3804947 Compressor Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a compressor. It is the refundable charge raised against the old compressor when the exchange unit is bought, and it comes back once the worn compressor is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3801947, which is the number to quote for the component itself. It is the only compressor core in this block, so there is nothing here to confuse it with.

⚙️ Key Features

• Core deposit line, not a compressor you can fit
• Belongs with the exchange unit, part number 3801947
• Refunded when the old compressor is returned
• The only compressor core in this block

🔌 Function

As a line item it carries the refundable core charge on the exchange; the compressor itself is driven by the engine and raises the pressure of the gas passing through it to feed the system it serves.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the compressor being exchanged
• Pressure slow to build, or never reaching the level it used to
• Rattling, knocking or squealing from the compressor that follows engine speed
• The unit running hot, with oil carried over into the delivery line
• Weeping from the shaft seal or the joints, and belt wear or slip at the drive

🛠️ Service Notes

• The charge is refunded when the worn compressor is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801947
• Check the drive belt, the mounting and the delivery line before the exchange unit goes on, since a slipping drive or a restricted line will work the replacement just as hard

📦 Condition

• Refundable core deposit - not a physical part
