FIG. 22 - Installing Detent Spring and Ball (Triple Spool Valve Shown)
FIG. 23 - Installing Four Detent Balls (Triple Spool Valve Shown)
16. Place chassis lubricant in the four detent ball holes in the pin and place the detent balls (47) in position (Fig. 23).
17. Install the detent sleeve (43), shallow bore facing out, into the detent cap (41) and secure with the snap ring (44). .
18. Tap the bronze filter (42) from the cap (41) to allow a metal rod to be placed through the cap (Fig. 24). Push the metal rod to move the ball (45) away from the four detent balls. Hold the rod steady in this position and move the cap over the four detent balls. Release the pressure on the rod, allowing the detent spring ball to move against the four detent balls, causing them to move outward into the cap to lock the assembly in place (Fig. 25). Spin the housing to be sure it is locked in place.
