3BUS 208 000 R1301182 Maintenance Procedures
1. Inspect the seal belts for evidence of wear or cracks. Replace belts that have
evidence of wear or cracks.
2. Inspect the seal belt rollers for evidence of cracks or wear.
3. Inspect the spring tension on the seal belt rollers. The roller assembly should
exert some downward force when manually lifted. If this does not happen, the
roller assembly should be replaced.
If the seal belt tension is uneven, adjust the tension of the seal belt as follows:
1. Loosen the seal belt clamp adjustment corresponding to the side that is elevated
by a slight amount.
2. Tighten the clamp when finished.
If the belt tension is too tight at both sides:
1. Loosen the seal belt clamp adjustments and pull the seal belt evenly in the cross–
machine direction to result in a uniform decrease in tension.
2. Tighten the clamps when finished.
If the belt tension is too loose:
1. Loosen the seal belt clamp and pull the seal belt through the clamp in the cross–
machine direction evenly to result in a uniform increase in tension.
2. Tighten the clamp when finished.
Head Separation and Limit Switch Inspection
