Supplement for CEV Video #883 Small Gas Engine Assembly - I is the first in a three-art series on the proper techniques and procedures necessary for the assembly of a 5 horsepower Briggs and Stratton Model 124702 engine. This series incorporates CEV’s VideoActive format, which creates an interactive learning environment by incorporating questions and discussion into each program. Sections are color and numerically coded to make selection or review of a topic much easier and faster. Following each section, a short quiz is presented. A comprehensive final quiz is presented at the end of the tape. This teaching guide contains copy-ready student quizzes, a teacher’s key, and an outline for performing the assembly procedures demonstrated in this tape. Skills Demonstrated: Dr. David Lawver, Associate Professor of Agricultural Education and Communications at Texas Tech University, demonstrates installation of the crankshaft, checking ring gap, assembly and installation of the piston and rings, tappets, camshaft, oil slinger, and sump. Dr. Lawver emphasizes the importance of removing all gasket residue and lubricating all bearing surfaces. It is recommended that this video be used with the repair/service manual published by the manufacturer. Because this tape focuses on one particular engine model from Briggs and Stratton, a condensed table of specifications is provided in this guide. However, this table should not be used in place of the complete discussion found in the manufacturer’s repair manual. This teaching guide follows the tape presentation. The assembly outline briefly describes the procedures performed and includes remarks concerning the tools that are used to complete the procedure and any special instructions are listed. This format enables the viewer to follow along with the tape, and it serves as a guide when performing the assembly procedures after viewing the tape.
