🔧 Product Description

A high-strength stud used to locate and clamp the flywheel housing on 8.1-litre IPS gasoline installations. One end remains anchored in the engine or housing and the exposed thread accepts the nut, preserving alignment while avoiding repeated wear of the parent casting thread.

⚠️ Common Signs of Failure

• Loss of alignment or retention
• Abnormal noise, vibration or movement
• Leakage or damage at adjoining parts

🛠️ 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
