Nevada High School agriculture mechanics students have been logging in extra hours rebuilding a John Deere diesel engine. Skills learned by the students include using a dial indicator to measure cylinder liner protrusion, setting torque specifications for fasteners, measuring bearing tolerances, installation of cylinder liners with oil and coolant control seals, installation of crankshaft wear sleeve with seal, using special tools, setting intake and exhaust valves, camshaft to crankshaft timing marks, clutch pressure plate disassembly and reassembly with adjustment, and injection pump timing. The engine is going back into a John Deere 3010 tractor that belongs to Ted Lambi. The tractor and engine parts arrived to the Nevada High School ag mechanics lab entirely disassembled in late spring of 2018. The project has been challenging, but very educational. Dave Hobbs, retired mechanic, has been assisting with his technical expertise.


Kevin Cooper, Nevada High School agriculture education instructor and FFA advisor, has also instructed and supervised all phases of assembly. A heavy duty OTC diesel rotating engine stand was provided by the Nevada Van Wall Equipment store. Students fabricated an attachment plate for the engine to mount within the engine stand.
