Keluo company have lots of Deutz engines for sale, we are excellent quality, perfect service as the core, to provide reliable power support for customers around the world, in the process of customer use and maintenance of Deutz engine, we found some common misconceptions, hereby combing, hope to help users more scientific engine maintenance.
1. Misconceptions about valve cover bolt tightening
Many people think that when assembling the valve cover, the tighter the bolts are tightened, the better. However, for DEUTZ diesel engines, the valve cover is an aluminum shell with a specific tightening torque of only 9 NM. In the actual assembly process, if the force is too much, the aluminum shell will be severely deformed due to the excessive pressure. There was once a maintenance staff, with experience, over-tightening the bolts, thought it could be better sealed, the results of the engine soon after the start, the valve cover around the beginning of a large number of oil leaks. This is because the deformation of the aluminum shell destroys the original sealing structure, making the sealing effect greatly reduced, but the shell is more likely to leak oil. Therefore, when assembling the valve cover, be sure to operate in strict accordance with the specified torque, do not be too tight dead valve cover.
2.Misconceptions about valve cover gasket oil leakage treatment
When oil leakage occurs at the valve cover, some people will try to put oil on the valve cover gasket in the hope of reducing the oil leakage. However, this does not work. There have been cases where users have noticed oil seepage from the valve cover and applied oil to the pad themselves, but the oil seepage problem persisted and even worsened over time. The correct solution is to replace the new gasket in time, if there is no new gasket, you can also add a piece of gasket on the old gasket to enhance the sealing effect. By replacing or stacking the mat, can effectively fill the mat due to aging, deformation and other causes of the sealing gap, so as to solve the oil leakage problem.
3. Monoblock pump oil judgment misunderstanding
After disassembling the monobloc pump on the high-pressure oil pipe, if found from the monobloc pump out of the oil, many people will immediately determine that the monobloc pump has been damaged. However, for the present DEUTZ1013E/1013ECP diesel engine, its low pressure oil circuit is all 5bar system, and there is no check valve at the outlet of the monobloc pump of the system (unlike the 3bar system which has a check valve, and is characterized by the length of the pump body which is longer than that of the 5bar system). Therefore, when the high-pressure fuel line is removed, due to system pressure changes, etc., it is likely that oil will flow out of the monobloc pump outlet, which does not necessarily mean that the monobloc pump is damaged. For example, in an engine maintenance process, maintenance personnel to see the monobloc pump after removing the high-pressure oil tube bubbling oil, almost misjudged the replacement of expensive monobloc pumps, in time to understand the characteristics of the oil circuit of the model, to avoid unnecessary losses.
4. Monomer pump gasket replacement misunderstanding
Some people think that a cylinder of the diesel engine monobloc pump replacement, monobloc pump on the gasket must be replaced. In fact, in the replacement of the monomer pump, if the old and new monomer pump “A” value difference in the “5” or less, the gasket does not need to be replaced. This is because when the “A” value difference is small, the original gasket fit is still good, continue to use and will not affect the normal performance of the monoblock pump. For example, in a repair, maintenance personnel to follow this principle, did not blindly replace the gasket, not only saves maintenance costs, but also shorten the repair time, and the engine runs stably, without any abnormalities.
5. Monobloc pump after the installation of the inspection of misconceptions
Others feel that after installing the monobloc pump, no need to do any check to start the engine for work. But the correct approach is, after installing the monobloc pump, to be observed from the parking solenoid valve (at this time toggle the parking handle) whether the rack is flexible movement. If not flexible movement, that the monobloc pump is not installed. There have been maintenance personnel did not carry out this check on the start of the engine, the results of the engine appeared to be violent shaking, can not run normally, after checking the monobloc pump is improperly installed to cause the rack movement is blocked. Only to ensure that the rack can be flexible movement, in order to ensure that the monobloc pump normal work, and then ensure that the engine smooth start and stable operation.
The company reminds the majority of users, correctly recognize the maintenance of these wrong ideas, strictly in accordance with the scientific method of operation, in order to let the Deutz engine always maintain a good state of operation, for your production and life continue to provide reliable power.
