(H6400C, H6400C1 & VSD6400)
Refer to the Illustration(s) and Parts List for correct
orientation and placement of parts.
Replace any O-rings, V-rings, seals, and gaskets on
parts that have been disassembled. Apply hydraulic
fluid or O-ring lubricant to all O-rings and all metal
surfaces which they must slide over. When installing an
O-ring which must slide over sharp surfaces, use a
rolling motion and be careful not to damage the O-ring.
Wherever the assembly results in metal-to-metal
contact, coat the surfaces with hydraulic fluid or O-ring
lubricant.
Some steps of the assembly procedure require a
removable type of thread sealing and locking com-
pound, such as Loctite

or equivalent. Follow the
manufacturer’s instructions for curing.
Motor
1.
Install a new O-ring (4) into handle (1) using an
O-ring tool.
2.
Lubricate the 1/16" radius of the outer race (8)
liberally with grease. Install the eighteen steel balls
(9) into the outer race, allowing the grease to hold
the balls in place.
3.
Install the inner race (10). Install the drive shaft with
gear (11).
4.
Install Woodruff key (13) to the drive shaft. Slide
one gear (12) onto the drive shaft by aligning the
keyway in the gear with the Woodruff key. Secure
the gear with the retaining ring (14).
5.
Install the drive pin (16) into the idler shaft (15).
Slide the other gear (12) onto the idler shaft by
aligning the keyway in the gear with the drive pin.
6.
Install the idler shaft assembly into the handle,
meshing the two gears (12).
7.
Install two dowel pins (17) into the handle (1). Install
a new gasket (18).
8.
Assemble motor cap (6) to handle (1), aligning the
scribe marks. Secure with eight cap screws (19).
Using the sequence shown here, torque to 9
Newton-meters (80 inch-pounds).
Clean all parts with an appropriate cleaning solution
and dry them thoroughly. Inspect each component as
described in this section. Replace any component that
shows wear or damage.
1.
Bearings: Insert shaft into bearings. Spin shaft. If
the shaft does not spin smoothly, replace the entire
assembly with bearings already pressed in.
2.
Motor Cap and Case: Inspect mating surfaces, bores,
oil passageways, etc. for grooves or nicks. If any
component shows wear or damage, replace the
entire assembly with bearings already pressed in.
3.
Drive Shaft and Idler Shaft: Inspect all surfaces,
including gear teeth, for grooves or nicks.
4.
Outer Race, Inner Race and Steel Balls: Insert balls
into outer race. Assemble inner race and insert
shaft. Spin shaft. If the shaft does not spin
smoothly, replace the inner race and steel balls. If
the outer race shows wear or damage, replace the
entire handle with the outer race already pressed in.
5.
Planet Gear with Needle Bearings: Insert dowel pin
(43) into bearing. While holding the dowel between
a thumb and forefinger, roll the gear in the palm of
your other hand. If either gear does not spin
smoothly, replace both gears with bearings already
pressed in.
6.
Inspect all other disassembled components for
cracks, grooves or nicks.
