875538 Big-End Bearing Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta big-end bearing kit in the standard grade, weighing 0.076 kg and listed for 2 applications across MB and MD series engines. It is one of three standard-grade big-end kits in this run and its short MB and MD listing is what identifies it — 875491 is the standard kit for MD and AQD engines, and 875747 the standard kit for D, TMD, TAMD and MD. Order by the application listing and by the grade stamped on the old shells, never by weight.

⚠️ Common Signs of Failure

• Oil pressure low or falling when hot

🛠️ Service Notes

• Check the application listing carefully — three standard-grade big-end kits appear in this run and they are not interchangeable
