872927 Alternator | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta alternator listed at 28V, 40A, from the Alternator, Charging, Electric Motor, Electric Drives group. It weighs 4.908 kg and covers 69 applications across the TAMD, AD, D, TMD, HS and KAMD series. The variant record gives its capacity as 24V/40A and lists it for the D1-20, D1-30, D2-40, D2-55A and D2-75A engines, and it is the 24 V alternator the accessories catalogue names for extra-alternator mounting kits 3583573 and 3884494. It consolidates three earlier numbers - 3803619, 849561 and 861598 - which were catalogued as an alternator, a mounting kit and a reconditioned alternator, so check whether the mounting hardware you need is still a separate order line.
