The onset of winter, we should be in strict accordance with the relevant technical requirements of the three filters on tractor maintenance cleaning carefully and timely troubleshooting.
According to the local temperature,cast bronze adjust oil specifications, if the minimum temperature at 0 to -5 ℃, the selection of -10 # diesel oil; minimum temperature at -10 to -15 ℃, -20 # diesel oil used.
Meanwhile, in the use of the following questions:
Daily maintenance is the foundation.
First, bronze bushing pay attention to tire pressure. Tire pressure in winter than in summer, about 5% of high requirements to reduce the travel of the rolling resistance.
Second,dry bushing pay attention to warm start. Winter start before around 80 ℃ hot water with increased engine temperature, and open the drain switch, wait about 40 ℃ hot water outflows, then add water to start; temperatures especially cold, released after the shutdown of oil, starting before the increase temperature of 40-50 ℃ and then added to the sump; prohibited the use of ignition, drag, slide slope, Ming roasted cars, car starter, add water, adjusting fuel injection pressure,plain bearing loose starting the wrong way; speed rotation after starting in 15 minutes, until water temperature above 40 ℃ before starting up, the water temperature of 60 ℃ to load operations.
Third,sleeve bushing pay attention to strengthening antifreeze. Winter to heat human tractor to work, such as the installation of insulation curtain, loose fan belt or appropriate tone reduce the fan speed; water heating appliances, anti-skid chains should be prepared to complete, with summer and winter switch engine, the switch to "Winter" position.
Fourth,DU bushing v pay attention to tank water. Tractor did not add antifreeze, the temperature is below 0 ℃ and night to put a stop to make the cooling water; but the water temperature is high until the water temperature drops below 60 ℃ and then turn on the water, bushing or likely to cause the body or the cylinder head and other equipment to produce stress deformation damage; the same time can not drain away from the people, to prevent the release valve by impurities and congestion.
Rational use of the gearbox.
Typically, the tractor's use, transmission from the six well maintained.
First,brass bushing before each shift should be complete separation of the main clutch, and properly control the throttle, so the impact of hanging file generated when the gear. Second, the fast file, the operating lever can not be too much force will damage the fork or the shift axis travel limiting, broken pieces produced the phenomenon of random files. Third, Mould guide plate is to prevent the transmission gear oil seal oil into the clutch room. Therefore, we should regularly check whether the failure of oil seals, such as a serious oil spill should be replaced. Fourth, always check whether the oil split pin at the leaking, if the oil leakage, oil seals should be checked whether the failure. Fifth, gearbox and rear axle the same, plasic bushing all with the same kind of gear oil, lubricating oil from atop the rear axle oil drain plug hole after the injection, fuel plug the holes should be kept on the flow. Rear axle oil level can be measured shell on the right foot oil, the oil dipstick on the surface should be located in the groove between the two. Discharge of oil, it can unscrew the transmission oil drain plug and rear axle oil drain plug, the oil exhausted. Sixth, take the initiative in the power washer shaft surface with gap adjustment to ensure that there is about 0.3 mm gap. Overhaul, such as badly worn and should be replaced.
In use, we should have some common faults to determine, and in a timely manner to ensure the normal use of the exclusion.
As long as transmission used, the internal shaft, bearing wear large, a corresponding surface of the gear wear, gear meshing is not running smoothly, will be issued a cyclical percussion. Planetary reduction gear and shaft of each planetary gear worn, also issued a percussion sound. You should open the gearbox, one by one to identify the reasons, the replacement of damaged parts.
To skip files larger, mainly due to transmission locking mechanism and control mechanism is faulty. Add fork shaft positioning groove wear half-ring, locking the spring force shortage will cause the locking mechanism fails, then should be the replacement of damaged parts. If the fork badly worn or bent, and the lower end of the shift lever ball badly worn will affect the shift schedule, so that location are not allowed to engage the work gear, resulting jump file. Damaged parts should have been corrected and the welding repair or replacement.
Too much force when hanging files, will shift axis travel limiting, bending or breaking, resulting in arbitrary files. At this time, should remove the hydraulic lift cover, back into gear axis travel limiting, films, and check the fork shaft and shift fork is damaged or bent.
Which shall not be blocked outside the hole.
Repair and maintenance tractors, should take the following eight outer holes must not be blocked.
First, plug the injector back to the hole opening after the needle not working, fuel uneven engine instability.
Second, the thermostat of the main valve plug the hole after the body of water flow comprising gas emissions without a net, add less water tank, easily lead to boil. Get in the winter season, hot water tank, easy to freeze the water tank.
Third, after the water pump seal leaking drain hole will plug into the pump bearing shell, so that grease hydration, reduce lubrication, making the pump bearing damage.
Fourth, the air filter cover plug the hole for dust particles in the air after the row could not easily plug the lower filter, suction reduction, power down, or even dust particles into the combustion chamber to speed up the valve, cylinder, piston machine washed wear.
Fifth, after the crankcase vent plug to sump oil thinning and degeneration, reduce lubrication and cause burning oil, so oil consumption to increase.
Sixth, the putter with the putter cover oil pump at the drain plug hole pump oil after the oil pool will be increased, thinning, and spillover.
Seventh, after the battery power plug hole cap emissions can not be discharged within which damage the battery.
Eight holes in the bottom of the clutch housing after the plug once the crankshaft rear oil seal leak, clutch oil deposits, it will lead to clutch slip.
