McLanahan Chain Equipment Down: Seized Pin Won't Come Out
Your McLanahan chain-driven equipment is stopped cold by seized pins that won't press out.
Corrosion, wear, contamination cause seizure
Downtime is killing production while the line stays blocked. Safety risks spike when torches or hammers force stuck pins. Corrosion, wear, and contamination lock pins tight, stalling restarts and repairs.
Why This Happens
Chain pins seize when corrosion builds up, wear widens clearances for debris pack-out, or heavy loads and contamination harden material between pin and bushing. This binds the joint completely. Result: pins won't move, halting equipment and forcing unsafe, time-wasting fixes.
