McLanahan Chain-Driven Equipment Down – Seized Pin Won't Press Out
Your McLanahan chain-driven line is stalled because seized pins block restart.
Corrosion, Wear, Contamination
Downtime mounts while pins refuse to budge under standard pressure. Torch attempts risk fire and injury in urgent repairs. Corrosion, wear, and contamination lock pins solid, halting production until removed.
Why This Happens
Pins seize when corrosion builds up, wear enlarges clearances then tightens, or contamination packs in and hardens under load cycling. This blocks normal pin movement, stopping chain articulation and equipment restart. The result is extended breakdowns and safety hazards during forced removal.
