(1) With the clearance A between the lining and drum set approximately to specification, pull the cable with spring with a finger as shown. The lever should turn the adjusting screw wheel by one notch and, when the cable is released, return to the original position.

(2) If the lever fails, or is slow, to turn the adjusting screw wheel, check the position of the lever relative to the toothed wheel. The lever’s actuating tip should touch the toothed wheel at approximately 7 to 9 mm (0.28 to 0.35 in.) below the centerline of the screw. If the lever contact is out of the range, the lever will not correctly engage with the toothed wheel, therefore failing or slow to turn the wheel.

(3) If the automatic adjuster fails to operate correctly, take the following actions.

(a) Ensure that the adjusting spring is correctly hooked to the primary shoe.

(d) Replace the adjusting screw.

Warning: This inspection requires trained personnel with PPE!

Measure the resistance value of the relay coil between terminal 1 and terminal 2

Is the measured resistance value within the standard range?

Measure the insulation resistance value between terminal 3 and terminal 4

Is the measured insulation resistance value more than the value listed in the table?

Apply a voltage of 12 V ON and OFF across terminal 1 and terminal 2

Does the relay activate to cause continuity between terminal 3 and terminal 4?

Hydraulic Pump Inspection and Repair

(1) Check the gear teeth for wear, chipping or other defects.

(2) Check the side faces of the gears for wear or damage.

(3) Check the shafts for wear or damage.

Check these parts for wear or damage.

1. Second cylinder for simplex mast and triplex mast Inspection after disassembly

The following parts should be periodically changed as noted below.

These parts are made of materials which will deteriorate overtime. Further, it is difficult to determine visually whether or not they are still in good condition. Changing at proper intervals will reduce the risk of injury to the operator and damage to the truck.

4000 service hours or 2 years, whichever comes first:

• Rubber parts of power cylinder

• Hydraulic hoses of steering system

4000 to 8000 service hours or 2 to 4 years, whichever comes first:
