⚙️ Key Features

• Grey finish
• Supersedes 852869, earlier catalogued as a fork
• 3.856 kg
• 80 applications across the AD, D, AQ, TMD, B and BB families

🔌 Function

Carries the drive's suspension load through its two arms, letting the assembly pivot between them while taking the thrust and steering loads into the structure.

⚠️ Common Signs of Failure

• Knocking or clonking from the drive as load or steering direction reverses
• Visible play at the pivot between fork and drive
• Cracks in the fork, most often at the arm roots or around the pivot bosses
• Pivot bores worn oval, or the bushings worn through
• Corrosion pitting or exfoliation on the fork arms

🛠️ Service Notes

• This is a load-carrying suspension component - a cracked fork should be taken out of service rather than watched, and the crack is usually at an arm root or pivot boss
• Renew the pivot bushings and pins at the same time and check the pins for stepping
• Grease the pivots on assembly and check for free movement over the full range before the boat goes back in
