15.6 Fork spread unit
15.6.1 Servicing the fork spread unit
On usual truck servicing, the following points should be checked/car-
ried out:
• Lubrication of friction plates against fork and ball beam.
• Push grease into the grease nipples when servicing the truck. The
brass bushings in the fork sleeve and in the support rollers provide
some degree of lubrication, as they are provided with graphite in
-
lays.
• During lubrication, use a graphite grease, e.g. Q8 Rembrandt EP2.
• Check bearings and axles, and replace wear parts if there is sub-
stantial play in the fork sleeve.
• If the upper chromed axle has been damaged, this must be replaced
immediately. Wear on the lower support rollers is the result of the
forks being used frequently for lateral conveyance. In very dirty envi
-
ronments, these should be checked more often than in normal envi-
ronments.
• Check the forks. The thickness of the blade or shaft should be at
least 90% of the original thickness in accordance with ISO 5057.
• Check the screws and nuts. If necessary, tighten as normal.
