NOTE: To simplify the installation of the pump block,
wrap a rubber band snugly around the pistons. This is
intended to hold the pistons in their bores as the block kit
is handled during installation.
8. With the swashplate in the neutral (0 angle) position,
lubricate the running surfaces and install the cylinder
block assembly onto the pump input shaft. Make sure
the splines engage properly. Remove the rubber
band at this time.
9. Install the pinion gear and washers onto the jack-
shaft. Install the jackshaft assembly into the housing
and torque the bolts to 120 in. lbs. to 170 in. lbs.
Use Loc-Tite solution on the bolts.
10.Install the aligning pins (A, Figure 26a and 26b) and
the bypass actuator into transaxle housing. Align
the straight (flat) edge (C) of the bypass actuator
(B) with the casing boss (D) or the bypass plate
will be damaged.
