Routine maintenance, class after work. 2, the level of technical maintenance, accumulated 100 hours of work, a group working system is equivalent to two weeks. 3, two technical maintenance, accumulated 500 hours, the equivalent of a quarter of a group working system. First, a routine maintenance, cleaning the truck dirt, mud and dirt Egypt, key positions are: YTO forklift frame and door frame slide, generator and starter, battery electrodes fork columns, tanks, air filter. 2, check all parts of fastening, focusing on: Fork supporting, lifting chain tensioning screw, wheel bolts, wheel fixed pin, brakes, steering screws. 3, check the foot brake, steering reliability, flexibility. 4. Check for leaks, focusing on: all fittings, diesel tank, sump, pump the brake, lift cylinders, tilt cylinders, tanks, pumps, engine oil pan, torque converter, transmission, drive axle, the main reduction , hydraulic steering, steering cylinder. 5, put the oil filter to precipitate.
Second, a technical maintenance in accordance with the "routine maintenance" project, and add the following work. 1, check the cylinder pressure or vacuum. 2. Check and adjust valve clearance. 3, check the thermostat is working properly. 4. Check the multi-valve, lift cylinders, tilt cylinders, steering gear if the fuel tank and pump is working properly. 5. Check the transmission's shift work properly. 6. Check and adjust the hand, foot brake, brake pads and brake drum clearance. 7, the replacement of the oil sump, check the crankcase ventilation takeover is intact, clean oil filter and fuel filter element.
8. Check the generator and starter motor is firmly installed, and lugs are clean firm, check brushes and commutator for wear. 9. Check the fan belt tightness. 10. Check the wheel is firmly installed, meets the requirement if the tire pressure, and clear debris embedded in the tread. 11, due to maintenance work and dismantled parts, when re-assembled to conduct the truck road test. (1) braking performance under varying degrees, there should be no deviation, hunting. On the steep slopes, after the hand brake tension, can reliably stop. (2) to listen to the engine under acceleration, deceleration, reload or load operation, etc., there is no unusual sounds. (3) road test some mileage, check brakes, transmission, front axle, gear pumps at the presence of overheating. (4) YTO rough terrain forklift lifting speed is normal, with or without shaking. 12, check the diesel tank of fuel filter has blocked imports of damage, and clean or replace the filter.
Three, two technical maintenance and except a technical maintenance projects, and add the following: 1, cleaning the tank, filters and piping, and check for corrosion, cracking collision case, after cleaning may not be used with fiber the yarn, cloth wipe. 2, cleaning torque converter, transmission, inspect parts for wear, replace with new oil. 3, check the drive shaft bearing, depending on the need to exchange universal joint cross-axis direction. 4. Check the drive axle fastening ministries and whether leakage, and clear pores. Dismantling the main gear, differential, wheel reducer, adjust the bearing axial clearance, add or replace oil. 5, dismantling, adjustment and lubrication of the front and rear wheels, axle were transposed. 6, cleaning brakes, adjust the clearance between the brake drum and brake shoe lining between. 7, cleaning liberal amount of rotation steering, check the steering wheel. 8, disassembly and cleaning gear pumps, pay attention to check the wear of the gear housing and bearing 9, demolition multi-way valve, the stem and the valve clearance check, do not open the safety valve, if not necessary. 10, check for damage and cracks knuckles, steering axle kingpin with the situation with the knuckle, dismantling the vertical and horizontal rod and steering arm joints wear. 11, removing a tire on the rim rust paint, check the tires and tubes and flaps, transposition accordance with the provisions inflated. 12. Check the connections are tight hand brake parts, adjusting the hand brake lever and foot brake pedal stroke work. 13. Check the battery electro-hydraulic proportion, as inconsistent with the requirements, the charge must be removed. 14, clean water tank and oil cooler. 15, check the shelves, frame without deformation, washable wheel, each accessory is reliable fixed, restocking weld if necessary. 16, dismantling the lifting cylinders, tilt cylinders and steering cylinder, replace worn seals. 17, check the instrument sensors, fuses and various switches, make adjustments if necessary. Fourth, the whole car or truck lubrication new truck stops working after a long time, within two weeks at the start of use, should be lubricated bearings for when lubrication, Chen should take advantage of new oil will all the oil out, and lubricate twice above, and should pay attention to the following points: 1, should be removed before lubricating oil cap, oil drain plug and nozzle above the dirt, dirt to avoid falling into the house. 2, with the grease gun lubricant injection pressure, injection pressure to be part of the components of the combination of the extrusion lubricant so far. 3, should be replaced in the summer or winter seasonal lubricant (oil, etc.).
