B. Lubricate threads of cartridge valve with clean
hydraulic oil. Thread cartridge valve carefully into
correct manifold port. The valve should go in easily
without binding.
CAUTION
Abrupt movement of internal spools can cause
stored fluid to be released suddenly.
C. Torque cartridge valve using a deep well socket
to values identified in Figure 46.1.

Clean cartridge valve by submerging valve in clean
mineral spirits to flush out contamination. Particles as
fine as talcum powder can affect the operation of high
pressure hydraulic valves. If cartridge design allows,
use a wood or plastic probe to push the internal spool in
and out 20 to 30 times to flush out contamination. Be ex-
tremely careful not to damage cartridge. Use com-
pressed air for cleaning.

A. Carefully install coil onto the cartridge valve.
B. Install nut and torque nut to 5 ft--lb (6.7 N--m).
12.If flow control cartridge valve was removed, install
rotary handle to valve stem (Fig. 46.2):

If mow/backlap spool was removed from mow man-
ifold, install spool:
A. Placehandlebaseonflowcontrolvalve andposi-
tion alignment mark on base with number 1 on man-
ifold. Secure base with two (2) set screws. Apply a
light coating of grease to chamfer on top of base to
ease seal installation.
A. Install O--rings and back--up ring to upper
grooves on spool. Apply a light coating of grease to
O--rings.
B. Carefully push spool down into mow manifold
port until lower O--ring and back--up ring groove is
exposed on bottom of manifold. Install lower O--ring
and back--up ring to spool. Apply a light coating of
grease to O--ring.
B. Make sure that sleeve bearing is in handle cap. If
necessary, press sleeve bearing into cap. Install lip
seal on cap with seal lip facing down.
C. Place bushing onto cartridge valve stem. Use a
small amount of grease to keep bushing toward the
top of the valve stem.
C. Carefully raise mow/backlap spool until upper re-
taining ring groove on spool is exposed on top of
manifold. Install upper retaining ring.
D. Place compression spring and detent pin into
handle cap. Use a small amount of grease to hold
detent pin in place.
D. Push mow/backlap spool down and install lower
retaining ring to spool.
E. Make sure that flow control cartridge is closed by
rotating valve stem fully clockwise. During handle
installation, DO NOT rotate valve stem or speed ad-
justment will be incorrect.
E. If handle was removed from spool, position spool
so handle location of spool is between stop pins. Ap-
ply Loctite 603 Retaining Compound (or equivalent)
to threads on handle and install handle into spool.
F. Press handle cap onto valve stem with arrow on

detent pin and spring stay positioned in cap.
F. Place ball and dowel pin in backlap switch man-
ifold port. Install new O--ring onto backlap switch.
Thread backlap switch into port and torque 15 ft--lb
(20
N--m).
G. While pressing on the cap to keep the lip seal in
place, rotate cap in a clockwise direction until the ar-
row on the cap aligns with number 1 on the manifold.
By rotating the cap clockwise, the valve will remain
closed. Install screw to retain cap.
10.Reinstall
cartridge valve into manifold:
A. Lubricate new seal kit components with clean hy-
draulic oil and install on valve. The O--rings, sealing
