Steer Fork Assembly
Removal
NOTE
To allow for the removal of the steer fork from
the lift truck, the entire lift truck must be at
least 27" off the floor. The steer fork assembly
is 36" long. If the truck is not 27" off the floor,
there is not enough clearance to remove the
steer fork from the truck.
1.
Disconnect and remove the battery.
Discharge the capacitors.
2.
Remove the control cover and the control
cover mount bracket. Remove the hydraulic
motor (it is not necessary to remove the
hoses) and steer position potentiometer.
CAUTION
The lift truck, without a battery weighs from
6,000 to 8,000 pounds. Use a lift or stands
with adequate capacity.
3.
Raise and safely support the entire lift truck at
least 27" off the floor.
CAUTION
The steer fork assembly must be supported
prior to removing the lock nut. If the steer fork
assembly is not supported, serious damage to
the lift truck or the steer fork may occur.
Personal injury is also possible.
4.
Use a 5/16” eyebolt and chain that will fit
through the lock nut to support the steer fork.
Remove the lock nut and lower the fork out of
the truck.
NOTE
During the removal and installation of the
steer fork, use care to avoid damaging the
bearing seals or the threads and splines on
the steer fork shaft.
5.
Lower the steer fork assembly to the floor and
remove it.
Replacement
NOTE
The steer fork must be installed with the stop
pin toward the forks.
1.
Put the lower bearing in place and drive the
lower seal into position with the lip facing
down.
2.
Put the upper bearing in place and drive the
upper seal into position with the lip facing up.
Stack the lower machine bushing, steer gear,
upper machine bushing and lock nut in
position.
3.
Thread the eyebolt and chain through the
stacked parts and screw it into the steer fork.
4.
Carefully raise the steer fork into position.
Tighten the lock nut to 60 lb-ft. Make sure the
steer fork can rotate freely.
5.
Lower the lift truck to the ground. Install the
hydraulic motor and steer position
