SECTION II. TRACTOR PREPARATION

Follow the instructions in Section II of the optional Front Hitch System Attachment Owner's
Manual for preparing the tractor for installation.

SECTION III. INSTALLATION

These instructions describe installation of the Fourth Hydraulic Valve Service Kit after the
optional Front Hitch System Attachment and optional Hydraulic Angling Attachment OR optional
3 Point Hitch Attachment has been installed on the tractor. As the Fourth Hydraulic Valve Service
Kit is being installed along with the Hydraulic Angling Attachment OR 3 Point Hitch Attachment,
refer to the installation instructions in the Operator's Manual that came with all the optional
attachments as you complete each of the following steps. Some instructions in one manual may
either supersede or supplement instructions in the other.
NOTE: Place a pan beneath the tractor to catch any hydraulic fluid, which may spill during
disassembly.
A)
Remove and retain the hex screw and valve clamp securing the hydraulic tube (From Steering
Pump to Auxiliary Valve) to the auxiliary valve (Center Lift Valve). See Figure 2.
B)
Remove and retain both bolts securing the steering pump port plate to the steering pump.
Pivot the top edge of the port plate backward (toward the left frame rail), bringing the plate to
horizontal. Push the port plate up and rotate the port plate counter-clockwise 90 degrees using
the main pressure line as the pivot point. Slide the port plate towards the left frame rail until
the port plate clears the hydraulic lines. Retain the steering pump port plate. Remove the
auxiliary hydraulic tube (From Steering Pump to Auxiliary Valve) and discard. Retain and
inspect O-Rings. If damaged, furnish from service parts new O-Rings as needed. See Figure 3.
