Illustration 1 g00586236
Inspect the slack of the elevator chain. Inspect the slack at the widest space that is between the arrows. The upper arrow is located at the lower edge of the frame assembly for the elevator. The lower arrow is on the upper side of the elevator chain. The widest space will be halfway between the upper sprocket and the lower idler. The slack in the elevator chain should be between 127 mm (5.0 inch) and 229 mm (9 inch). Adjust the elevator chain when the distance between the arrows exceeds 229 mm (9 inch).The elevator chain should be inspected for wear. Measure the length of 10 chain links. Replace the elevator chain if the 10 links measure more than 1090 mm (43 inches).Refer to Disassembly and Assembly, SENR5634, "Chains and Flights (Elevator) - Remove" for further information.Note: Failure to replace a worn elevator chain will result in excessive wear to the drive sprockets.Adjust the Elevator Chain
