8.
Examine the bearing in the charge pump housing for
damage and  free rotation. If  the bearing is  damaged,
replace the bearing and seal.
9.
To assemble the charge  pump, install a new O-ring
into the groove in charge pump housing.
10.
Apply transmission oil on the gerotor wheel and the
inside of the charge pump  housing. Slide the drive pin
through the hole in the pump shaft. (It is helpful to have
this hole positioned horizontally, as shown, to keep the
pin in place during reassembly.) Then slide the gerotor
wheel onto  the  pump shaft  and drive  pin so  positive
engagement results.
11.
Using  a seal  protector  for  the lip  seal,  slide the
charge pump housing onto the pump shaft and against
the side of the adjacent pump housing. Align the scribe
marks in both housings to assure proper assembly and
to prevent damage to the transmission.
Figure 21
Most Sundstrand  charge pump  housings are  marked
with the letters RH  and LH. These are used to  denote
which side of the charge pump is mounted towards the
top of the  transmission for a given  direction of engine
rotation   (i.e.  clockwise).   The  GROUNDSMASTER
mower application requires  that the "LH"  markings be
toward the top of the transmission. Having "LH" toward
the bottom of the transmission will result in a complete
loss of hydraulic functions.
NOTE: In place of a seal protector, use plastic wrap or
a similar material to wrap the pump shaft. This protects
the seal from possible damage when sliding it onto the
pump shaft. Apply transmission oil  on the plastic wrap
to make the seal slide freely.
12.
Secure the  charge pump housing  against the ad•
jacent housing  with four  cap screws. Tighten  the cap
screws to 12 - 15 ftlb.
IMPORTANT: Excessive pressure on the pump shaft
will shear the pin that propels  the gerotor wheel. If
the  pin  should  shear,  the  transmission  will  not
operate.
13.
Install the drive coupling and transmission hub to the
engine  pulley; refer  to "Installing  Drive  Couplings" in
Chapter 10.
14.
Since some oil has drained out of the transmission
when the charge pump was serviced, check the oil level
in axle housing. Start the engine and let it run for about
one or two minutes. Then turn the engine off and check
oil level in the axle housing again.  Also check the seal
in the charge pump for oil leaks.
