Komatsu Part COMPRESSOR ASS 207-27-63170

—

Product Overview

The 207-27-63170 COMPRESSOR ASS is a genuine Komatsu OEM replacement compressor assembly from the 207 prefix series. The compressor is a critical component in your machine's air conditioning and possibly its air brake or pneumatic system — it compresses refrigerant gas in the A/C circuit or generates compressed air for auxiliary systems. A failed compressor means no cab cooling in hot weather, creating uncomfortable and potentially unsafe operating conditions for the operator.

When to Replace

• The A/C system does not cool — the compressor clutch does not engage or the compressor runs but produces no cooling
• Unusual noise from the compressor — knocking, rattling, or grinding indicates internal mechanical failure
• The compressor clutch slips, makes noise, or fails to engage when power is applied
• Visible refrigerant oil leakage around the compressor shaft seal or housing joints
• The compressor has seized — the belt squeals and the pulley won't turn when the clutch is engaged
