Hutchinson Chain-Driven Line Down: Seized Pins Won’t Press Out
Your Hutchinson chain-driven equipment is stopped dead by frozen chain pins.
Why Chain Pins Seize Up
Corrosion and contamination pack around pins until they won’t move.
Wear from constant load cycling locks them solid under pressure.
The line stays down until those stuck pins are forced out.
Why This Happens
Corrosion builds between pin and sidebar, seizing the joint. Contamination and wear debris pack the clearance, preventing rotation. Repeated load cycling cold-welds surfaces, turning removable pins into permanent blocks that halt the entire chain.
