3804419 Upper Gear Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a Volvo Penta upper gear, from the Marine Propulsion group. It is an accounting line rather than a fittable part: the refundable charge raised against the old upper gear when a replacement is supplied on exchange, credited back once that worn unit is returned. Ordering it supplies nothing in itself. It is raised against unit 3801419. Core numbers in this series run three thousand above the unit they belong to, so the deposit and the unit are read as a pair.

⚙️ Key Features

• Refundable core deposit on an upper gear, not a fittable part
• Credited back on return of the old upper gear
• Pairs with unit 3801419, three thousand below this core number

🔌 Function

Holds the refundable deposit raised against the old upper gear when a replacement is bought on exchange, and releases it as a credit when that unit is returned. It does no mechanical work. The upper gear itself takes the drive from the engine and turns it down through the top of the transom unit.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the upper gear being exchanged
• Whining, howling or rumbling from the upper unit that changes with load
• Gear oil turned grey or milky, showing water has got in
• Metal picked up on the magnetic drain plug
• Backlash or play felt in the drive, or engagement gone reluctant

🛠️ Service Notes

• The deposit is refunded when the old upper gear is sent back, so return it complete and as it came off - the credit depends on the core being fit to rebuild, and a stripped or broken-up unit can lose it
• Ordering this line on its own supplies no part. It has to go on the order alongside unit 3801419, which is the item that actually ships
• 3804419, 3804450 and 3804451 are the three upper gear cores here, with nothing published to separate them - order by part number

📦 Condition

• Refundable core deposit - not a physical part
