Chief Chain-Driven Equipment Down: Seized Pin Won’t Press Out
Seized chain pins block restart on Chief chain-driven equipment during breakdown.
Why Chain Pins Seize
Line is down and pressure is on while the pin won’t move.
Torches risk chain damage and create serious safety hazards.
Corrosion, wear, and contamination pack out pins under repeated loads.
Why This Happens
Corrosion and contamination build up between pin and sidebar, locking movement. Wear from load cycling reduces clearances, allowing pack-out to seize pins solid. Thermal effects and debris accelerate binding, stopping the chain and halting equipment.
