🔧 Product Description

⚙️ Key Features

• 0.166 kg
• 53 applications across TAMD, AD, D, TMD, TD and MD engines

• Quantity varies by assembly, most commonly three

🔌 Function

Clamps the rocker arm shaft to the cylinder head and supports it between the rocker arms, holding the valve gear in line.

⚠️ Common Signs of Failure

• Knocking from the valve gear under load
• Rocker arm shaft able to lift or rock in the bracket bore
• Bracket bore worn oval or scored
• Cracks around the hold-down bolt hole or a stretched bolt
• Oil weeping from the bracket joint face

🛠️ Service Notes

• Count the brackets on your cylinder head before ordering — more than one is fitted per engine
• Inspect the rocker arm shaft at the same time; a worn bracket bore usually means a scored shaft, covered by 838642 or 838644
