## ⚙️ Key Features

-   Supplied as a matched set
-   3.066 kg
-   93 applications across the AQ, TMD, BB, MS, B and AD families

## 🔌 Function

Transmits drive between shafts through meshing teeth, changing the direction and the ratio of the rotation on the way.

## ⚠️ Common Signs of Failure

-   Whine, howl or growl from the drive that changes with load
-   Clonk on take-up when engaging ahead or astern
-   Metal particles or glitter in the drained oil
-   Teeth found chipped, spalled or worn to a hooked profile
-   Backlash that has grown noticeably since the last service

## 🛠️ Service Notes

-   Fit the gears as a set - mixing a new gear with an old mating gear puts the new teeth onto a worn contact pattern and both then fail quickly
-   Renew the bearings and shaft seals at the same time, and check the oil for the water or debris that caused the original failure
-   Set the backlash and contact pattern to the manual figures rather than assuming a new set is correct as it comes
