Impact Drivers
An impact driver provides extra force for
removing fasteners by converting the
impact of a hammer into a turning
motion. This makes it possible to
remove stubborn fasteners without
damaging them. Impact drivers and
interchangeable bit (Figure 10) are
available from most tool suppliers.
When using a socket with an impact
driver, make sure the socket is designed
for impact use. Refer to Socket
Wrenches, Ratchets and handles in this
section.
WARNING
Do not use hand sockets with air or
impact tool because they may shatter
and cause injury. Always wear eye
protection when using air or impact
tools.
Allen Wrenches
Use Allen or setscrew wrenches (Figure
11) on fasteners with hexagonal
recesses in the fastener head. These
wrenches are available in L-shaped bar,
Socket and T-handle types. A metric set
is required when working on most
UTV’s. Allen bolts are sometimes called
socket bolts.
Torque Wrenches
Use a torque wrench with a socket,
torque adapter or similar extension to
tighten a fastener to a measured torque.
Torque wrenches come in several drive
sizes (1/4, 3/8, 1/2 and 3/4) and have
various methods of reading the torque
value. The drive size indicates the size
of the square drive that accepts the
socket, adapter or extension. Common
methods of reading the torque value are
the deflecting beam, the dial indicator
and the audible click (Figure 12). A
torque wrench is a precision tool that
must be properly cared for to remain
accurate. Store torque wrenches in their
case or separate padded drawers within
a toolbox. Follow the manufacturer’s
instructions for their care and
calibration.
