Development and Efficiency Evaluation of Hydraulic Jack Shock Absorber Removal Tool

Abstract

The objectives of this research were to: 1) develop a hydraulic jack shock absorber removal tool and 2) determine the efficiency of the hydraulic jack shock absorber removal tool. The population and the 7 samples were car maintenance technicians selected by purposive sampling technique from the company. Hondatherdphrakiet Nakhon Si Thammarat Province. The research instruments consisted of 2 parts, i.e., the experimental recording forms and the quality assessment forms. The statistics used in the research was mean and standard deviation.

The results of the research were as follows: 1) the hydraulic jack shock absorber removal tool was built based on the design. From the test results of disassembling the spring shock absorbers of various car models, the duration for the operation followed the hypothesis.  The developed tool can be used to disassemble the spring shock absorbers of various car models.  The experts agreed with the efficiency of the hydraulic jack shock absorber removal tool at very high satisfaction.  2) The hydraulic jack shock absorber removal tool can disassemble spring shock absorbers with no damage nor deforming.
