859028 Box Gasket | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta box gasket weighing 0.024 kg and listed for 41 applications across AD, D, TMD, BB, HS and MS series engines. No shaft diameter is published for it, and 859008 carries exactly the same fitment list, so the two cannot be separated by their listings - measure the shaft and order by part number against the installation's own parts list.

🚤 Compatibility

• Engine Family: AD, D, TMD, BB, HS, MS, TAMD, MD, KAD, KAMD
