Check Pickup Slip Clutch Torque (MegaWide™ Plus Pickup)

For beginning of season service, ensure that the slip clutch is free to slip. It is not necessary to check clip clutch torque values.

Excessive pickup clutch slipping can be caused by improper pickup height, gauge wheel, or float spring adjustments.

Clutch must slip within specifications when slipped at the gear case output hex shaft. As the clutch wears, it can gradually transmit less power due to slipping, and feeding performance can be unsatisfactory.

New Clutch	Slip	290—420 N·m (214—310 lb·ft)

To check slip clutch torque:

1. Ensure that gate is locked. If gate is raised and not locked while performing this procedure, the gate could close suddenly causing injury or death.

   If the slip clutch does not slip at 420 N·m (310 lb·ft), the clutch is not working correctly. Replace slip clutch to avoid possible damage to pickup.

8. Use a 1 in drive breaker bar or weld a heavy 1-1/4 in socket to a 10 x 76 x 914 mm bar to hold shaft in place. Smaller breaker bar or wrench can break or bend.

   Install a tool on reel or auger or rotor shaft to prevent the shaft from rotating counterclockwise.

9. To avoid chain from jumping the sprocket while trying to slip the clutch:

   • Tighten the chain.
   • Make sure idler arm pivots freely and is spring loaded.
   • Add alignment marks (or tape) on the clutch sprocket and on the hex shaft going through the clutch. These marks can determine whether the clutch slipped or the chain jumped during each slip test.
   
   

10. Rotate the output shaft and slip clutch a minimum of four ratchets before recording measurements.

11. To identify clutch specifications:

    • Set a click-type torque wrench to 290 N·m (214 lb·ft)
    • Install the torque wrench, with extension, on the hex output shaft (A) at the left-hand side of baler.
    • Turn wrench clockwise. Wrench must click before clutch slips. Repeat procedure three times.
    • Set the torque wrench to 420 N·m (310 lb·ft)
    • Turn the wrench clockwise. Clutch must slip before wrench clicks. Repeat procedure three times.
    
    

12. If the clutch slips below the following specifications, replace the complete clutch.

13. Never use any type of tool or wrench on shafts while tractor engine is operating. Always remove tools from the shaft as soon as procedure is finished.

    Remove tools from shafts.

14. Install washers and quick-lock pin or cap screw.

15. Install right-hand shields.

16. Close left- and right-hand doors.

17. Unlock and close the gate using tractor hydraulics.
