Kickout Solenoid Adjustment Procedure
Use caution to avoid possible personal injury when adjusting the bucket positioner and lift kickout. Apply the parking/emergency brake and block the tires to prevent sudden movement of the machine.Keep personnel off the machine. Clear the area when working under or around the bucket linkage. With the bucket raised, proper support must be provided for the bucket and/or the linkage.
Use Illustration 1 for 992C or 988B Loaders. Use Illustration 2 for 980C, 966D or 950B Loaders. Use Illustration 3 for 936 Loaders.Use the procedure that follows to adjust the control lever linkage.
1. Be sure the lift kickout and bucket positioner are correctly located.2. Raise the bucket as high as it will go and tilt it back to the limit of its travel. This is to make sure that the kickout solenoids will be energized (have electrical power to pull the solenoid plunger in) when the key switch is on. Use blocks or jack stands to support the lift arms and bucket in this position.3. Be sure the key switch is on to energize the kickout solenoids. Each solenoid plunger should be pulled into its solenoid body. Measure the distance between the top of the solenoid plunger and the solenoid mounting surface, distance X. See Detail B on the illustrations.4. Turn the key switch off to remove the electrical power from the solenoids.5. Move the lift control lever to the RAISE detent position. Move the tilt control lever to the TILT BACK detent position. The roller should be in the detent, see Detail A on the illustrations.6. Distance Y is the distance from the top of the extended solenoid plunger to the solenoid mounting surface. Measure distance with all slack removed from the linkage. It must equal distance X + 13 mm (.5"). If not, loosen the locknut on the solenoid plunger rod and turn the solenoid plunger on the threaded rod until distance Y is correct.7. Turn the key switch on to energize the kickout solenoids. The solenoid plungers must be pulled in and the lift and tilt control levers must release from the detent position.8. Repeat Steps 4, 5 and 7 several times to check the operation of the kickout solenoids.9. Repeat Steps 4, 5 and 6 to check dimension Y.10. Tighten the locknut on the solenoid plunger rod.
