Reassembly into the “A3” configuration:

1. Align the retaining plate (LV60) so the anchor point is below the 1

spool

2. Install the retaining plate (LV60) flush against the valve with the anchor point facing away from

the valve

3. With a 1/8” Allen wrench, install the two (2) button head cap screws (P1984) that secure the

retaining plate (LV60) to the valve.

4. Install the first studded rod end (P2108) into the retaining plate (LV60) with the socket end

facing the second spool

a. This is the right side when viewing the valve with the joystick facing towards you

5. With a 7/16” wrench, secure the studded rod end (P2108) with one (1) 7/16” hex nut (LV14) to

the retaining plate (LV60)

6. Install the second studded rod end (P2108) and the spool bushing (LV30) in the spool directly

above the retaining plate anchor

7. Rotate the installed studded rod end (P2108) and the spool 90° CW (clockwise)

a. The threaded ends of both the studded rod ends (P2108) should be pointing in the

same direction

8. With a 7/16” wrench, secure the studded rod end (P2108) with one (1) 7/16” hex nut (LV14) to

the first spool

9. Rotate the 2

spool until it is perpendicular to the 1

spool

a. If you are converting from “A2” to “A3”, this was done during disassembly

10. Install the threaded end of the spool pivot (LV67) thru the bottom of the 2

spool

11. With a 7/16” wrench, secure the spool pivot (LV67) to the 2

spool with a 7/16” hex nut (LV14)

a. When installed the threaded end of the spool pivot and hex nut will point upward in the

same direction as the fluid work ports

12. Align the small grooves in the rod end retaining plate (LV66) with the flats in the tapped end of

the studded rod ends (P2108) already installed

13. With a 5/32” Allen wrench, secure the rod end retaining plate (LV66) to the studded rod ends

using the two (2) small button head cap screws (P1985)

a. When installed, the flat on the rod end retaining plate will face to the right, when looking

at the valve with the joystick facing you.

b. If you just disassembled the “A2” configuration, the joystick handle link (LV69) will still

be attached to the rod end retaining plate (LV60)

14. Install the socket end of the spherical rod end (LV68) into the spool pivot (LV67)
15. With a 3/16” Allen wrench, secure the spherical rod end (LV68) to the rod end retaining plate

(LV66) using the large button head cap screw (S048)

16. With a 9/16” wrench, install the joystick handle link (LV69)

a. If you just disassembled the “A2” configuration, skip this step and continue to Step #17

17. Slide the rubber joystick boot (LV27) over the joystick mechanism with the square end of the

boot facing the valve until the retaining plate (LV60) rests in the first groove of the rubber
joystick boot and the joystick handle link (LV69) is thru the round hole of the rubber dust boot.

18. Install the handle assembly (LV11, LV21 & LV40) into the joystick handle link (LV69)
19. Secure the handle assembly (LV11, LV21 & LV40) by tightening the 9/16” hex nut (LV11)

The joystick is now converted to the “A3” configuration.
