Maintenance Procedures
Discharge Conveyor Chain Tension - Check/Adjust Uneven Sag
Discharge conveyor chain is automatically tensioned. Check chain sag monthly or every 150 service
hours to verify proper function of tensioner. Inspect chain for wear. Maintain chain sag at 4-9"
(102-229 mm) at measurement point shown in detail view B .
1. Start engine and run 2-3 minutes. Open discharge conveyor cleanout door. Refer to
"Discharge
Conveyor Cleanout" , page 3-55 .
2. Lower conveyor. Run conveyor chain for 2-3 minutes.
3. Run chain forward until a chain slat is just off edge of floor plate as shown in detail view A .
4. Bump chain forward/reverse until chain sag is no longer increasing. The final chain bump must
be in reverse for maximum chain sag to occur. Do not allow a chain slat to ride up onto floor
plate.
5. Turn engine off and remove ignition key.
6. At midpoint of cleanout door, measure chain sag from bottom of frame flange to bottom of slat as
shown in detail view B. Measure both sides of chain to ensure chain sag is even from side to side,
+/- 1/4" (6 mm).
• If chain sag is out of range, manually run an auto-adjust tensioning cycle. Refer to "Manually
Starting an Auto-Adjust Cycle" , page 5-16 .
• If chain sags unevenly from left to right, refer to
"Discharge Conveyor Chain - Adjust Uneven
Sag" , page 5-22 .
Contact a Weiler dealer if chain sag remains out of range or uneven after adjustment.
7. Check chain for wear. Refer to "Chain Checklist" , page 5-22 . Contact a Weiler dealer if chain
shows significant wear or stretch.
WARNING
Contact with hot asphalt can cause severe burns.
Stay clear when opening cleanout door.
