5.
Check the fork blade (J) and shank (H) for wear with
special attention to the heel (G). The fork should be
withdrawn from service if the thickness is reduced to
90 percent or less of the original thickness.
Fork blade length may also be reduced by wear,
especially on tapered forks and platens. Remove the
forks from service when the blade length is no
longer adequate for the intended loads.
6.
Check the fork mountings (K) for wear, crushing and
other local deformation, which can cause excessive
side to side wobble of the forks. Excessive
clearance on hook type forks may allow them to fall
from the carrier. Forks which show visible signs of
such damage should be removed from service.
7.
Check the positioning lock and other fork retention
devices to make sure they are in place and working.
Hook type forks use a spring loaded pin (M),
located in the top hook, to engage notches in the
top carriage bar to hold the fork in place.
When adjusting the fork spacing, the forks are
prevented from sliding off the end of the carriage by
stop blocks. These stop blocks are at both ends of
the carriage and in the path of the bottom fork hook.
The load backrest extension may be used in place
of the stop blocks in some cases.
Shaft mounted forks may use set collars or spacers
on the shaft to either side of the fork. They may
also use U bolts, pins, or similar devices which
engage the fork through the top structure of the
carriage.
8.
Check fork markings (N) for legibility. Renew
markings as required to retain legibility.
9. a.
Lift the mast and operate the tilt control lever, until
the top surface of the forks is parallel with the
floor. Place two straight bars that are the same
width as the carriage, across the forks as shown.
b.
Measure the distance from the bottom of each
end of the two bars to the floor. The forks must
be parallel within 3 mm (.12 in) for Full Tapered
and Polished (FTP) forks, all other forks 6.4 mm
(.25 in), for their complete length.
c.
Put one fork, one third from the tip, under a
fixture that will not move. Then operate the tilt
control with caution until the rear of the truck lifts
just off the floor. Follow the same procedure
with the second fork. Repeat Step a.
