🔌 Function

Clamps a major propulsion joint, distributing clamping load evenly around its circumference to hold the mating faces together and sealed. Even tightening around the ring is what maintains that uniform load.

⚠️ Common Signs of Failure

• Cracking around fastener holes or across the ring section
• Corrosion or pitting on the clamping face
• Distortion leaving uneven contact with the mating face
• Fasteners repeatedly loosening, or fretting marks at the joint
• Water ingress or leakage at the clamped joint

🛠️ Service Notes

• Tighten evenly in the specified sequence - uneven load on a ring this size distorts the joint
• This part weighs 34 kg; plan the lift and support before removal
