Figure 2-12.—Torque adapters.
Figure 2-13.—Torque adapters and points of measurement.
An easy to remember rule of thumb is that the
applied torque will be greater than the indicated torque
by an amount equal to the length of the adapter
compared to the length of the torque wrench. For
example, if the adapter is the same length as the torque
wrench, the applied torque will be twice as great as the
indicated torque. If the adapter is one-third as long as
the torque wrench, the applied torque will be one-third
greater than the indicated torque.
Figures 2-14 and 2-15 illustrate how to calculate
applied torque.
RIDGE REAMER
A ridge reamer is used to remove ridges formed at
the tops of cylinders produced by piston rings moving
up and down in the cylinders. Figure 2-16 illustrates a
typical ridge reamer.
The ridge reamer consists of a carbon cutter,
adjustable guides, adjustable cutter head, adjustable
cutter, and threaded feed screw.
Whenever you use a ridge reamer, you must wear
eye protection, such as a face shield or goggles.
