Design
Series F11 pumps/motors consist of a rotating group contai-
ned in a split housing. Spherical pistons (1) with laminated
piston rings (2) operate at a 40° angle relative to the shaft
(3). Series F11-5 through -78 employ five pistons, series
F11-110 and -150 seven, and series F11-250 nine pistons.
As the shaft turns, the pistons are driven in a reciprocating
movement in the cylinder barrel (4). When the unit is used
as a pump, the oil passes from the inlet port to the cylinder
barrel and is then forced to the outlet port through the pum-
ping action of the pistons.
A spring device (a retaining ring, a leaf spring, or Belleville
washers) maintains the barrel against the valve plate (item 5,
F11-5 through -150) or the end cap (item 7, F11-250). A ring
gear (6) on the shaft meshes with the corresponding teeth of
the barrel (4) so that the cylinder barrel always rotates at the
same speed as the shaft (3). The shaft is supported by two
heavy duty tapered roller bearings (8).

Operational Check
The general condition of the unit can be established by
checking the drain flow. Remove the drain line and keep the
drain port above a suitable container. Run the unit at normal
speed and pressurize the system to 150 - 200 bar .
Measure the drain flow for one minute; if it exceeds the
maximum figures shown below, the unit is worn or damaged
internally and should be replaced or repaired. Also, check
for leakage at the shaft seal and between the bearing and
barrel housings.

Shaft Seal Replacement
Note
The unit does not have to be taken apart.
Remove the retaining ring and the back-up washer (units
designated F11C and F11D might not have a back-up
washer). Without damaging the shaft, punch through the
casing of the seal with a screwdriver and remove the seal.
Check the shaft sealing surface for corrosion and other
damage.
The tool shown in the figure can be used to facilitate the instal-
lation of the new seal. Be careful not to cut the seal on the
shaft key or spline. The chamfer of the back-up washer should
face the seal when installed (concerns N-seal).
Disassembly, Series F11-5 through
-150
Before taking the unit apart, remove the shaft coupling (if
applicable) and thoroughly clean the outside of the unit; seal
the ports with suitable plugs or covers.
1. Remove the four metric cap screws. By utilizing two
screwdrivers, pull the housings apart as shown. Retain
the split shim located between the spacer ring and the
barrel housing.
2. Mark the pistons and the corresponding ball sockets
with a felt-tipped pen.
3. Remove the pistons by pulling them out when in line
with the shaft as shown.

If play indicated in the figure is exceeded then re-
place all piston and ring assemblies in the unit. Never
replace individual worn piston and ring assemblies.
5. Check that the shaft surface in contact with the
shaft seal is in good condition; if grooved, corroded,
or otherwise damaged, the shaft should be replaced.
Note
When lapping the valve plate, up to .002 in. can be
removed. If .002 in. is not sufficient to obtain a flat
surface free of scratches, the part should be repla-
ced.
4. If the bearing cups are loose, the shaft lock nut
should be tightened. Correct bearing pre-load has
been obtained when the spacer ring can be moved
sideways without being loose. Note, for the bigger
units quite a substantial force is required.
Reconditioning and Replacement of
Parts
After disassembly, all parts should be thoroughly clea-
ned in a suitable solvent.
Caution: Follow directions for use of solvent carefully.
Protect your hands and eyes from the solvent.Solvent
may also be inflammable.
If leakage of the F11 unit was too high, the following
parts are generally worn or damaged:
Series F11-5 through -150:
- Valve plate
- Cylinder barrel port surface (facing valve plate)
- Piston rings or piston assy
Series F11-250:
- Bearing plate
- End cap port surface (facing bearing plate)
- Piston rings or piston assy
Max 50%
Old version
Not available
Scratches and wear marks on these parts always affect the
performance of the unit; they should be replaced if scrat-
ched or worn.
1. Shaft seal and o-rings should always be replaced.
2. Replace spherical piston rings that are worn more
than 50 % of the spherical surface as shown. A small
retaining ring pliers will facilitate the removal. When
installing a new piston ring, make sure the spherical
surface coincides with the shape of the piston head.
3. On series F11-5 through -150, the valve plate
surface can be reconditioned by careful lapping.
Series F11-250 end cap port surface can be lapped
but the bearing plate must be replaced if worn.
Production of the spherical piston ring is discontinued.
The old ring and piston has to be replaced by the
laminated version.

