REMOVE RAILS
1. Remove both edge rail chains (see above).
2. Use a 5/32" hex key to remove the shoulder bolts that retain both ends of each rail in the rail capture
brackets.
3. Use a 1/8 hex key to loosen the set screw in the top of the barrel nuts on all rail of the hangers.
4. With a 5/8 hex wrench remove all of the barrel nuts and thrust washers. The rail (with rail clamps still
attached) will drop down to rest on the mesh belt.

INSTALL RAILS
1. Visually inspect the rails for straightness and wear or damage to the chain guide surfaces.
2. Slide the appropriate number of rail clamps on each rail extrusion. Check that each clamp is properly
seated on the rail. Do not tighten the rail clamps, their position will be adjusted later in the installation.
3. Place the rail and clamp assemblies in the tunnel. Slide the rails under the hanger bars and place the
ends of the rails into the conveyor end plates. Position the rails all the way toward the onload end of the
machine and install the shoulder bolts through the capture brackets to retain the rails in the end plates.
4. Check that all hanger bars are in line above the rail clamps. The pinch bolts in the fixed rail hangers
should be left loose.
