Analisa Kerusakan Brake System Pada Wheel Loader XGMA 955h

Brake system is a sytem on heavy equipment that functions to slow down and stop the unit moving. Damage suffered by the brake system in the form of loss brakes. This analysis aims to determine the damage, analyze the damage and find out the repair steps. The inspection method is done by checking visually. Next do the disassembly and inspection of brake system components to determine the damage and the main causes of brake loss. The brake system inspection results in component failure which consists of O-ring brake piston and brake piston. The cause of damage to the brake system is because the o-rings of the worn piston and brake piston have rust on the surface, so the brake piston cannot work normally. The repair step is to replace the o-ring of the brake piston and brake piston which is damaged and cannot be repaired, therefore the o-ring of the piston and brake piston is replaced with a new one

Analisa Performa Internal Combustion Engine Satu Silinder Bahan Bakar Bensin Dengan Variasi Air-Fuel Ratio ( 1:15.1 , 1:15.5 , 1:16.2 )

Air Fuel Ratio is the ratio of a mixture of fuel and air that is needed to carry out a combustion process in a combustion engine. The ratio of fuel and air can be expressed in terms of volume or weight of gasoline and air. The fuel must be able to burn completely to produce maximum performance and minimize the level of exhaust emissions caused by the rest of the combustion. This study aims to determine the internal combustion engine performance of single cylinder gasoline, especially on Power, Torque, and Specific Fuel Consumption from the effect of variations in Air Fuel Ratio. The benefits obtained from this research are that it can provide a reference for further research on the effect of gasoline motor performance resulting from variations in AFR, Gaining wider knowledge about the work of a combustion engine, especially in the EFI (Electronic Fuel Injection) system. Quantitative research methods are used to collect data in the form of numbers from experiments and tests to carry out analyzes of the topics discussed. The results of this study are in the form of engine performance data that have been varied and then tested so as to produce conclusions that prove the differences in the results of several variations used in this study, one example is. From the results of calculations that have been obtained, it can be concluded that the smaller the value of Specific Fuel (KBBS) it will be more efficient or fuel efficient used. However, it also affects the performance of the resulting motor will decrease

Analisa Proses Assembly Traktor New Holland Tt3.50 Dan Kegagalan Sistem Hydraulic Pada Three-Point Hitch

The assembly process is sometimes an error-prone job, especially if there are many components that must be assembled, as well as in the assembly process for the new holland TT3.50 tractor. The main driving force of the hydraulic tractor is a diesel engine which converts mechanical energy into hydraulic energy through pump pressure which is then distributed to the hydraulic cylinder to produce energy. The three-point hitch is the most widely used type for installing plows and other agricultural implements, especially on tractor units. The purpose of making this final project is to find out the steps of the assembly process according to standards, assembly to be more efficient and to know the types of failures, causes, and steps to repair damaged components. The research method uses observations on the unit, then the results of the observations become the basis for the analysis of the problem. To find out in more detail, it is necessary to carry out the assembly and disassembly process and to check the components after the assembly and disassembly process is complete, in this case, the New Holland TT3.50 tractor assembly process and the hydraulic oil filter disassembly on the Holland TT3.50 tractor unit. In this case, after the New Holland TT3.50 tractor assembly process was carried out and the hydraulic oil filter disassembly on the New Holland TT3.50 tractor unit. Then the results for the steps in the assembly process for the New Holland TT3.50 tractor include front and rear wheel installation, left and right fender installation, deck floor installation, canopy installation and three-point hitch installation. In order for the assembly to be more efficient, namely by utilizing a jack, and the failure of the hydraulic system in the three-point hitch is caused by a dirty hydraulic oil filter that causes a blockage and the fluid cannot flow perfectly. The fix is to clean the hydraulic oil filter. Efforts to prevent the same problems from happening are by carrying out daily checks and periodic maintenance procedures

Analisa Kerusakan Undercarriage Excavator Komatsu PC 200-8

The undercarriage is the lower part of a crawler tracktor that functions to support the load, direct, and support the unit. Undercarriage has a very important role in excavators where all excavator operations require an undercarriage as a unit stabilizer. Another function of the undercarriage is to support and transmit the load of the excavator unit to the ground, as an excavator propulsion component and to support the unit. The damage that occurs to the Undercarriage on the Komatsu PC 200-8 Excavator unit is the Track adjuster component where the piston rod cylinder is rusted and the seal is brittle resulting in fluid leakage. This is known when an inspection is carried out after the disassembly of the Track adjuster is carried out.Damage that occurs to the piston rod cylinder and seal interferes with the work of the Track adjuster due to lack of lubrication.Repairs made to the piston rod cylinder were to clean the rust using sandpaper until it was clean again, while the brittle track adjuster seal could not be repaired so it had to be replaced with a new seal kit

Analisa Sistem Hydraulic untuk Mengetahui Daya Hydraulic Pump pada Komponen Kerja Excavator Komatsu PC130f-7

The operation of an excavator requires a variety of operations from work components. Operation of the excavator work components requires hydraulic power. Excavator work components consist of swing motor, travel motor, boom, arm and bucket. Basically, the hydraulic system is a system for transferring and controlling force and movement with liquid fluid. Pressurized oil from the pump is distributed to various kinds of excavator work components. To find out the power that occurs requires a large flow rate and pressure on the work components. Power is in kW, flow rate is in m3/second, and pressure is in N/m2. The power produced by a variable displacement pump is 130.848 kW. The power generated by the Hydraulic Pump is then distributed to work components including a hydraulic swing motor of 7,586 kW, a hydraulic travel motor of 26,512 kW, a hydraulic cylinder boom of 32,888 kW, a hydraulic cylinder arm of 18,209 kW, and a hydraulic cylinder bucket of 15,273 kW. The total amount of power distributed to the work components is 100,468 kW. When compared with the hydraulic pump power of 130,848 kW, the power used is 77,952% of the hydralic pump power
