 XT3514k telescopic handler  Reasons and solutions for loader engine failure to start

Fuel issue

The first thing to check is the fuel quality. If the fuel quality is poor, or if low-quality, water containing, or expired fuel is used, it will cause the loader to fail to ignite. To solve this problem, we need to replace the fuel with a new one and ensure that high-quality, clean fuel is used when refueling. The hot car hold up of the excavator may also be caused by the hydraulic system failure. Common reasons include: excessive pump power, worn pump regulators, excessive pressure and flow of pump valve group, worn pump internal components, etc

XCMG XT4018k Chapter II Maintenance Methods

telehandler telescopic handler Maintenance idea:

First, the lgmg h625 mismatch between the power of the excavator hydraulic system (mainly from the main hydraulic pump) and the power of the engine may cause the excavator to hold the vehicle. What is the cause of the mismatch between the power of the excavator hydraulic system and the power of the engine?

1. The STH1440 telehandler power of the excavator hydraulic pump has increased abnormally (the engine power is normal at this time). The reasons for the increase of hydraulic pump power are as follows: 1) The XT3514k telescopic handler  abnormal increase of hydraulic oil temperature leads to the thermal expansion and stagnation of parts of hydraulic pump servo mechanism. 2) The regulator is worn and aged, and the internal leakage seriously interrupts the required power feedback on regulation. 3) The sensor of the hydraulic pump fails (the positive control system is more obvious), and the negative control has little effect. 4) Insufficient first arrival pressure makes the regulator feedback system malfunction. 5) The internal servo mechanism of the hydraulic pump is worn, stuck and leaked. www.haiqinmachinery.com
