Unicla Air Conditioning Compressor 24V Direct Mount US150 Part No. CXU7375

The Unicla US150 air conditioning compressor is a 24V direct mount unit supplied under Part No. CXU7375. It is listed as a GM Horizontal Pad fitting type with an 8 groove pulley section, a 133mm clutch diameter, and a weight of 9kg, so it is intended for specific heavy equipment applications where those mounting details match.

This compressor is identified with OEM number 4301 and Original Equipment Number 4301, and it carries a one year warranty. The unit is supplied as a single each, with a note to use O ring ORX017 x 2, which is important when comparing the compressor to the existing system connections before purchase.

Application details supplied with this unit include Caterpillar dump trucks 773, 775F/G, 777F/G, 789D/F and 797B/F from 01/2011 onward, plus Caterpillar excavators 325D and 385B 3456 from 01/1990 onward, and Caterpillar graders 12H, 12K, 12M and 140M from 01/2001 onward. Those application notes should be checked alongside the part number and mount style, not relied on by model name alone.

Application and Buying Notes

Before ordering, compare the compressor mounting and pulley details on the machine with this unit’s direct mount, GM Horizontal Pad fitting and 8 groove pulley section. The 24V electrical specification and 133mm clutch diameter are key checks, especially on heavy equipment systems where similar-looking compressors can differ in mount pattern or pulley setup.

The listed OEM number 4301 and Part No. CXU7375 are the most useful identifiers for confirming you have the correct replacement. If your current compressor is marked differently, or if the existing plumbing uses a different seal arrangement, stop and verify before buying. This unit is supplied with a note for O ring ORX017 x 2, so matching the connection style matters.

The application list covers specific Caterpillar dump truck, excavator and grader models, but it should be treated as a guide only. Model families such as 773, 775F/G, 777F/G, 789D/F, 797B/F, 325D, 385B 3456, 12H, 12K, 12M and 140M can share naming across different build periods, so the safest check is always the part number, voltage, mount type and pulley section together.

At 9kg, this is a substantial compressor intended for commercial and earthmoving use rather than light vehicle applications. Make sure the receiver/drier, hoses, brackets and electrical connection on the machine are compatible with the existing system layout. If the old unit failed from contamination or seizure, it is also sensible to inspect the rest of the air conditioning circuit before fitting a replacement compressor.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number CXU7375 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Additional published details for cross-checking include Product Group 2 AC COMPONENTS, Part No. CXU7375, Brand UNICLA, Description Unicla Air Conditioning Compressor 24V Direct Mount US150, Body Number US150, Compressor Mounting Direct Mount, Original Equipment Number 4301, Series US150, Voltage 24, Dust Cover Y/N No.

Unicla Air Conditioning Compressor 24V Direct Mount US150. Part number CXU7375 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Pulley configuration is 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number CXU7375, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a air conditioning compressor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CATERPILLAR 120H, CATERPILLAR 120H 2007, CATERPILLAR 12H, CATERPILLAR 12H 2004. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by matching Part No. CXU7375, OEM number 4301, 24V direct mount configuration, GM Horizontal Pad fitting type, 8 groove pulley section and 133mm clutch diameter against the existing unit and machine application details.
