Checks
WARNING
Never repair damaged forks by heating or weld-
ing. Forks are made of tempered steel using spe-
cial procedures. Always replace damaged forks as
a pair.
Inspect forks for cracks and wear. Check the align-
ment of fork tips. The difference in height of fork
tips must be less than three percent of the length of
the forks. See Table 2 and Figure 8.
Some applications may require closer alignment. If
forks do not meet specification, they both must be
replaced. Repair or replace any damaged or broken
fork components and lubricate, as necessary. See
Figure 8.
