130204 Stud | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta cooling-fan hub stud used in selected pusher- and suction-fan assemblies. The stud secures the fan to the hub and works with the specified flange nut to withstand centrifugal load, vibration and repeated thermal cycling. The stud is used with fan hub 3829537 and flange nut 990941 in confirmed TAD1140-TAD1142VE cooling systems. Six studs are commonly fitted, although the quantity must be against the parts list for your fan and hub.

🔌 Function

The stud forms a fixed threaded anchor point that locates and clamps the thrust fan assembly to its mounting face. Correct stud condition ensures the fan is held securely and runs true under continuous rotational load.

⚠️ Common Signs of Failure

• Stripped, galled or damaged threads preventing correct nut torque
• Corrosion or seizure making removal of the retaining nut difficult
• Stretched or bent stud causing fan misalignment or vibration
• Repeated loosening of the fan fastening under running load
• Fractured stud shank leaving part of the fastener in the mounting boss

🛠️ Service Notes

• Clean and chase the female thread before fitting so the stud can pull down square and to full depth
• Screw studs in with a proper stud installer or the double-nut method; gripping the plain shank with pliers or self-grips scores it and the nut will never seat or torque correctly afterwards
• Screw the stud home until it seats as the manual for your engine describes, and no further — a stud wound in hard to cure a slack thread will simply split the casting
• Renew studs that are stretched, necked, bent or corroded rather than reusing them; exhaust and manifold studs in particular are cheap next to the work of extracting a broken one
• Tighten the nuts to the torque figures and in the sequence given in the workshop manual for your engine, and where a stud passes into an oil or coolant space seal it as the manual specifies
