REMOVE AND REPLACE XCS CONVEYOR CHAIN AND RAIL

REMOVE XCS CHAIN

1. Run the conveyor until the master link in the XCS chain comes up just under the offload end of the XCS

rail. Remove the master link from the chain and unthread the chain from all of the sprockets on the

conveyor end. Tie-wrap the free end of the chain to the machine frame to keep it from running away

under the oven.

2. Move to the onload end of the oven. Pull the XCS chain out of the rail and guide it into a clean container.

REMOVE XCS RAIL

1. Remove the XCS chain (see above).

2. Use a 3/16" hex key to remove the XCS rail capture bracket from one end of the machine.

3. Slide the XCS rail out of the other capture bracket and carefully remove it from the machine.

!!! Exercise extreme care when handling the XCS rail.

DO NOT let the rail bend or it may be permanently deformed.

Watch for height adjustment shims that may be installed at the gantry and intermediate positions.

Keep the shims away from the cell ducts. Do not swap these shims between locations.

INSTALL XCS RAIL

1. Visually inspect the rail for straightness and wear or damage to the chain guide surface.

2. Carefully place the rail in the XCS support nests

3. Install the XCS rail capture brackets on each end of the machine. Position the rear face of the capture

brackets flush with the rail end plates. Use care to not pinch the XCS rail with the capture brackets.

4. Slide the XCS rail back and forth in the rail capture brackets to test that there is no binding.

ALIGN XCS RAIL

1. Verify that the edge rail system is aligned and adjusted parallel within specification.

2. Use a gauge block and feeler gauges or a pair of calipers to measure the distance from the fixed edge rail

to the XCS rail near each of the feedscrew locations: (onload, offload, and intermediates). The measured

width at all feed screws must fall within a .020 (0.5mm) range.

3. If adjustment is required de-couple the wormgear boxes at the rear of the machine from the width adjust

shafts to allow turning one feedscrew at a time. Adjust feedscrews by hand to bring the XCS rail location

into specification then reconnect the width adjust shafts.

4. Verify XCS parallel in the spans between the feedscrew locations. The distance from the fixed edge rail to

the XCS rail midway between the feedscrew locations must be within .052 (1.32mm) of the measurement

at the feedscrews. XCS parallel can not be adjusted at the gantry locations. Replace the XCS rail if

variation is excessive.
