21679632 Drill jig | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta special tool 21679632, listed at 6.804 kg. Volvo's own special tools catalogue identifies it as a drill jig and publishes its applications: the D4 and D6 ranges, from D4-175I-G through the D4-300 and D4-320 variants and across the D6-280 and D6-310 variants. A drill jig holds the drill on the correct centre and square to the face, so the holes it produces repeat exactly rather than depending on the operator's eye.

⚙️ Key Features

• 6.804 kg
• Designated a drill jig in Volvo's special tools catalogue
• Published for the D4 and D6 ranges
• Controls hole position and drilling geometry rather than being drilled by hand

🔌 Function

Positions and guides the drill so every hole is cut on the specified centre and square to the face, giving a repeatable pattern.

⚠️ Common Signs of Failure

• Guide bushes worn oval, letting the drill wander
• Jig no longer sitting flat or square on the face
• Locating pins or dowels worn, so the pattern shifts between jobs
• Distortion or a bow after being clamped too hard
• Corrosion on the locating surfaces

🛠️ Service Notes

• Check the guide bushes before drilling — a worn bush puts every hole off centre by the same amount and the error is easy to blame on the casting
• Clamp the jig solidly and confirm it is seated flat before the drill goes in
