“…PA = 𝑥100% = 95,71% The HD 1500-7 dump truck unit's maintenance performance is calculated in Figure 2 when the standby condition is oil entering through the hydraulic oil inlet (2) and when the auto lube system is running the controller or timer sends a signal to the solenoid valve (3) to open the hydraulic oil line from (2) to the reciprocating pump (7) which passes through the reducing valve (4), oil pressure gauge (5) and flow control valve (6). In addition, there is hydraulic oil that goes to the vent valve (11) through the orifice (12).…”

“…Grease is the lubricant employed in this system because it can enter the spaces between the linkage group components [2]. The automatic lubrication system, also known as the Auto lube system, is utilized in the Dump Truck HD 1500-7 unit's lubrication system [3]. Regular maintenance is required for the Auto lube system, especially regarding the grease level in the grease tank and the pressure of the grease coming from the electric grease pump [4] [5].…”

A lubrication failure resulted in damage to the HD 1500-7 dump truck unit auto lube system, making the system ineffective and leading to lubrication failure on the frame components. Because the damaged HD 1500-7 dump truck unit is inoperable when it occurs, this damage may have an impact on its production. The goal of this study was to ascertain whether maintenance performance on the Dump Truck Brand K type HD 1500-7 unit was impacted by lubrication failure in the auto lube system. Additionally, learn how to assess the Auto lube system on the Dump Truck Brand K type HD 1500-7 and how much electricity the Grease Pump Auto lube system Dump Truck unit Brand K type HD 1500-7 uses. Using a quantitative approach, discover what is causing the HD 1500-7 dump truck unit and the auto lube system to malfunction. The analysis of the Dump Truck HD 1500-7 unit's maintenance performed from February to April 2022 revealed that the average MTBF value is 352.9 hours, the average MTTR value is 5.388 hours, and the average PA value is 96.38%. The oil-powered reciprocating pump produces 537.81 Watts of power. At a grease pressure of 2500 psi, the displacement (grease) pump requires 163.29 Watts from the reciprocating (oil) pump to operate, compared to 58.67 Watts at a grease pressure of 1500 psi. The standard working pressure for the displacement (grease) pump is 2500 psi, whereas the standard working pressure for the reciprocating (oil) pump is 400 psi. The working pressure on the oil and grease does not achieve the standard pressure, an error arises and results in lubrication failure in the frame components, and this might have an impact on the HD 1500-7 unit's maintenance performance

“…Research conducted by (Sugiharjo and Wilarso, 2021) using the fishbone analysis method concluded that a lack of grip on the brakes and insufficient air pressure caused the failure of the braking process. One of the causes of high air consumption is the discovery of brake lining gaps outside the manufacturer's standards.…”

In motor vehicle systems, brakes are one of the important components that have a major role in reducing the risk of accidents on the highway. In the brake system, especially drum brakes, improper component adjustment can cause the brakes not to work optimally. This research was conducted to determine the impact of large variations in the brake lining gap and brake drum temperature on brake efficiency in motorized vehicles. This study uses an experimental method with variations in the adjustment of the size of the brake lining gap and the temperature of the drum brake. The main brake efficiency was tested using a brake tester from these several variations. The variations of the brake lining gap used are 0.3 mm, 1 mm, and 1.7 mm. Meanwhile, the brake drum temperature is set at 30, 90, and 150 degrees Celsius. The result of this research is that the wider the brake lining gap, the smaller the brake efficiency. The greater the temperature on the drum brake also affects the smaller the efficiency of the brake. Meanwhile, the variable brake lining gap and temperature simultaneously (together) affect the level of brake efficiency. The larger gap between the lining and the temperature of the drum brake, the lower the efficiency of the brake obtained.
