hold.
Snap Ring Pliers
Snap ring pliers (
Figure 24
) are specialized pliers
with tips that fit into the ends of snap rings to re-
move and install them.
Snap ring pliers are available with a fixed action
(either internal or external) or convertible (one tool
works on both internal and external snap rings).
They may have fixed tips or interchangeable ones
of various sizes and angles. For general use, select
convertible type pliers with interchangeable tips.
WARNING
Snap rings can slip and fly off during
removal and installation. In addition,
the tips may break. Always wear eye
protection when using snap ring pli
ers.
Hammers
Various types of hammers (
Figure 25
) are avail-
able to fit a number of applications. A ball-peen
hammer is used to strike another tool, such as a
punch or chisel. Soft-faced hammers are required
when a metal object must be struck without damag-
ing it.
Never
use a metal-faced hammer on engine or
suspension components. Damage will occur in most
cases.
Always wear eye protection when using ham-
mers. Make sure the hammer face is in good condi-
tion and the handle is not cracked. Select the correct
hammer for the job and make sure to strike the ob-
ject squarely. Do not use the handle or the side of
the hammer to strike an object.
PRECISION MEASURING TOOLS
Each type of measuring instrument is designed to
measure a dimension with a particular degree of ac-
curacy and within a certain range. When selecting a
measuring tool, make sure it is applicable to the
task.
As with all tools, measuring tools provide the best
results if they are cared for properly. Improper use
can damage the tool and result in inaccurate results.
If any measurement is questionable, verify the mea-
surement using another tool. A standard gauge is
usually provided with measuring tools to check ac-
curacy and calibrate the tool.
Precision measurements can vary according to
the experience of the person taking the measure-
ment. Accurate results are only possible if the me-
chanic possesses a feel for using the tool.
Heavy-handed use of measuring tools produces less
accurate results than if the tool is handled gently.

tips so the point at which the tool contacts the object
