191929 Hollow Screw | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta hollow screw is a cross-drilled hollow screw designed to clamp a banjo fitting while carrying fluid through the joint used in the engine fuel, oil or hydraulic banjo connection. It is manufactured to the original Volvo Penta dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it clamps a banjo fitting while carrying fluid through the internal passage. Selection must be confirmed by OEM part number 191929, the exact engine or product model, serial number and installed configuration.

🚤 Compatibility

• Engine Family: TMD, D, AQD, TD, TWD, TID, TAMD, THAMD, TAD

🔌 Function

Clamps a banjo fitting while carrying fluid through the internal passage. Clean the bore and cross-drillings, renew both sealing washers, align the banjo without stress and tighten to the specified torque.

⚠️ Common Signs of Failure

• Fluid leakage around the banjo sealing washers
• Restricted flow from blocked internal drillings
• Damaged threads, stretched shank or cracked head
• Air entry, pressure loss or poor fuel/oil delivery
• Repeated loosening or distorted banjo sealing faces

🛠️ Service Notes

• Check the through-passage is clear and clean before fitting; a blocked hollow screw starves whatever it feeds
• Always fit new sealing washers, one each side of the union where the original had them, and never reuse a crushed washer
• Hold the fitting or pipe end against turning as you tighten, so the line is not twisted and the union is not pulled out of position
• Tighten to the figure in the workshop manual for your engine — these seal by crushing the washer, not by force, and over-tightening splits the head or shears the shank
• Bring the system up to working pressure and check for weeps before closing the space up
