3802021 Turbocharger Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Reman turbocharger, listed in Volvo Penta's reman catalogue as the reman turbo for the TMD100C and TMD102A, weighing 16.37 kg and listed on our record for one TMD-series application. It supersedes 877028, catalogued earlier as a turbo, so an older parts list quoting that number leads here. The turbocharged aftercooled versions go elsewhere - the TAMD102D takes 3802100 - so the T or TA prefix is what decides. Volvo Penta reman turbochargers are rebuilt from a returned core against the current bill of material, with wear parts and anything outside the reman criteria replaced by new genuine parts, then tested and painted. It is supplied on exchange: core deposit 3805021 is charged alongside it and refunded once the worn turbo is returned, and the core may go back after the new one is fitted and the engine is running again.

• The old number 877028 still identifies this unit on earlier parts lists
