<![CDATA[PT United Tractors Tbk Jakarta workshop held a lot of Machine Inspection Programs for Komatsu units. During the implementation of the Machine Inspection Program (PPM) the machine inspection program is one part of the maintenance that is carried out periodically to obtain accurate data on the condition of the equipment at the time by carrying out checks and adjustments using measurement methods and diagnostic instruments The use of a pressure gauge is still using manual and has a measurement distance that is still limited, if workers or mechanics are not equipped with sufficient knowledge then the pressure gauge will have the potential for error in use and the selection of a pressure gauge is not appropriate to the pressure gauge directly connected to the hydraulic pressure through the hose then the work process ppm is not enough 1 manpower. Therefore it is necessary to modify a digital pressure gauge that has a wide range of scales, in addition a wireless connection is needed to enable the operation of the unit and measurements are made 1 manpower and Bluetooth is one of the right choices in addition to the reach can be met in an application not too difficult so that readings measurement results can be connected directly via mobile.]]>

<![CDATA[In the operation of the unit whose successor does not use a hydraulic system, the role of the clutch is very important in transmitting power from the engine to the transmission. However, the clutch can only slip so that it can no longer function to forward power from the engine to the transmission. This can be caused by several things, including: wear on the clutch material, the presence of oil in the field of clutch surface, and spring damage to the clutch. On Scania P 124 CB 8x4 NZ 420 units this slip on clutch problem also occurs so research needs to be done to find the main cause. The method used in this study is to carry out checks and measurements and then the results are compared with the standard values that have been determined. The result shows that the cause of the slip on the clutch on the Scania P 124 CB 8x4 NZ 420 unit is 1) the presence of oil that wet the coupling surface is caused by a damaged seal shaft; 2) wear on clutch components namely clutch disc and pressure plate. To keep the seal shaft in good condition, regular and regular oil changes must be made and when the replacement of the seal shaft must be in accordance with the part number so that the possibility of the same problem can be reduced.]]>
