7. Turn the thrust washer under each barrel nut by hand to verify that all of the nuts are in contact with the
hanger bars.
NOTE: It is very important to the function of the hanger system that all barrel nuts carry
some load. The installed height of the gantries can vary slightly due to tolerance stack-
ups in the oven sheet metal subassemblies so it is sometimes necessary to adjust the
height of the rail in the hangers. Equal height of all hangers is especially important on
1240 machines where two pairs of supports are only separated by one cell.
If adjustment is needed use the intermediates as the known height reference and make adjustments to the
hangers at the gantries.
To lower the rail height in a hanger loosen the jam screws then unscrew both barrel nuts an equal amount,
up to three full turns of the barrel nuts maximum.

To raise the rail height add one or two thrust washers under both barrel nuts, fully seat the nuts, then
unscrew them equal amounts to fine tune as necessary. There is only enough clearance for two additional
thrust washers, do not attempt to use more than three.
When adjustments are complete tighten the jam screws to lock the barrel nuts in place.
8. After aligning the fixed rail and setting parallel (see next section), temporarily remove the fixing screws
from the onload end capture brackets and check for free movement of both rails in the hanger brackets.
The barrel nuts should slide in the hanger bar slots without catching or tending to twist the hanger
assembly around its mount.

ALIGN AND PARALLEL EDGE RAILS
ALIGN FIXED RAIL
1. The fixed rail is adjusted straight using a string and three small metal plates of identical thickness.
2. Clamp one of the small plates to each end of the fixed rail and stretch a string between them.
3. Use the third plate to gauge the position of the rail at each gantry and intermediate.
4. Adjust the position of the intermediate and gantry fixed rail hangers on the cross bars to straighten the rail
relative to the string.
