2
Clutch Wrench

• A hand tool used to remove the starter clutch on
  small gasoline engines.

3
Compression Gauge

• Used to check compression pressures of the
  cylinders on internal combustion engines.

4
Cylinder Deglazer

• An abrasive tool used to remove the glassy glaze
  from the cylinder wall of an internal combustion
  engine.

5
Dial Indicator

• A precision micrometer type instrument that gives
  an exact reading as the needle moves around the
  dial face.

6
Dwell-Tachometer

• Combination meter used for measuring contact
  dwell and engine rpms.

7
Feeler Gauge

• A precision measuring tool used to check
  clearances between parts. Available in either
  thin blades of hardened steel or wire. The
  thickness of the thin blades or wire is marked in
  thousandths of an inch or in millimeters.

8
Flywheel Holder

• Used to hold the flywheel on small gasoline
  engines when the starter clutch is being removed
  or installed.

9
Flywheel Removal Tool

• Designed to assist in the removal of the
  flywheel. It fits over the end of the crankshaft
  and with a sharp blow(s) on the tool with a ball
  pein hammer, will dislodge the flywheel from the
  taper portion of the crankshaft.

10
Micrometer

• A precision measuring tool that will give
  readings accurate to within ten thousandths of an
  inch.

11
Piston Compression Ring

• Seals the gap between the cylinder and piston
  wall so that combustion will take place.

12
Piston Oil Ring

• Carries oil up and down the cylinder wall in an
  internal combustion engine.

13
Piston Scraper Ring

• Scrapes and cleans the walls of the pistion in an
  internal combustion engine.

14
Power Timing Light

• Used to indicate the correct timing of the
  ignition of a spark ignition engine. The timing
  light is connected to the secondary circuit which
  produces flashes of light with the firing of a
  specific spark plug. Generally connected to
  number 1 cylinder.

15
Puller Set

• Used to remove bearings, pulleys, and other shaft
  hugging instruments.

16
Ridge Reamer

• Tool used to cut away the ring ridge at the top
  of the cylinder.

17
Ring Compressor

• A tool designed to force piston rings inward into
  their grooves so that the piston and rings can be
  inserted into the engine cylinder bore.

18
Ring Expander

• A tool designed to force piston rings outward so
  the rings can be removed or installed.

19
Small Hole Gauge

• This adjustable gauge is used to measure the
  inside diameter of small holes. The gauge is
  adjusted to the hole diameter and then measured
  with an outside micrometer.

20
Spark Plug

• A device that carries the ignition spark into the
  engine combustion chamber.

21
Spark Plug Gauge

• Used to adjust the terminal gap on a spark plug.

22
Spark Plug Wrench

• A specially designed deep socket with an internal
  cushion to protect the porcelain body of the
  spark plug when tightening.

23
Small Engine Tachometer

• Used to indicate speed of engine in revolutions
  per minute (rpm).

24
Telescoping Gauge

• Used to measure the inside diameter of cylinders
  or large bores with the aid of an outside
  micrometer.

25
Torque Wrench

• Used to draw or tighten nuts, cap screws, and
  other various bolts up to specified tension by
  measuring the torque.

26
Valve Spring Compressor

• Used to compress the valve spring in order to
  remove or install valve retainer.

27
Sleeve Bearing

• A machine bearing in which the axle or shaft
  turns in a sleeve that is often grooved to
  facilitate distribution of lubricant to the
  bearing.

28
Ball Bearing

• A bearing consisting of a number of hard balls
  running in grooves in the surfaces of two
  concentric rings (races), one of which is mounted
  on a rotating or oscillating shaft or the like.

29
Roller Bearing

• A bearing that uses cylindrical rollers to
  prevent friction between machine parts.

30
Needle Bearing

• A bearing in which long rollers of very small
  diameter fill the race without a cage to provide
  spacers between them.

31
Bearing Race

• The elements of any roller-type bearing ride on
  races. The large race that goes into a bore is
  called the outer race, and the small race that
  the shaft rides in is called the inner race.

32
Oil Seal

• A device with a hard outer ring and an inner
  flexible rubber ring. The shaft is inserted
  through the inner ring, which creates a tight
  seal, preventing the entry or escape of oil from
  place to another.
