Adjust. Move the chain tightener sprocket (6, fig. 3-36) against the chain until chain is free of slack, then tighten
the nut (12, fig. 3-36) on the chain tightener. The tension is correct when chain can be depressed about 1/2 inch at a
point midway between drive sprockets.
3-59. CHEMICAL SLURRY FEEDER SLIP CLUTCH ASSEMBLY.
The slip clutch assembly (2, fig. 3-36) is located on the drive end of the slurry feeder agitator shaft. It protects the
drive components and slurry feeder from damage if an overload is applied to the agitator shaft. Adjustment of the slip
clutch is made as follows:
Remove the chain guard (para 3-56). Pull loop end of the lockring (13, fig. 3-36) out of hole in the adjusting nut
(12) and place a block under it to keep it out.
Turn adjusting nut clockwise to increase torque. Gradually increase or decrease torque until the correct
operation is obtained.
The clutch must be just tight enough to prevent slipping during normal operation but loose enough to
slip under abnormal load.
After the clutch has been adjusted, lock the adjusting nut. Turn the adjusting nut so the loop end of the lockring
extends through a hole and into a tooth space in the drive hub.
Install the chain guard.
3-60. ERDLATOR AGITATOR DRIVE SHAFT, FLEXIBLE COUPLING, AND PILLOW BLOCK BEARINGS.
General. The erdlator agitator driveshaft assembly (5, fig. 3-37) is located on top of the erdlator tank and bridge
rails, between the drive motor and speed reducer. It transmits power from the erdlator erdlator drive motor to the speed
reducer to drive the erdlator agitator.
Drycleaning solvent, P-D-680, used to clean parts is potentially dangerous to personnel and property.
Wear chemical resistant gloves when using solvents, and avoid repeated or prolonged skin contact.
Do not use near open flame or excessive heat. Flash point of solvent is 100 degrees F to 138
degrees F (38 degrees C to 59 degrees C).
Cleaning. Clean all parts with drycleaning solvent.
Inspect shaft for misalignment.
