Small engine repair is repair of engines in devices that can range from lawnmowers to weed whackers to chainsaws, and everything in between. Due to the fact that there are such a wide variety of applications of the small engine, a course in small engine repair is much more likely to stick to basic concepts instead of concerning itself with how to repair specific engines in specific equipment.
Here is a general list of things generally covered in Small Engine Repair Training:
Tools and Safety
Before you ever begin to work on any sort of engine, an understanding of how to do so safely is important. Much like a shop class where you never touch the machines until you’re aware of how to safely use them, or how when you get your driver’s license you don’t drive the car until you get your temporary license, you need to know how to disconnect an engine and make it safe to work on. A failure to understand the safety steps leads to injuries, and in the case of engines, injury can include disfigurement or the loss of a digit or other appendage.
At the same time, you will be learning about the proper application for the tools of the trade. This is not only important from a safety standpoint, but also because improper use of your tools can damage the tools and the engine that you’re working on. These two concepts form the cornerstone of training on working with a small engine.
Small Engine Basics
Before you can work on a small engine, you need to understand the small engine. That means an understanding of the parts inside, along with how they interact. A few important things you can learn in training include:
- The purpose of fasteners, sealants, and gaskets
- The basics of electricity and magnetism
- How an electric charge starts a small engine
- How a spark plug works
You’ll also learn important lessons to help you when you’re repairing engines, including things like the difference between two and four-stroke engines.
Parts of The Engine
Making a small engine function properly again requires not just knowledge of the basics, but an understanding of how the basic parts come together and work as a whole. Other integral parts of the can include:
- Ignition Systems
- Cooling Systems
- Air Flow Systems
- Fuel Systems
- Cylinders, Crankshaft, and Pistons
An understanding of these parts of the engine will help you to understand the design of most small engines you will encounter, and to be able to fix them.
Application of Concepts
Finally, a good small engine repair training course will provide a few examples to illustrate the concepts above, ensuring that not only do you understand engine repair, but you understand the application of the engine, how it works, and how you are likely to see it in use. This can include:
- Lawn and brush equipment, like a weed trimmer
- Lawn and garden tractors
- Personal watercraft
The engines in these devices are not just a great way to see the practical application, but also a good method for checking that you’re learning the proper skills for small engine repair and that you’re mastering them.
This is a good layout for a general small engine training course. It should serve as a bare minimum for what you’re looking for in such a course.
