⚙️ 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

📦 Condition

• Brand new
• Supplied in original or equivalent packaging
