What to do if Komatsu 730E controller does not operate?
If the Komatsu Trucks controller does not operate, ensure that there is electric power to the pump controller. The Power LED must light, and the Pump On LED must light when manual lubrication is pressed.
What to do if Komatsu Trucks injector indicator stem does not operate?
If the injector indicator stem on your Komatsu Trucks does not operate, it could be due to a malfunctioning injector, typically indicated by the pump building pressure and then venting; in this case, replace the individual injector assembly. Alternatively, if all injectors are inoperative, the pump build-up may not be sufficient to cycle the injectors, requiring service and/or replacement of the pump assembly.
What to do if the Komatsu Trucks pump will not prime?
If the Komatsu Trucks pump will not prime, it may be due to a low lubricant supply. Check for dirt in the reservoir, a clogged pump inlet, or a clogged filter.
How to fix Komatsu 730E bearing points excessively lubricated?
To fix excessively lubricated bearing points on your Komatsu Trucks, ensure that the controller memory mode is switched on. If it is off, switch it on. Additionally, check the injector output adjustment setting and readjust it to a lower setting if it is too high.
Why is my Komatsu Trucks pump will not build pressure?
If your Komatsu Trucks pump will not build pressure, there are several potential causes. The first is air trapped in the lubricant supply line; prime the system to remove any trapped air. Another cause could be a leak in the lubricant supply line, so check the lines and connections to repair any leakage. Additionally, the vent valve may be leaking, requiring cleaning or replacement. Lastly, the pump may be worn or scored, necessitating repair or replacement of the pump assembly.
What to do if Komatsu 730E Trucks bearing points are not sufficiently lubricated?
If the bearing points on your Komatsu Trucks are not sufficiently lubricated, it could be due to several reasons. First, check the timer/controller cycle time setting and ensure it is not too low; if it is, set a longer cycle time or re-evaluate the lubrication requirements. Also, verify that the injector output adjustment setting is not too low, and readjust it if necessary. If the cycle time doesn't deliver lubricant often enough, set a shorter cycle time or re-evaluate lubrication needs. Lastly, the system might be too large for the pump output, so calculate the system requirements.
Why is my Komatsu Trucks pressure gauge not registering pressure?
If the pressure gauge on your Komatsu Trucks is not registering pressure, first check the hydraulic hose from the steering system to ensure there is system pressure to the pump motor. Also, verify that there is a 24VDC signal at the pump solenoid. If not, identify the problem in the 24VDC electric system. It's also possible that the pressure reducing valve is set too low, and in that case, the relay should be replaced.
