fork must be replaced or rerated. Perform fork wear inspec-
tion using a BOL256N1 caliper ruler Hyster P/N 4092984
as follows. See
Figure 28 .
a. Determine normal thickness of "N" of fork using scale
or ruler portion of caliper ruler. Measurement has to be
done on fork shank using caliper ruler.
b. Position caliper at end of heel internal radius (item 4,
Figure 27 ) with opening corresponding to measured
thickness of fork shank in Step a above. (e.g. for N 1.75
use N 1.75 opening). This is typically the section of fork
where wear is greatest. Note that opening distance has
been reduced by 10% from nominal thickness.
c. If fork enters opening, it is mandatory to replace it.
DANGER OF BREAKING. Furthermore, a 10% reduc-
tion in fork blade thickness results in 20% reduction in
operating capacity.
