The main thrust of this study was to design and assess the performance of the Hydraulic Jack Operated Valve Spring Compressor and Mechanical Valve Spring Compressor. This study employed experimental design. This was conducted in the Automotive Shop of the Main Campus of Bohol Island State University (BISU), Tagbilaran City.
The participants were the 3 automotive instructors, 5 technicians and 22 automotive technology students in the year 2011. The researchers used an observation guide and questionnaire to gather data. The data were interpreted through the use of the t-test to determine its significance. The findings revealed that the Hydraulic Jack Operated Valve Spring Compressor could remove and install valves in a shorter time as compared to the Mechanical Valve Spring Compressor. Moreover, there was a significant difference between the respondents’ perception in terms of the safety of the device. The researchers concluded that experimental device could perform better and was safer to use than the conventional device. The researchers recommended the following: Automotive Instructors and Service Technicians may make use of the experimental device instead conventional device as this would save them time in finishing the concerned job. Moreover, the use of the said device ensures them working safely and effectively. Automotive instructors may consider the Hydraulic Jack Operated Valve Spring Compressor as an additional instructional tool in their shop classes.
