Seal Belt Tension Inspection

Inspect the seal belts. The seal belts must have enough tension so that a seal is

present along the length of the platform but not too much so that the carriage seal

belt roller is deflected up causing a break in the cable seal. Refer to Figure 9-4.

The tension on the seal belts must be even on each side of the belt. If this is not the

case, the carriage seal belt roller will be deflected up on one end.
