Break Seized Chain Pins Fast — No Torches. No Hammering.
Resin-packed drag conveyor pins seized solid and stopped your OSB line cold.
Why Pins Seize in Sawmill OSB
Resin, dust, and heat pack tight around chain pins and lock them in place.
The seized pin halts the drag conveyor and bleeds production by the minute.
Only hydraulic force clears resin-loaded pins fast and safely without a torch.
Why This Failure Happens
Resin and fines infiltrate WH132, WDH159, and ER864 joints and cure into a rigid mass. Heat and thermal cycling expand sidebars and bushings until the pin galls tight. Load shocks then drive the seized joint deeper, locking the conveyor and stalling OSB throughput.
