## ⚙️ Key Features

-   0.836 kg
-   44 applications across the D series engines and HS series transmissions
-   Applies the clutch pack of discs 3886098, 3886099 and 3886100

## 🔌 Function

Converts transmission oil pressure into the clamping force that applies the clutch pack and engages the gear.

## ⚠️ Common Signs of Failure

-   Clutch slipping or engaging late even with correct oil pressure
-   Piston bore or skirt scored, or the piston sticking in its housing
-   Seal grooves damaged so pressure bleeds past
-   Pressure bleeding off with the gear selected
-   Clutch dragging in neutral because the piston will not return

## 🛠️ Service Notes

-   Renew the piston seals and the sealing ring 3886091 with the piston, or use sealing kit 3886285 or 3886286 for the group
-   Check the bore for scoring and that the piston moves freely before final assembly
-   Confirm the return spring 3886102 and retainer 3886101 are sound so the piston releases
