1.Remove control valve from the backhoe.
2.Thoroughly clean the exterior of the valve before beginning disassembly procedures.
3.At the BOTTOM of the valve remove screws, cap and spool control kit. Keep parts in order of disas- sembly. See figure 11 for parts involved in the make- up of the spool control kit.
IMPORTANT: DO NOT remove the spool from the valve. The seals can be replaced externally. Prevent spools from rotating or moving by insert- ing a rod through the hole in the spool and using the rod as a handle. DO NOT hold the spool with a wrench. This will destroy the finish.
4.At the BOTTOM of the valve, remove the backup ring and spool
5.Thoroughly clean counterbores.
6.Install new seals:
A. Spool Control Kit Only:
All parts inside cap are lubricated with synthetic base grease NLGI1. Slide
B. Float Kit Only:
All parts inside cap are lubricated with synthetic base grease grade NLGI2. Install new
7.At the BOTTOM of the valve replace cap and screws, reversing the order in which they were dis- assembled in step 3. Torque screws to 5 ft. lbs.
8.At the top of valve remove all parts connected to the spool (handles, linkage, etc.)
9.At the TOP of the valve remove screws, flange, dust cover, backup ring and spool
10.Thoroughly clean counterbore.
11.Lightly oil new
12.Reattach all parts connected to the spool (han- dle, linkage, etc.).
ASSEMBLY
Basic components for all models can be identified in Figure 12. Refer to Page 43 for photographs of unit on shipping pallet.
General:
The backhoe has been partially disassembled and strapped to a skid for shipping purposes. Initial installa- tion on the tractor will require a hoist or other device capable of safely lifting the entire backhoe from the skid. After the initial installation is complete, the backhoe can serve as its own erecting hoist, by lowering stabilizers and bucket to the ground. Additional lifting devices will not be required for normal removal and reattaching.

IMPORTANT: Tighten all hardware to torque requirements specified in torque chart on page 45.
1.Remove the stabilizer assemblies and any miscellaneous items which have been fastened to the skid and arrange conveniently.
CAUTION 
DO NOT cut any strapping that fastens the backhoe mainframe and swing frame to the skid base at this time
2.Support boom (A) and dipperstick (B) with hoist attached at (C) and remove boom transport lock pin. Lower boom and extend dipperstick until end of dip- perstick is approximately 16” above the ground. Move control handles to “BOOM DOWN” position and “CROWD OUT” position as required to aid movement.
CAUTION 
Be sure hoist being used is suit- able, has sufficient capacity and is in the proper position. Do not allow anyone under a backhoe member supported by hoist.
