Preventing oil leakage measures for Heavy Duty Truck Howo vehicles
1. Attention to the role of the liner. Automobile static parts (such as the joint end face, end caps, shells, cover gasket, flat enamel cover, etc.) between the parts of the liner plays a leakage sealing role. If the material, production quality and installation does not meet the technical specifications, it can not play the role of sealing leakage, and even accidents. Such as the oil pan or valve cover, due to the contact area is not easy to compact, resulting in oil leakage. When disassembling and assembling, pay attention to place properly, check carefully, and assemble according to the specification.

2. All kinds of fastening nuts on the car should be tightened according to the specified torque. Too loose pressure will not tighten the liner leakage; too tight and will make the screw hole around the metal bulge or will be screwed slippery buckle and cause oil leakage. In addition, the oil sump oil drain screw plug if not tightened or back to loose off, easy to cause the loss of oil, and then occurred “burned holding the shaft” machine damage accident.

3. Timely replacement of failed oil seals. A lot of moving parts on the car (such as oil seals, O-rings) will be improperly installed, the journal and oil seal edge is not centered, eccentric and dumping oil. Some oil seals will lose elasticity due to aging of rubber after too long use. Leakage should be renewed in time.

4. Avoid one-way valve, air valve blocked. This causes a rise in temperature inside the case, oil and gas filled with the entire space, the discharge does not go out, so that the pressure inside the case to increase lubricant consumption and shorten the replacement cycle. Engine ventilation system blocked, increasing the piston’s resistance to movement, so that oil consumption increases. Due to the role of the case inside and outside the case of air pressure difference, often cause sealing weak oil leakage.

5. Properly solve the various types of oil pipe joint seal. Vehicle coupling nut is often disassembled, easy to slip wire broken buckle and loose, will cause oil seepage. Replace the coupling nut, use the grinding method to solve its taper sealing, so that the nut pressure to solve the sealing.
