The throttle is 10 vehicles have been working for 100100 hours no repair engine. Now talk about the problem of holding back the car. In the car work, reporting will drop point by drop, resulting in fire fighting. When driving uphill, hold back to extinguish the fire. The work is in small hard tired things will have to fire. The parts of the 2 hydraulic pumps have been cleaned. But it still does not work, the car reported at work when the gap is great. Very unstable. Does the problem relate to high pressure pumps or to hydraulic pumps? Is it caused by power mismatch, or what's wrong?. StopThe car is Hitachi 330. Direct fired. OK, on the downhill, the car will go off. Sometimes the 2 sides stop together and get stuck. Just shake it and make it work.
This is the problem of the oil pump, you still did not find the right person to repair, but it is a bit blocked, and my family Daewoo 220 is this situation, a few hundred pieces on it, the landlord quickly go to repair it
Your hydraulic pump has been cleaned, but is it appropriate to adjust the pressure? What else is the problem with the hydraulic pump?. Sometimes these conditions can occur with too much pressure regulation. If the pressure is normal or lower, it should not be a hydraulic pump. You can now find a school oil pump master to show you, ah, as long as the master is generally, you can certainly be an oil pump problem. Do you have a lot of exhaust under your engine, and do you have engine oil? These are the criteria for determining whether or not your engine is having problems. If the diesel pump, with the hydraulic pump is no problem, it is only the demolition of the engine overhaul. Exception, you walk running, the reason may be the hydraulic pump on both sides of the uneven pressure regulation, or side of the walking pump wear a little bit larger.
It is possible that the hydraulic pump is seriously worn out. It needs to replace the pump bladder with the valve plate and the swashplate. The problem of deviation is that the running overflow valve or the balance valve is not working
Hold back the car, that is, the car was stuffy, accelerated weakness, basically due to:1 、 the air inlet is not clear and the air filter core is blocked2, the exhaust is not smooth3, the fuel timing is wrong (premature)Basically for these reasons:My car excavator is simple: to dig in the car, with the normal work of the engine, when the power is greater than the resistance, the engine speed will rise, the car ran faster and faster; when the resistance is greater than the power, there will be the engine speed down, smoke or even flameout. The same thing applies to excavators. Only by digging machine is the engine to drive the hydraulic system to work.
Since your engine has been running a little bit longer, check the oil pump first. If it doesn't solve the problem, you're going to fix the engine! 2, your chain is badly worn
