Abstract

Engine compression leakage testing is a crucial step in preventive maintenance to detect performance issues. However, conventional compression testers often have limitations in terms of accuracy and inefficient data documentation capabilities. Therefore, this research aims to modify a digital compression tester set to be a more accurate and efficient diagnostic tool for detecting compression leakage on John deere 6068 tractor engines. Testing was conducted by comparing the measurement results of the modified tool with a conventional tool on tractor engines experiencing a performance decline. Based on the research results that have been conducted, it can be concluded that the modification of the analog compression tester to a digital version has been successfully realized. The developed tool is capable of providing more accurate compression pressure measurement results with an average deviation of 0,56 % compared to the analog type of 3.88%.
