3802457 Lower Gear Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured lower gear from the Marine Propulsion group, weighing 278.05 kg and listed for 6 applications across D series engines and IPS pod drives. It supersedes part number 3801876. At better than a quarter of a tonne this is the heaviest item in its range by a wide margin, so it moves on a pallet with lifting gear rather than as a parcel. This unit is supplied on an exchange basis: core deposit 3805457 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

🔌 Function

Carries the drive down from the upper unit through the bevel gears to the propeller shafts, and takes the whole thrust of the propellers into the hull.

⚠️ Common Signs of Failure

• Whine, growl or rumble from the drive that rises with engine speed
• Metallic glitter or a milky look in the drained gear oil
• New vibration felt through the hull under load
• Oil weeping from the housing joints or shaft seals
• Pitted, chipped or spalled gear teeth found once the unit is split

🛠️ Service Notes

• The weight rules out normal parcel delivery and hand carrying - arrange pallet freight and lifting gear at both ends before the unit arrives
• Supplied as a remanufactured exchange unit, so the old gear goes back as the core
• Renew the oil, seals and gaskets disturbed on removal, and check the propeller shafts, hubs and blades for the damage that may have loaded the gears in the first place
• Core deposit 3805457 is charged with this unit and refunded when the old one is returned - order both together
