When the compressor goes, your operator is miserable — and miserable operators cost you productivity. The 84159489 compressor is a direct bolt-on replacement that gets cold air blowing again in under two hours.
The 84159489 A/C compressor is a direct fit for the following machines:
Also replaces superseded part numbers 87430122 and 87440388. If your current compressor shows any of these part numbers, this is the correct replacement.
When replacing the 84159489 compressor, always:
Is this the correct replacement for Case part 84159489?
Yes. This is a genuine OEM-spec compressor — 12V, ear mount, 1-groove 135mm clutch, MD head type. It is the exact same compressor that Case uses, matching part number 84159489 (and superseded numbers 87430122, 87440388).
Will this fit my Case 580M?
Yes. The 84159489 compressor is used across the entire Case 580M and 580N series backhoe loaders. Verify by checking your current compressor or your Case parts catalog for part number 84159489.
Is this an aftermarket compressor?
No. This is a genuine OEM-spec compressor — the same manufacturer that produces the compressor for the Case factory. It is OEM-quality because it IS the OEM part, just purchased through a different supply chain.
How much can I save vs. the CNH dealer?
CNH dealers typically quote $750–$920+ for this compressor. At $489, you're saving $260–$430+ per unit — and getting the exact same genuine OEM part.
Do I need to add oil to the new compressor?
The compressor ships with a small amount of oil. You may need to add additional PAG oil per your service manual specifications. Always measure what drains from the old compressor and adjust accordingly.
