Lightly coat the gear journals with grease. When

placing the Port end housing

(figure 42)

over gears,

use

caution

so you don't hit and damage gear shaft journals.

Place the bearing carrier onto gear shaft journals of the
drive and the driven gears.

Be sure to align the dowel pin

holes

over with dowel pins. When the parts are parallel

squeeze them together or alternately tap over each dowel
until the parts are together.

DO NOT

use excessive force to

put housing together, if light taping won't do it something
is wrong

(figure 42).

MAKING CERTAIN

the marks made

to keep the components in the same orientation when re-
assembled are aligned

(figure 13 & 14)

17.

Thread the bolts & lockwashers in through shaft end

cover of gear housing until threads are started into bearing
housing. Alternately tighten the bolts in increments that
will make the three components pull down evenly

(figure

42 & 43).

Torque the bolts in increments until the bolts

(qty

are torqued to

200 ft. lbs.

Install the manifold block to top of the motor. The

manifold block on the LH and RH wing are the same and will
mount with the return line toward the front of the mower. The
manifold block for the center motor will only work with the
center motor and is installed with the relief cartridge toward
the front on the LH side. The Wing motors use two large O-
Rings and one small O-Ring on each manifold, The center
motor uses two large O-Rings to install manifold block.
When tightening the four retaining bolts, they MUST be
tightened evenly in increments so block remains un-
distorted.

DO NOT over tighten any one bolt

it will distort

aluminum manifold block. Torque the 5/16" Gr 5 bolts to 16
to 20 ft. lbs.

(figure 45. 46 & 47).

. The flat side of the seal should face down with the relief groove of

thrust plate facing the gears. Check the gear housing gasket seal

(figure 15)

is still in place on gear housing

(figure 36).
