AUT 114 - Cylinder Head Service II (3 CR.)

Course Description

Studies cylinder head reconditioning, including valve seat grinding, re-facing valves, servicing valve guides, valve seat inserts, cutting for valve seals and spring, thread repair and resurfacing mating surfaces. Lecture 2 hours. Laboratory 3 hours. Total 5 hours per week.

General Course Purpose

AUT 114 is designed to provide the student with a thorough knowledge of the design and performance characteristics of the upper engine assembly and valve drive mechanisms. Additionally, discussion and application includes the inspection and measurement techniques used to determine what overall operations are required. The course will provide the required machining skills necessary to completely remanufacture cylinder head and valve drive mechanisms.

Course Prerequisites/Corequisites
