Technical Publications & Study Guides The following two sets of technical publications are of excellent quality that best represent the small engine industry. We selected these publications because they best teach the principles that are generic to all engines and not too specific for any make or model. They represent the industry standard. These sets work well in class instruction as well as individual learning. Minimum order for technical publications is $20.00 Kohler's Technical Manuals - Set of five (KOH-101) -$20.00 A Guide to Engine Rebuilding - Preliminary checks, cleaning, measuring, gaskets, sealants, oil seals, bearing care, lubrication, torquing, engine break-in, cylinder heads, cylinder blocks, valves, pistons and rings, connecting rods, camshaft, crankcase, oil pump, governor, dynamic balance, fuel pump and carburetor. Measurement Guide - Teaches the accepted practices for measuring all engine components. Engine Failure Analysis - ( full color) - Excellent for all 4-stroke engine manufacturers. Pre-disassembly: air filtration, oil, cooling, carburetor and governor. Disassembly: peripheral parts, cylinder head, oil sump, valves, piston and rings, connecting rods, bearings and more. 28 pages of color photos illustrating all the ways engines fail.. Engine Electrical Systems - Magnetos, coil ignitions and charging systems. Complete theory and operation of electrical systems and components Testing and troubleshooting included. Troubleshooting Reference - Engine Failure Analysis - Engines will not crank; cranks - will not start; runs rough at low rpm and will not accelerate; backfires at full throttle; electrical system problems; hot - will not start; cannot reach high idle; starting problems, and more. Tecumseh Technical Manual (TEC-101) $20.00 Failure Analysis - 4 Cycle Engines (full color) - An excellent book on engine component failures. It includes the evaluation process, air cleaner, carburetor, cooling system, engine oil, combustion chamber, governor gears, camshaft, counterbalance, crankshaft, connecting rod, pistons, rings, bores, no-oil start, low oil, wrong oil, overheating, gasket failure, over-speeding, dirt and grit and incorrect torquing. OPE Certification Exam Study Guide ICS-018 $20.00 . 2 Stroke & 4 Stroke Study Guide for OPE Certification. ICS-018 $20.00 A comprehensive study guide developed with, and for, the OPE industry. This study guide goes far beyond the original small study guide. This study guide presents 92 questions with answers and full discussions on why the correct answer is correct and why the other answers are incorrect. The study guide is full of photos & drawings to illustrate the discussions. This is not a book on basics, it spends the majority of the time concentrating on the more difficult areas of the OPE certification test dealing with fuels, failure analysis, torquing, governors, troubleshooting, servicing, induction and exhaust systems and professional competency. Many OPE certification committee members supplied materials and reviewed the study guide before it went to print. Graphics and technical manuals have been provided through the courtesy of the following companies: Briggs & Stratton, Echo, Homelite, Honda, Husqvarna, Kohler, Kubota, McCulloch, Shindaiwa, Tecumseh and Toro.
