24V spec printed on it (as on this unit).
- "Made in China" on the label is normal - CAT sources these compressors globally. The CAT logo and CAT part number are what confirm it's genuine, not the country.
- Confirm the SD7H15 body, 24V clutch, single-groove pulley, and 2-wire Deutsch connector match your machine.
