3805427 Lower Gear Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a lower gear, in the Marine Propulsion group. It is the refundable charge raised against the old lower gear when the exchange unit is bought, and it comes back once the worn lower gear is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3802427, which is the number to quote for the component itself. The other lower gear core listed here is 3805457, and nothing published against the two separates them, so order the number that matches the lower gear actually coming off. The upper gear cores in this run are 3805386 and 3805426, and they are separate deposit lines.

⚙️ Key Features

• Core deposit line, not a lower gear you can fit
• Belongs with the exchange unit, part number 3802427
• Refunded when the old lower gear is returned
• Not separable from lower gear core 3805457, so order by part number
• Marine Propulsion group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the lower gear itself turns the drive through a right angle onto the propeller shaft and carries the thrust the propeller generates.

⚠️ 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
• Whining or growling from the lower unit that rises with the revs
• Water in the gear oil, or oil weeping past the seals into the water
• Play or roughness felt at the propeller shaft when it is turned by hand
• Crunching on the shift, jumping out of gear, or drive that will not take up

🛠️ Service Notes

• The charge is refunded when the worn lower gear is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3802427
• Drain and inspect the gear oil for water and metal before condemning the unit, and renew the shaft seals and gaskets disturbed on removal

📦 Condition

• Refundable core deposit - not a physical part
