Follow the procedure below to inspect it and be sure to use it only under safe conditions. If any problems are found during inspections, repair or replace the part immediately. A change inspection must be performed when parts are replaced. 1. The sheave groove must be smooth to avoid damaging the wire rope. Use a grinder to smooth and correct any sharp corners. 2. Check whether or not the sheaves turn lightly. If a sheave turns heavily, the wire rope will slide against the sheave, and the rope may be damaged. If a sheave turns heavily, inspect the sheave bearings, and lubricate or replace them if necessary. 3. Check that the sheave split pins and installation bolts are securely installed. 4. Check that the hook nuts are securely installed. If necessary, tighten them further or take steps to prevent their rotation. 7. Perform a magnetic flaw detection test at least once a year to check for cracks or other flaws in the hook. Replace the hook immediately if any cracks are found. 8. As shown in the figure, punch marks are stamped on each hook. Replace the hook when the deformation of the dimension (a) between these marks has increased by 5%. 9.

29 Y-4 Y-4 Air Bleeding Procedure Y-4 Air Bleeding Procedure 1. Hydraulic pump [NOTICE] Be sure that the following conditions are met before starting the engine. PTO : OFF Air conditioner : OFF Oil cooler : OFF The following is also possible: After performing step 3 under 1.1, perform step 2 under 1.2. Start the engine, then turn ON the PTO, and run-in the pump for 10 minutes. 1.2 Main pump 1. Fill the oil tank with hydraulic oil. (If the suction section was disassembled for repair or other reasons, bleed air from the air-bleed plug on the suction side, as described above.) 2. Bleed the pump case. Remove the drain plug or the drain hose of the pump. Pour the hydraulic oil into this drain port until the oil overflows, then tighten the plug. 1.1 Steering and winch brake pilot pressure pump (double gear pump) 1. Fill the oil tank with hydraulic oil. 2. With the engine stopped, loosen the air-bleed plug (G1/4) on the suction flange of the pump. After bleeding air from the suction side, tighten the plug again. 3. Start the engine (with air conditioner, oil cooler and PTO OFF) and run it at idle (approximately 700 min -1 ) for 1 minute to bleed the circuit. 3. Start the engine with PTO ON, and run-in the pump at idle for 5 minutes. 4. Start the engine, and run-in the pump for 10 minutes at idle. 20 WY E

30 Y-4 Y-4 Air Bleeding Procedure 1.3 Main pump (when the tank pressurization tool is used) [NOTICE] Adjust the pressure setting of the tank pressurization tool to 15 kpa {0.15 kgf/cm²} (2.2 psi). During work, check the pressure gauge so that the pressure is within 15 kpa {0.15 kgf/cm²} (2.2 psi). Never actuate hydraulic cylinders with the tank pressurization tool attached. 1. After replacing the hydraulic pump or the hydraulic oil, check that the oil level is at the specified level. 9. After checking that there are no abnormalities, remove the tank pressurization tool on the top of the hydraulic oil tank and attach the air breather to the original position. 10. Now the bleeding is complete. If the hydraulic pump has been replaced, run-in the pump. 1.4 Tank pressurization tool 1. Valve assy (A)(Part number: ) 2. Remove the air breather on the top of the hydraulic oil tank and attach the tank pressurization tool. 3. Slowly loosen the air-bleed plug on the top of the main pump and let the oil with bubbles flow out. 1.5 Other (cylinder) 1. When bleeding cylinders thereafter, make the engine speed medium (1000 min -1 or less). 4. After making sure that flowing oil contains no more bubbles, tighten the air-bleed plug while the hydraulic oil is flowing out. 2. If the oil temperature is to be increased for the purpose of pressure adjustment, do so when there are no bubbles in the oil as a result of air bleeding. 5. While the tank is pressurized, turn ON the PTO switch and start the engine. After idling the engine for 5 seconds, turn ON and OFF the PTO switch repeatedly and quickly and check for any abnormal noise. 6. If any abnormality is found, bleed the hydraulic pump again. 7. If there are no abnormal noise, turn ON the PTO switch and idle the engine for 5 minutes with no load. 8. During idling, check for any abnormal noise or heat of the hydraulic pump and oil leaks from the whole system WY E

31 Y-4 Y-4 Air Bleeding Procedure 2. Winch brake [NOTICE] To avoid damage to the friction plates of the winch brakes, bleed the winch brakes following the procedures below. 1. When assembling piping, plug the piping between the hoist-down port of each main and auxiliary winch motor and the corresponding hydraulic pilot control valve (main). (For plugging, attach plugs to the pipe end closer to the hoist-down port of each motor and the one closer to the corresponding hydraulic pilot control valve port.) [NOTICE] After assembly, do not perform hoisting operation. Hereafter, hoist-up operation by the main and auxiliary winches is prohibited until bleeding of the winch brakes is completed. 2. Perform hoist-down operation of each main and auxiliary winch using the corresponding air-bleed plug of the winch brake. Engine: idling Corresponding control lever moved fully to the hoist-down side (You need not move the winch lever to and fro.) When no more bubbles come out of the plug, bleeding is completed. 3. After bleeding of the winch brakes is completed, remove the plugs from the piping and connection sections, and reassemble the piping. 22 WY E

32 Y-4 Y-4 Air Bleeding Procedure 3. Service brake [NOTICE] The vehicle has two boosters; one for the front wheel brakes and the other for the rear wheel brakes. Take care of spattering the brake fluid and the fluid level in the fluid reservoir while bleeding. 1. With the sufficient compressed air in the air reservoir, depress the brake pedal and loosen the air-bleed plug on the booster to bleed the circuit. 2. Then tighten the air-bleed plug before releasing the brake pedal. 4. Hydraulic motor assy 4.1 Swing motor [NOTICE] Do not apply any load to the motor before completing air bleeding. Bleed the swing motor by following either (1), (2) or (3). (1) Pour the hydraulic oil through the drain port into the casing until the oil flows out. 3. Repeat the above steps until the flowing brake fluid contains no air bubbles. After the air bubbles go out, tighten the air-bleed plug while letting the fluid flow out. [NOTICE] The vehicle has two air-bleed plugs for the front axle and two for the rear axle. 4. Bleed the wheel cylinders in the calipers of the axles in the steps same as above. (2) Perform the right or left swing operation slowly for approx. one minute. (3) Set the swing brake switch to ON.
