How to Remove the Yoke
and Drive Motor Assembly
When removing a hose assembly
or fitting, the fitting and/or hose
end must be torqued to
specification during installation.
Refer to Section 2, Hydraulic Hose
and Fitting Torque Specifications.
1 Block the wheels at the non-steer end of the
machine.
2 Remove the cotter pin from the wheel castle nut
at the steer end of the machine.
Always replace the cotter pin with
a new one when removing the
castle nut.
3 Loosen the wheel castle nut. Do not remove it.
4 Center a lifting jack under the drive chassis at
the steer end of the machine.
5 Raise the machine approximately
6 inches / 15 cm. Place blocks under the
chassis for support.
Crushing hazard. The chassis
could fall if not properly supported.
6 Remove the wheel castle nut. Remove the
wheel.
7 Tag, disconnect and plug the hydraulic hoses
on the drive motor. Cap the fittings on the drive
motor.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to squirt
or spray.
Component damage hazard.
Hoses can be damaged if they are
kinked or pinched.
8 Support and secure the yoke assembly to an
appropriate lifting device.
9 Remove the retaining fastener from the steer
link at the yoke assembly.
Note the quantity and location of
the spacers when disconnecting
the steer link from the yoke
assembly.
10 Remove the retaining fastener from the rear of
the yoke pivot shaft.
The pivot shaft retaining fastener
is located below the main deck.
