feature make this type of wrench more apt to slip
off the fastener, damaging the part and possibly
injuring your hand.
These wrenches are directional; the solid jaw
must be the one transmitting the force. If you use
the adjustable jaw to transmit the force, it may
loosen, allowing the wrench to slip off.
Adjustable wrenches come in several sizes but
a 6- or 8-inch size is recommended as an all-pur-
pose wrench.
Socket Wrenches
This type is undoubtedly the fastest, safest and
most convenient to use. Sockets which attach to
a ratchet handle are available with 6-point or
12-point openings and 114, 3/8 and 3/4 in. drives
(Figure 34). The drive size indicates the size of
the square hole which mates with the ratchet
handle.
Torque Wrench
A torque wrench (Figure 35) is used with a
socket to measure how tightly a nut or bolt is
installed. They come in a wide price range and
with a 114, 3/8, or 1/2 in. square drive. The drive
size indicates the size of the square drive which
mates with the socket.
Impact Driver
This tool makes the removal of tight fasteners
easy and reduces the chance for damage to bolts
and screw slots. Impact drivers and interchange-
able bits (Figure 36) are available at most large
hardware, snowmobile and motorcycle dealer-
ships. Sockets can also be used with a hand
impact driver; however, make sure the socket is
designed for impact use (B, Figure 37). Regular
hand type sockets (A, Figure 37) may shatter if
used to loosen a tight fastener.
CHAPTER ONE
Hammers
The correct hammer (Figure 38) is necessary
for repairs. A hammer with a rubber or plastic
face (or head), or a soft-faced hammer that is
filled with lead or steel shot, is sometimes nec-
essary for engine teardowns. Never use a metal-
faced hammer on engine or suspension parts, as
severe damage will result in most cases. You can
produce the same amount of force with a soft-
