# 23493469 Lower Gear | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta lower gear with a 1.69:1 ratio, weighing 89.36 kg and listed for nine applications across D series engines and DPH drives. It supersedes 22079940 - the ratio decreases in weight across this set, so weight alone is a poor guide.

## ⚙️ Key Features

-   Lower gear with a 1.69:1 ratio
-   89.36 kg
-   Supersedes 22079940
-   Listed for nine applications across D series engines and DPH drives
-   The middle of the three lower gears by both ratio and mass
-   Ratio 1.69:1 (Volvo assembly listing)

## 🔌 Function

Takes the drive from the vertical shaft through the 1.69:1 gear set and delivers it to the propeller shaft at the bottom of the leg.

## ⚠️ Common Signs of Failure

-   Whining or growling from the leg that rises with speed
-   Vibration through the hull that was not previously there
-   Milky gear oil or a falling oil level
-   Oil slick around the drive on the water
-   Worn bearings and pitted gear teeth found on strip-down

## 🛠️ Service Notes

-   The weight falls as the ratio rises across this set, so weight is a poor guide - 23493468 is the 1.59:1 gear and 23493470 the 1.85:1
-   Renew the shaft seals and gear oil and pressure test the leg before the boat goes back in the water
