22819604 Stud | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta stud weighing 0.050 kg, superseding part number 21456567 and covering its 11 TAD series applications. Thread condition at both ends determines the clamping load achievable.

⚙️ Key Features

• Stud
• 0.050 kg
• Supersedes part number 21456567
• Covers the 11 TAD series applications listed against the superseded number

🔌 Function

Provides a fixed threaded post screwed into the casting, so the mating component can be located and clamped by a nut without repeatedly cutting a bolt thread into the parent metal.

⚠️ Common Signs of Failure

• Nut will not pull up, or torque falls away as the stud pulls out of the casting
• Joint weeping or blowing where the clamping load has been lost
• Thread rusted, necked or stripped at the nut end
• Stud turning in the casting when the nut is slackened
• Stud snapped flush, leaving the stump to be extracted

🛠️ Service Notes

• Check the female thread in the casting before fitting a new stud, since a stud that pulled out usually means the parent thread has gone
• Renew the nut and any sealing washer at the same time rather than reusing a corroded set
