1. First remove the tie rod, washer and nut
assembly (409, 410, 411, 412), cap screws
(114) and washers (115) to remove the lower
coupler, bucket, attachments and/or other
assemblies.
2. Next remove the port plugs (106) and
drain the oil. Inspect the oil for signs of
contamination, i.e. water, metal shavings.
3. During the end cap removal process, begin
with removing the set screws (113) that
cover the end cap lock pins (109). Using
a 4 mm drill bit, drill a hole in the center of
each lock pin to a depth of approximately
9.5 mm. Remove the lock pins using a screw
extracting tool. Insert two appropriately
sized screws and service pins in the grease
ports. Unthread the end cap (4) by turning it
counterclockwise using a pry bar. Remove the
end cap and set aside
for inspection.
4. Rotate the shaft (2) and piston sleeve (3) so
both components are ush with the ring gear
inside the housing (1). Do not remove the

Gently tap the end of the shaft with a plastic
mallet and mandrel if needed.
7. As in Step 6 above, before removing the
piston sleeve (3), mark the housing (1) ring
gear in relation to the piston sleeve outside
diameter gear with a marker as seen in the
photo below. Be sure to gently push the piston
sleeve (3) out of the housing (1) until the gear
teeth just come out of engagement with the
housing gear teeth. Then remove the piston
sleeve (3). Use a plastic mallet and mandrel
if necessary.Avoid scratching or denting the
inside of the housing bore.

washers from the end cap (4), shaft (2), piston
sleeve (3) and housing (1). Note their order

gear timing marks can be located in Step 5.
5. Locate the timing marks on the piston sleeve
(3) gearing and shaft (2). Every PowerTilt has
two sets of small punched timing marks that
indicate timing between the gear sets. One
set indicates the timing between the shaft (2)
and the piston sleeve (3) as seen in the photo
above (the shaft timing marks may be located
in the root or “V” of the gearing). The second
set indicates timing between the piston sleeve
and the housing (1) as seen in the photo
below.
6. Prior to removing the shaft (2), use a felt
marker to highlight the punched timing marks
between the shaft and piston sleeve (3) as
seen in the photo below to simplify timing when
the PowerTilt is reassembled. Rotate the shaft
(2) counterclockwise until it disengages from

5. Insert the shaft (2) into the piston sleeve (3),
aligning the timing marks of the shaft with
the piston sleeve. Once the timing marks
are veried, rotate the shaft inward until the
pressure seal (205) contacts the housing (1).
Then tap gently to compress the seal and
rotate the shaft into the housing.
6. Thread the end cap (4) onto the shaft (2).
Using a pry bar, tighten the end cap until the
lock pin (109) holes align. Then insert the lock
pins (109) into the holes with the dimple side
up. Using a punch, tap the lock pins to the
bottom of the hole. Insert the set screws (113)
over the lock pins and tighten to 2.8 Nm. Install
the port plugs (106).
1. Before installation, coat the seals and
machined surfaces with a high quality
hydraulic oil.
2. Coat the end cap (4) threads and both
sides of the thrust washers (304) with
lithium grease.
3. Install all the seals, bearings and thrust
washers on the end cap (4), piston sleeve
(3) shaft (2) and housing (1). Refer to the
Assembly Drawing on Page 2 and PT-4.5
Exploded View on Page 3 for correct locations
and orientations.
4. Carefully insert the piston sleeve (3) into the
housing (1) until it contacts the housing ring
gear. Rotate the piston sleeve until the timing
marks applied to the piston and housing
during the disassembly process align. Using
a plastic mallet or mandrel, tap the piston into
the housing until the gear teeth contact.
Replace all seals, bearings and
thrust washers (304) as required.
NOTICE
As the shaft is installed, be careful not
to disengage the piston sleeve and
housing gearing.

Post Assembly
Greasing and Testing
If the equipment is available, the PowerTilt
should be tested on a hydraulic test bench. The
breakaway pressure — the pressure at which the
shaft begins to rotate — should be approximately
28 bar. Cycle the actuator at least 25 times at 210
bar pressure.
Testing for internal leakage
Connect hydraulic lines to the housing ports.
Bleed all air from the PowerTilt. Rotate the shaft
to the end of rotation at 210 bar and maintain
pressure. Remove the hydraulic line from the
non-pressurized side. Continuous oil ow from
the open housing port indicates internal leakage
across the piston or cross port relief valve.
Replace the line and rotate the shaft to the end
of rotation in the opposite direction. Repeat the
test procedure outlined above for the other port. If
there is an internal leak, disassemble, inspect and
repair.
Greasing
Testing
After the actuator is assembled but before it is
put into service, the thrust washer area must be
packed with Lithium grease.
1. There are two grease ports located on both
the shaft ange and the end cap. They are
plugged with cap screws (113) or set screws.
Remove the grease port screws from the shaft
ange and end cap. (See exploded view on
page 4)
If a hydraulic test bench is not
available, the actuator can be
rotated by hand, open the pressure
ports and use a pry bar with cap
screws inserted into the shaft
ange to turn the shaft in the
desired direction.
2. Insert the tip of a grease gun into one port
and apply grease to the shaft ange. Continue
applying until grease ows from the opposite
port. Cycle the actuator ve times and apply
grease again. Repeat this process on the end
cap. Insert the cap screws into the grease
ports and tighten to 25 in-lbs. (2.8 Nm).

Maintenance
1. Grease the thrust washers at the two grease
ttings with a high quality Lithium-based
grease. Apply grease until clean grease ows
from the grease reliefs. Severe operating
conditions such as abrasive dust or prolonged
submersion in water may require more
frequent grease applications.
2. Make sure the grease reliefs are functioning
properly. Open or replace non-functioning
grease reliefs immediately.
NOTICE
Never replace the grease relief
valves with grease ttings or
plugs.
NOTICE
Do not operate the PowerTilt if the
grease reliefs are not functioning.
1. Check shaft end play. When the end play
exceeds 0.38 mm, the end cap must be
tightened.
2. Retighten torque foot M10 bolts (114) to 68
Nm (50 ft-lbs) and tie rod bolt nut (411) to 920
