COURSE DESCRIPTION

This course is prepared to train intermediate

students who i tend to become diesel service and repair

mechanics. The tra ning includes shop manipulative

practice in addition to related classroom instruction.

Intermediate instruction includes: operation and

safety, electricity, intake and exhaust systems,

starting methods, oil and gaseous fuels, tune-up

and trouble-shooting, engine rating and performance,

mechan cal and hydraulic drives. Students who have

at least 540 hours of instruction in basic and inte

mediate courses and exhibit nece sary skills and

attitudes may be placed in the S.I.E. Program on

recommendation of the instructor.
