If the walking tractor is idle for a long time, there will be a series of problems and failures. In order to avoid failures when it is used again, pay attention to the maintenance measures.
b. Pad parts. Pad the tractor with wooden piers or masonry to reduce the load on the tires; if the pads are not supported, the tires must be inflated by 10% to 20%, and they must be checked frequently to ensure that they are always inflated and must not be deflated.
c. Thoroughly wash. Remove the dirt and oil on the surface of the tractor, check, adjust and tighten all parts and screws comprehensively to avoid loosening and falling off.
d. Drain oil and water. After the tractor is stopped, all the cooling water, diesel oil, engine oil, etc. in the engine should be drained.
e. Maintenance parts. Take an appropriate amount of dehydrated engine oil (heat the engine oil to about 130°C) and pour it into the intake pipe, turn the crankshaft to make the engine oil adhere to the piston, piston rod, cylinder liner and valve. And shake the piston to the compression top dead center, so as to prevent the valve spring, push rod and other parts from being compressed for a long time and lose their performance.
f. Remove the fuel injector. After cleaning the injector, put it into clean diesel oil, loosen the adjusting screw, and block the hole chamber of the injector with a wooden plug.
g. Fill the axle box with oil. Take 1kg of dehydrating machine oil, pour it into the crankcase, and then shake the crankshaft several times, so that the lubrication system is completely filled with dehydrating machine oil.
h. Parts washing oil. Coat all the fastening parts such as the rocker arm, high-pressure oil pipe, oil sprayer, bolts and nuts with dehydrating machine oil to prevent rust.
i. Lubricate well. According to the overall lubrication requirements of the walking tractor, select lubricating oil that meets the standards for sufficient lubrication.
j. Bandage dustproof. Bind the engine's air filter, exhaust duct, water tank port, fuel tank port and other places that are easy to enter dirt and dust with plastic cloth or oil paper to prevent sundries and dust from entering.
k.Battery. First of all, keep the vent hole of the battery unblocked, because hydrogen and oxygen will be generated during the use of general-purpose batteries, and if the vent hole is blocked, the battery may rupture. Secondly, pay attention to the liquid level of the battery, the normal liquid level should be 10-15mm higher than the plate. Unused batteries should be stored in a cool and ventilated place.
(a) Maintenance parts: Pour an appropriate amount of dehydrated engine oil into the intake pipe, turn the crankshaft, and make the engine oil adhere to the piston, piston rod, cylinder liner and valve.
(b) Oiling of parts: fastening parts such as rocking walls, high-pressure oil pipes, fuel injectors, bolts and nuts should be coated with dehydrating machine oil to prevent rust.
(c) Dust-proof binding: Use plastic cloth or oil paper to bind the engine air filter, exhaust duct, water tank port, fuel tank port, etc. that are easy to enter the dust, so as to prevent debris and dust from entering.
