Control Valve No. 4 Spool Detent Replacement (Fig. 30)
NOTE: The control valve assembly must be removed to
replace this assembly. (See Control Valve Removal and
Installation in this section of the book.)
1. Be sure No. 4 spool is in neutral and remove the
bonnet, large spring, and stop collar.
2. Hold one hand in front of detent sleeve and push the
front of the spool in very slowly until the detent balls pop
out. Be sure to remove all four (4) balls.
3. Push the front of the spool in carefully until the holes
in the detent adapter are just past the edge of the detent
sleeve.
IMPORTANT: Do not push the spool too far or the
rear spool seal may be cut by the spool.
4. Hold the front of the spool from turning, insert a drift
punch through the holes in the adapter and rotate the
adapter counter-clockwise to remove it from the spool.
5. Remove the detent sleeve.
Reassemble With the Following Procedures:
1. Mount the detent sleeve and the detent adapter. Lock
the adapter securely to the spool.
2. Apply a light coat of grease to the adapter holes, insert
the small spring, the four balls, and the ball follower.
3. Stand the valve bank assembly up so the front (clevis
end) of No. 4 spool is facing downward.
4. Slide the detent sleeve up to the four balls. Apply light
pressure against the balls with the sleeve. Push against
the center of the ball follower with a drift punch to allow
the balls to slip into the adapter holes and the sleeve to
slide over the assembly.
IMPORTANT: Do not push spool too far or the rear
spool seal may be cut by the spool.
5. Assemble the stop collar, large spring and bonnet to
the valve body. Check the spool for proper detent op-
eration and mount the valve bank onto the machine.
6. Adjust the traction switch. (See Traction Switch Re-
moval, Installation and Adjustment in the Repairs sec-
tion of Chapter 5 - Electrical System.)
