3804452 Lower Gear Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a Volvo Penta lower gear, from the Marine Propulsion group. It is an accounting line rather than a fittable part: the refundable charge raised against the old lower 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 3801452. 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 a lower gear, not a fittable part
• Credited back on return of the old lower gear
• Pairs with unit 3801452, three thousand below this core number

🔌 Function

Holds the refundable deposit raised against the old lower 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 lower gear itself turns the drive through to the propeller shaft at the foot of the leg.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the lower gear being exchanged
• A whine or growl from the lower unit that rises with the revs
• Grey or milky gear oil, with water sitting in the leg
• Metal particles clinging to the magnetic drain plug
• Vibration through the boat, or the propeller shaft running out of true

🛠️ Service Notes

• The deposit is refunded when the old lower 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 3801452, which is the item that actually ships
• 3804452, 3804453 and 3804454 are the three lower gear cores here, with nothing published to separate them - order by part number

📦 Condition

• Refundable core deposit - not a physical part
