Komatsu Forklift Truck FD15C-20

PROCEDURE FOR ADJUSTMENT OF BRAKE SHOE CLEARANCE

1. Release the parking brake while floating the wheels up above the ground.

3. Turn the gear (1) in the direction (A) or toward the brake shoes repeatedly with a screwdriver until the brake shoes should touch the brake drum. Turning of every notch makes sound of clicks.

IMPORTANT: Turn the wheels by hands to feel braking a little bit.

4. Prepare two screwdrivers. The first screwdriver should be used for mildly pushing the lever (2) and have it miss each gear notch. Be careful not to push strongly. The second one should be used for turning the gear (1) toward the direction (B) counting by twenty-one (21) notches while the fist one is still on duty. It counts 30 notches for one turning of the gear.

IMPORTANT: Since no clicks are made available here, count the number of notches watching through the hole of the rubber cap (3) for carrying out the adjustment.

6. Turn the wheels by hands and check to make sure that there is no brake dragging.

2. Fix the pressure plate with the pressure plate mounting bolt.

3. Slide the snap ring (1) and remove the pin (2).

4. Push the shaft toward the transmission.

5. Remove the pressure plate mounting bolt (3) and slide the pressure plate. Then, remove the clutch disc.

Be careful not to damage the spring when sliding the pressure plate.;

1) Remove the spark plug with the special plug wrench.

2) Clean the carbon up stuck on the plug head and the surroundings.

3) Measure the plug gap A as shown on the illustration on the right with the plug gap gauge. Plug gap A: 0.7 to 0.8 mm;

• Before starting bleeding air, adjust the brake shoe clearance to the specified 0.40 to 0.56 mm (diameter of the space).

• From time to time, refill the brake fluid to prevent the brake fluid in the reserve tank from empty for carrying out air bleeding. You should carry out the inspection again just from the beginning because air could be mixed in once the tank becomes empty.

1. Remove the cap from the air bleed plug (1) of the brake wheel cylinder. Install one end of a plastic hose for air bleeding to the plug and put the other end of the hose in a container of the brake fluid.

The color of the plastic hose should be transparent as much as possible.

2. If inspector is only one, connect a string or a wire to the upper arm of brake pedal (2) and let the other end of string or wire loose free in approximately 300 mm through the space between the frame (3) and the dashboard (4).

3. Slowly pull out the string or the wire connected with the brake pedal (2) arm from the front of the forklift so as to compress the air inside the brake piping and hold it as is.

If inspector is more than two, one inspector should press the brake pedal.

4. Loosen the air bleed plug (1) of the brake wheel cylinder approximately 3/4 turns to the left and depress the brake pedal to bleed the air in the piping along with the brake fluid. Then, tighten the bleed plug (1) while bleeding the brake fluid.

1. Remove the oil filler plug and drain the oil through the drain plug.

2. After draining, tighten the drain plug and refill the oil as specified.

3. Check the oil level after refilling.

IMPORTANT: Be sure to always use the Komatsu genuine oil "FG090" for the gear oil.

The same oil is being used at the differential case and the transmission case for the clutch model, while the specifications of the oil being used at those devices differs for the TORQFLOW type.

Therefore, the TORQFLOW type requires inspection and replacement of the TORQFLOW transmission case in addition to those of the differential case.;
