D)Take the template bracket (A) from the service kit. Locate the hole in the LH tractor frame, as shown in figure 4, and align the pivot pin on the template bracket (A) with the hole in the frame. Rotate the template bracket (A) counter-clockwise until the second pin on the template bracket (A) contacts the frame. See Figure 5. Hold the bracket in position and use a center punch to mark the center for the two holes. Remove bracket.

E)Using a 9/16 inch drill bit, drill the UPPER hole in the frame. Using a 9/32 inch drill bit, drill the LOWER hole in the frame.

F)Take the valve assembly and note the position of the mounting brackets. Remove and discard the four hex cap screws and four lock nuts fastening the hydraulic valves together. Retain the valve mounting brackets from the valve assembly.

G)Follow the installation instructions from the Operator’s Manual that came with the optional attachments to assemble the valves. Refer to the picture in figure 6 to verify proper assembly. If existing O-rings were damaged during disassembly, use the Back-up O-rings

(C) and O-rings (D) from the service kit. Use the four ¼ inch Hex Cap Screws (B) and four ¼ Hex Lock Nuts (M) from the service kit to assemble the four valves together along with the mounting brackets previously removed.

NOTE: Install the fourth valve body (use valve from the optional attachment) IN FRONT of the center lift valve with the outlet ports of the valve body facing inward. Install the front hitch valve and angling valve with the outlet ports of the valve body facing outward.

IMPORTANT: The spool must be correctly positioned in the valve body to ensure proper operation of the valve. All four valves must have the arrow on top of the valve spool pointing to the rear of the tractor when installed into the chassis.
