FAB Heavy Parts carries A/C compressor options for a range of manufacturers, including Caterpillar, Kubota, Bobcat, John Deere, CASE, Komatsu, and Doosan. Use the listed part number and equipment application to narrow your search for the right replacement.

A/C Compressors for Different Equipment Applications

The collection includes compressors for a variety of machines and vehicles. Examples include Caterpillar compressor 345-4547 for selected D-series compact track loaders and skid steer loaders, Kubota compressor RD451-93900 for selected tractor applications, and Bobcat compressor 7363374 for selected S-series, T-series, and E-series equipment.

Product types and configurations vary. Some listings are for complete A/C compressors, while others include related components such as a receiver drier or condenser. Certain products also specify details such as voltage, compressor model, clutch diameter, or pulley groove count. Review the individual listing for the specifications and components supplied with that particular product.

What to Check When Replacing an A/C Compressor

The air conditioning compressor circulates refrigerant through the vehicle or equipment's A/C system. A failing compressor can contribute to poor cooling, unusual noise, or system malfunction, although these symptoms can also have other causes.

Before selecting a replacement, compare the original compressor's part number with the numbers listed on the product page. Confirm the equipment make, model, and application, then compare relevant configuration details. Depending on the compressor, these may include operating voltage, clutch diameter, pulley groove count, mounting points, and refrigerant-system connections. Do not assume that compressors with similar appearances or the same brand name are interchangeable.

Frequently Asked Questions

How do I find the right A/C compressor for my tractor or excavator?

Start by checking the part number on your original compressor, then compare it with the number and equipment applications on the product page. Please also confirm your machine's make, model, and relevant configuration details. If you're unsure which listing matches your equipment, please share the original part number and machine model with us so we can help review the available information.

Can I use the same A/C compressor on different models from the same manufacturer?

Not necessarily. Compressors used by the same manufacturer can have different electrical specifications, mounting points, clutch configurations, or pulley arrangements. Please check the specific part number and listed applications before ordering rather than relying on the brand name alone.

What does 12V or 24V mean in an A/C compressor?

The voltage identifies an electrical specification of the compressor assembly, particularly the clutch where applicable. Please compare it with your original unit and equipment requirements. A matching voltage alone does not establish compatibility, so the part number and other configuration details also matter.

Does an A/C compressor come with a receiver drier or condenser?

Not always. Some listings specify a compressor only, while others explicitly mention additional components. Please review the product title, description, and included-parts details before ordering. If the listing does not clearly identify what's included, contact us with the product link so we can help clarify it.

I've replaced my A/C compressor, but my equipment still isn't cooling. What should I check?

Poor cooling can have several causes, including refrigerant leaks, electrical faults, airflow restrictions, or problems elsewhere in the A/C system. Please have the system diagnosed by a qualified technician rather than assuming the compressor is the only fault. Compressor replacement may also require correct refrigerant recovery, oil management, contamination checks, and system-specific servicing procedures.
