3801142 Turbocharger | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured high pressure turbocharger, weighing 36.219 kg and listed for eight TWD applications from the TWD1643GE to the TWD1683GE. The reman catalogue records this number as the high pressure stage of a two-stage installation on every engine it appears against, with 3801141 as the low pressure partner on the TWD1643GE to TWD1645GE and TWD1663GE, and 3801754 as the low pressure partner on the TWD1672GE and TWD1673GE. The two stages are not interchangeable. At 36.219 kg it is the heaviest of the six turbochargers listed here. Supplied on an exchange basis: core deposit 3804142 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

⚠️ Common Signs of Failure

• Boost down and power loss with black smoke
• Whistle, siren or grinding from the turbo
• Blue smoke and oil consumption from failed seals
• Oil or soot at the joints between stages
• Shaft play or rub marks on the wheels

🛠️ Service Notes

• Establish which stage has failed before ordering - this is the high pressure unit, and the low pressure unit is a different part number
• Inspect the other stage and the interconnecting pipework for debris, as one failed turbo often damages the next
• Core deposit 3804142 is charged with this unit and refunded when the old one is returned - order both together
