Hydraulic Tank

CLEAN Tank can be cleaned with or without steam. If steam is available use a hose with a minimum diameter of 19 mm (0.75 in.). Control the pressure of the steam by a valve installed at the nozzle of the hose. If a metal nozzle is used, it must be made of a material that does not make sparks. Make an electrical connection between the nozzle and the tank. Connect a ground wire to the tank to prevent static electricity. 1. Remove all the parts from the tank. Install the drain plug.

WARNING When cleaning the tank, do not use solutions that make dangerous gases at normal temperatures or when heated. Wear eye and face protection. Protect the body from burns. If the tank is cleaned inside a building, make sure there is enough ventilation.

CAUTION 1. RETURN PIPE 2. HOSE CONNECTION 3. DRAIN PLUG

CAUTION DO NOT to damage the studs during removal of the hydraulic tank from the frame. 23. Lift the hydraulic tank from the studs and move the hydraulic tank away from the frame.

INSPECT WARNING Do not use tools that can make sparks, heat, or static electricity. The vapors in the tank can cause an explosion. Make a visual inspection of all sides of the tank. Inspect the welds for cracks and leakage. Check for wet areas, accumulation of dirt, and loose or missing paint caused by leakage. Areas of the tank that are not easily seen can be checked with an inspection mirror and a light that is approved for locations with flammable vapors.

Disposal of lubricants, fluids, and chemicals must meet local environmental regulations. 2. Fill the tank with a cleaning solution. Proceed as follows: • If steam is available, fill the tank 1/4 full with a solution of water and sodium bicarbonate or sodium carbonate. Mix 0.5 kg (1 lb) per 4 liter (1 gal). • If the tank cannot be cleaned with steam, mix a solution of water and trisodium phosphate or cleaning compound with an alkaline base. Follow the instructions given by the manufacturer.

WARNING Compressed air can move particles so that they cause injury to the user or to other personnel. Make sure that the path of the compressed air is away from all personnel. Wear protective goggles or a face shield to prevent injury to the eyes. 3. Mix the solution in the tank using air pressure. Make sure all the surfaces on the inside of the tank are flushed with the solution. 4. Drain the tank. 5. If steam is available, put steam into the tank until the tank does not have odors and the metal is hot. Steam vapors must come from all the openings.

7


Hydraulic Tank 6. Flush the inside of the tank with boiling water. Make sure all the loose material and cleaning compound is removed from the inside of the tank. 7. Make an inspection of the inside of the tank. If it is not clean, repeat Step 5 and Step 6 and make another inspection. When making inspections, use a light that is approved for locations with flammable vapors. 8. Check the tank for flammable vapors. Put plugs in all the openings in the tank. Wait 15 minutes, then remove the inlet and outlet plugs. Test a sample of the vapor with a special indicator for gas vapors. If the amount of flammable vapors is above the lower flammable limit, repeat the cleaning procedures.

ADDITIONAL PREPARATIONS FOR REPAIR If nitrogen gas or carbon dioxide gas is available, prepare the cleaned tank for welding using these gases. See the manual Safe Practices for Welding and Cutting Containers That Have Held Combustibles by the American Welding Society, F4.1-1999. If these gases are not available, fill the tank with water to just below the point where the work will be done. Make sure the space above the level of the water has a vent.

REPAIR Small Leaks Use the following procedure to repair small leaks: 1. Use steam to clean the area around the leak. Remove all paint and dirt around the leak. 2. Apply LoctiteÂŽ 290 to the leak. Follow the instructions of the manufacturer.

100 YRM 1349

CAUTION Welding on the truck may cause damage to the engine, transmission, and/or hydraulic electronic control units if proper precautions are not taken. Disconnect the negative battery terminal from the battery. Disconnect all ECM’s. If welding must be done in a close proximity of an ECM, that ECM must be removed. When welding to the chassis, attach the ground cable as close the weld as possible. 1. Use the procedure described under Clean to prepare the tank for repairs. 2. Contact your dealer for Yale lift trucks for welding instructions. 3. Use acceptable welding practices to repair the tank. See the American National Standard Safety in Welding and Cutting, AWS Z 49.1 - 1999.

Preparations for use After Repair 1. Add more water to the tank so that the water goes above the point of where the work was done. Check to see if there are any leaks coming from tank. 2. If there are no leaks coming from the tank, remove all the water from the tank.

INSTALL NOTE: When installing the hydraulic system oil filter, it is important to grease the O-ring before installation. 1. Place the hydraulic tank on lifting equipment and support with blocks of at least 50 mm (2.00 in.) thick to cover the height of the bracket at the bottom of the hydraulic tank. 2.
