by rubbing it with 300 to 600 grit sandpaper on a
flat surface.

motor cylinder. Be very careful not to drop or
damage valve plate. Inspect valve plate surface for
scratches. If damaged, replace.

Reassembly
1. Fig. 5. Install plate seal (12) and valve plate (7) on
motor cylinder (1). Be sure surface of valve plate
facing out is free of scratches or damage. Install
screws (28), and torque them oppositely and
evenly from 4 to 6 in-lb (0.5 to 0.7 N
S
m).
NOTE: Before reinstalling the valve housing (4),
be sure spool (5) is fully shifted to one side and
foam pieces (63) are in place.
2. Grease o-ring grooves in valve housing, then
install large o-ring (20) and two small o-rings (30).
Grease holds o-rings in place during assembly.
3. Grease air cup (6) and valve plate. Orient air cup
as shown. Place air cup on valve plate so its
position corresponds to position of spool.
4. Place valve housing on motor cylinder. Spool must
engage air cup, or valve housing assembly will not
fit correctly. If necessary, move air cup to engage
spool.
5. Install screws (24), and torque oppositely and
evenly from 14 to 17 in-lb (1.6 to 1.9 N
S
m). Be
sure o-rings (20, 30) do not slip out of grooves on
valve housing.
