Mow/Backlap Spool Service (Fig. 77)
1. To remove backlap spool (item 17) from mow control
manifold:
A. Remove backlap switch (item 8) from mow con-
trol manifold before removing mow/backlap spool.
Remove dowel pin and ball from manifold port after
switch is removed. Remove and discard O- ring from
switch.
B. Remove lower retaining ring from backlap spool.
Raise backlap spool to allow access to retaining ring
on upper end of spool. Remove upper retaining ring.
C. Push spool down until O- ring and back- up ring
are exposed on bottom of mow control manifold. Re-
move lower O- ring and back- up ring from spool.
D. Pull spool up and out of mow control manifold.
Remove O- rings and back- up ring from spool.
E. Discard removed O- rings and back- up rings.
2. To install backlap spool (item 17) from mow control
manifold:
A. Install O- rings and back- up ring to upper
grooves on backlap spool. Apply a light coating of
grease to O- rings.
B. Carefully push backlap spool down into mow con-
trol manifold port until lower O- ring and back- up ring
groove is exposed on bottom of manifold. Install low-
er O- ring and back- up ring to spool. Apply a light
coating of grease to O- ring.
C. Carefully raise backlap spool until upper retaining
ring groove on spool is exposed on top of manifold.
Install upper retaining ring.
D. Push backlap spool down and install lower retain-
ing ring to spool.
E. If handle was removed from spool, position spool
so handle location of spool is between stop pins in
manifold. Apply Loctite 603 Retaining Compound (or
equivalent) to threads on handle and install handle
into spool.
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 20 ft- lb
(27 N- m).

Manifold Plugs (Fig. 78)
NOTE: The mow control manifold uses several zero
leak plugs. These plugs have a tapered sealing surface
on the plug head that is designed to resist vibration in-
duced plug loosening. The zero leak plugs also have an
O- ring as a secondary seal. If zero leak plug removal is
necessary, lightly rap the plug head using a pin punch
and hammer before using an allen wrench to remove the
plug: the impact will allow plug removal with less chance
of damage to the head of the plug.
IMPORTANT: An orifice is located beneath the plug
in mow control manifold ports OR1 and OR2. If an
orifice is removed from these manifold ports, make
sure to label its position for assembly purposes.
When installing the orifice in the manifold, make
sure that the orifice is properly tightened in the port.
1. Remove plugs as needed. Discard O- ring after plug
removal.
2. Lubricate and place new O- ring onto removed
plugs. If plug was removed from port OR1 or OR2, make
sure that orifice is correctly installed before threading
plug into manifold. Install plugs into manifold openings.
Torque #4 plugs to 20 ft- lb (27 N- m) and #6 plugs to 25
ft- lb (34 N- m).
