3 S HOP T OOLS Quality tools recommended by the manufacturer should be used when servicing a small gas engine, Makes service easy and effective and prevents damage to parts Common shop tools include Wrenches - Punches - Hammers Piers - Chisels Screwdrivers - Measuring Instruments

4 W RENCHES There are many types of wrenches, and it is important to use the correct tool when faced with a decision of which would be best. Box end, open end, adjustable, and socket type wrenches should be used on hexagon bolts and nuts Which is better to use if you can encompass the entire bolt head, an open or closed end wrench?

7 W RENCHES An adjustable wrench should be used as a last resort when other wrenches are not available. Adjustable wrenches are prone to loosening and slipping around the corner of bolts and nuts A torque wrench is used to tighten threaded fasteners to a specific torque setting. Torque is the turning force applied to the fastener

8 P LIERS Pliers are useful for gripping, bending, pulling, and cutting wires. THEY SHOULD NOT BE USED IN PLACE OF WRENCHES

11 S CREWDRIVERS Screwdrivers are available in a variety of shapes and sizes. Standard and phillips variety The proper size blade should be used to match the length and thickness of the screw head slot Offset screwdrivers can be used in tight situations.

14 P UNCHES Many types of punches are used for small engine work Center punch Has a point on the end, used to make depression in metal surfaces before drilling Prick punch Same as above, but the point is 60 degrees to leave a small depression prior to using the center punch Pin punch Used to drive pins Drift punch Used to align holes in mating parts

17 M EASURING I NSTRUMENTS High quality measuring instruments should always be used when servicing a small gas engine. Measurements are made to determine if parts are within specific limits or if adjustments are needed. Calipers Used to measure the diameter or thickness of an object Inside or outside Micrometers Precision instrument designed to accuratley measure engine parts

20 P ARTS OF A MICROMETER To understand how to take a reading from a micrometer, we need to know the parts. Anvil Spindle Sleeve Frame Thimble

22 S TEPS TO R EADING A MICROMETER Lightly tighten on object. Determine smallest measurement when micrometer is closed. Find largest visible number on sleeve and multiply times Count number of marks past largest visible number on sleeve and multiply times Multiply thimble reading times Add all numbers to get answer.

23 Smallest Measurement Largest sleeve reading N OW, AN EXAMPLE... One mark past largest sleeve reading Thimble Reading inches

24 Smallest Measurement Largest sleeve reading Three marks past largest sleeve reading Thimble Reading inches Another example...
