25.21.If there is a possibility of fluid contamination,
either as a cause of or a result of the pump (or
motor) failure:
• Replace the filter.
• Drain and properly dispose-of the remainder of
the fluid in the system.
• Remove and clean or replace the hoses con-
nected to the “A” and “B” ports of the pump.
• Follow break-in procedure; initial fluid change
after 50 hrs. of operation.
NOTE: If hoses are cleaned with parts-washer
solvent, follow-up with hot soapy water and hot
water rinse. Dry thoroughly before reinstallation.
The parts washer solvent is an astringent that
will remove any traces of contaminated fluid.
The soapy water is a surfactant that will remove
any grit from the lining of the hose and flush
away any remnants of solvent. Residual solvent
will very effectively thin-out hydraulic drive sys-
tem fluid.
25.22.Prior to installation, clean the area surrounding
the pump.
25.23.Affix the carriage bolts that hold the pump using
duct tape. See Figure 25.23.
25.24.Lower the pump into position over the carriage
bolts.

25.25.Prime the “S” hoses that lead from the filter, if
they have lost substantial fluid.
See Figure 25.25.
25.26.Connect the hose(s) to the “S” fitting on the back
of the pump.
25.27.Install the nuts on the carriage bolts, and secure
the pump to the frame.
• If the locking feature of the nut has worn, replace
the nut, or apply a small amount of thread lock-
ing compound such as Loctite 242 (blue) to the
threads. Tighten the bolt to a torque of 35 ft-lbs
(47.46 Nm).
25.28.Connect the remaining hoses and steering link-
age, then install the fan and drive pulley by
reversing the removal process.
• Tighten the nut holding the pulley. If the locking
feature of the nut has worn, replace the nut, or
apply a small amount of thread locking com-
pound such as Loctite 242 (blue) to the threads.
Tighten the bolt to a torque of 35 ft-lbs (47 Nm).
• Tighten the nut that secures the cooling fan. If
the locking feature of the nut has worn, replace
the nut, or apply a small amount of thread lock-
ing compound such as Loctite 242 (blue) to the
threads. Tighten the bolt to a torque of 140 in-lbs
(16 Nm).
• Tighten the nut that secures the steering rod. If
the locking feature of the nut has worn, replace
the nut, or apply a small amount of thread lock-
ing compound such as Loctite 242 (blue) to the
threads.
25.29.Re-fill the reservoir with Hydraulic Drive System
Fluid Plus.
