Truck spill prevention measures are as follows:
1, well disposal of all pads. Such as the oil pan or valve covers, the contact area, which is difficult compaction, likely to cause oil spills. Crankshaft oil seal oil spills, oil will penetrate the clutch, both cost oil contamination will make the clutch slipping and burning.
2, according to the repair specifications tighten the nut. Pressure is not too loose will be tight liner permeability; too tight around the metal will screw threaded screw protruding or sliding caused oil spills. Oil pan (tank shell) If you do not tighten the drain plug loose or back off, likely to cause huge loss of oil, and subsequent "Burnt axle" accident.
3, the timely replacement of failed oil seal. Seal to improper installation, journal and seal edge misalignment, deflection and vulnerable to rejection oil; some long-term use, due to aging and loss of elasticity of rubber, seal lip damage from cracking or failure of tight spring, seal oil will lose the role of the standard should be qualified to repair or replace parts.
4, a serious and timely replacement of worn parts. For example, the cylinder liner, piston, piston ring wear to a certain extent, make the combustion chamber pressure gas into the crankcase.
5, repaired for the main bearings. When the main bearing and the journal the gap is too large, front and rear crankshaft oil seal knock-on effects due to loss of seal, causing leakage of oil from the crank head, or permeability within the clutch, thus contaminating the friction plate lead to slip, work lapse.
6, to avoid rejection of the oil hub. When the wheel bearings (wheel hub bearing) and the cavity too much grease, or oil seal wheel assembly inappropriate, poor quality, often caused by aging failure and brake wheel and axle nut loose temperature is too high, the wheel will cause rejection of the oil . Cavity lubrication should be used (ie, amount of lubrication), and clear the vent, the rational use of the brake, strict selection of quality parts, according to process specifications for assembly and adjustment.
7, to avoid the one-way valve, vent blocked. After this type of valve hole lead box blocked shell temperature, pressure, piston resistance, fuel, oil and gas filled the entire space, increasing oil consumption and replacement cycles. As the pressure difference between inside and outside the tank shell effect, often causing weakness of oil seal. Should be regularly checked, clear, clean, in order to maintain a one-way valve, flow through the valve.
8, to properly resolve all kinds of pipe joints seals. Pipe connection nut often removable, easy to buckle and break due to slip loose wire, so that the two joint bell less accurate, due to the cone centerline does not coincide bad, but not consistent due to the different taper, etc., resulting infiltration the oil. Ground pipe joints should be sealed with the bell or wallet in the two thin copper cone, tighten, compaction nut to ensure sealing.
