Cracks
Visually examine the forks for surface cracks. Pay special attention to:
Fork heel
Welds that attach mounting components to the fork blank
Forks with surface cracks should not be returned to service.
Fork Angle
Check the angle between the front vertical face of each fork and the load face of each
shank. If the deviation exceeds 3° from the original specification withdraw the fork from
service.
Difference in Height between Fork Tips
Check the difference in height between tips of the forks with the forks mounted on the
fork carriage. If the difference in tip heights exceeds 3% of the length of the blade, the
forks should be removed from service.
Positioning Lock (If Applicable)
Check the positioning lock on each fork to make sure it functions properly. If any
problems are noted, repair or replace the fork.

Wear
Two different areas of the fork and fork attachment should be checked for wear.
Fork Blade and Shank
– Check each fork blade and shank for wear, pay
special attention to the area surrounding the heel of the fork. If the thickness is
reduced to 90% of the original thickness, remove the fork from service.
Fork Hooks
– Check the support face of the top hook and the retaining faces
of both hooks for wear, crushing, and other local deformations. If any of these
deficiencies cause excessive clearance between the fork and the fork carriage,
remove the fork from service.
Fork Marking
If the fork marking is not clearly legible, the fork manufacturer, or their representative
should remark it.
Repairing Forks
If a fork needs to be repaired or replaced, return it to the manufacturer or other expert
of equal competence who shall decide if it may be repaired or if it must be replaced
with a new fork. Never try to repair surface cracks or wear by welding the fork. If you
need to reset a fork, make sure it is subjected to an appropriate heat-treatment before
it is returned to service.
