LHS Automotive

Automotive classes are industrious and diligent this semester. First year students are just finishing up small engines. They began by tearing down the small engines and studying how they operate. They learned how a four-stroke engine works, utilized precision measuring with micrometers, used Plastigauge to measure rod bearing clearance, and applied the use of feeler gauges. Students reassembled the small engines and started them.
They also learned how to fix a small dent and a chip in paint, by removing dents with a hot glue puller. Students learned the correct way to polish and wax automotive paint finishes. Automotive students also learned skills such as double and bubble flares, Heli coils, tap and die threads, and how to use calipers to measure inside and outside measurements.


Second year students have also been working diligently in the automotive shop. This semester they have learned how to use a multimeter to take measurements of amps, volts, resistance, and voltage drops. They have studied manual transmissions by tearing them down and learning how synchronizers work to change gears, and how to calculate gear ratios, and the procedures to reassemble their transmissions. The students also studied clutch systems with mechanical and hydraulic engagement.
Students took on a job of replacing a clutch in a Toyota pickup. They also removed the transmission and replaced the pressure plate clutch disk and release bearing. While there, students also replaced the engine rear main seal.