Reassembly, Series F11-5 through
-150
All parts should be thoroughly cleaned and lightly lubricated
with hydraulic fluid. Reassembly is carried out in reverse
order of disassembly.
Caution: Follow directions for use of hydraulic fluid carefully.
Protect your hands and eyes from fluid. Fluid may also be
flameable.
The internal drain valve plate G is shown from the back side
of the plate. From the front, when installed, it looks the same
as the M plate.
The following valve plates are available (designation ap-
pears on the nameplate):
M = Bi-directional, motor or pump operation
L = L.H. rotation, pump operation
R = R.H. rotation, pump operation
G = L.H. rotation, internal drain, motor operation
J = R.H. rotation, internal drain, motor operation
H = Bi-directional, motor operation, high pressure
Q = Bi-directional, motor operation, low noise
3. The cylinder barrel retaining ring (does not apply
to Series F11-28 and -58) should be installed as
illustrated below. When installing the barrel in the
housing, the opening of the retaining ring should face
the housing cut-out as shown; the barrel has to be
pushed down to overcome the spring force of the
retaining ring.
Some resistance should be felt when trying to turn
the cylinder barrel by hand; if no resistance is felt, the
retaining ring must be replaced.
Note
Regarding installation of needle bearings in
F11-110 and -150 cylinder barrels, refer to
page 16.
4. Series F11-28 and -58 utilize a leaf spring for bar-
rel hold-down. Install the cylinder barrel on the barrel
post, install the hold-down ring and the leaf spring,
and secure the spring with the locating pin.

5. Install the guide spacer (with new o-rings) to the
barrel housing; make sure one of the cut-outs is in
the position shown, and leave room for the split shim
between the spacer and the housing .
Cut out
6. Install the split shim as illustrated. Make sure the
shim is properly located in the barrel housing recess.
Correct thickness of the shim should result in a gear
backlash of .05 to .20 mm. If any part of the rotating
group has been replaced, it might be necessary to
change to a shim of different thickness; backlash is
checked according to paragraph 12 (page 12).
7. Two teeth on the cylinder barrel and one tooth on
the ring gear are marked to ensure that the pis-
tons are in line with the cylinder bores. Position the
cylinder barrel so that the markings are visible in the
spacer cut-out as shown, this assures correct timing
of the shaft and the cylinder barrel.
8. Locate the marked tooth of the shaft ring gear.
Note
If the shaft assembly has been taken apart, refer to
"Reassembly, Series F11-250" for instructions.
9. Position the shaft/piston assembly over the
housing/barrel assembly as shown, so that the timing
marks of the ring gear and cylinder barrel are lined
up. Locate each piston into the corresponding, previ-
ously marked cylinder bore.
10. If the timing marks don't match as illustrated,
carefully pull the shaft assembly out of mesh with the
ring gear and reposition correctly.
11. Install the bearing housing with a new shaft seal
on the shaft/bearing assembly, being careful not to
cut or otherwise damage the seal. Cross-torque the
cap screws according to specifications on page 3.

2. Install a new tab washer and tighten the lock nut gradu-
ally until the spacer ring between the bearing cups is held
firmly but not tight; you should be able to push the spacer
sideways with your thumbs as shown. Secure the nut with
one of the tabs of the washer.
12. Turn the shaft by hand to assure correct assembly. A
"clicking" noise generated when the shaft is rapidly turned
back and forth reveals that there is backlash between the
ring gear and the cylinder barrel. A "no noise" condition indi-
cates no backlash, and a thicker shim has to be installed.
The correct backlash should be .05 to .20 mm.
Reassembly, Series F11-250
1. If the shaft/bearing assembly has been taken apart,
start the reassembly by installing the ring gear over the
locating dowel pin. Press the cone of the large roller
bearing against the ring gear. Install the large bearing cup,
the spacer ring (note the position of the cut-outs), and the
small bearing cup. Press the small bearing cone onto the
shaft, but only so far that the spacer ring can still be moved
sideways easily.
Note
If the lock nut has been tightened too much as to allow the
spacer to be moved sideways, the bearings have to be
removed from the shaft and the assembly procedure started
over again.
3. Install a new shaft seal and push the shaft assembly into
the bearing housing. Install the pistons in the ball sockets.
4. If a new cylinder barrel is used, install the groove pins
that locate the bearing plate, the internal retaining ring, and
the needle bearings (refer to page 14). Install the barrel
post/bearing assembly in the cylinder barrel. Locate each
piston into the corresponding, previously marked cylinder
bore, and position the cylinder barrel assembly on the ring
gear as shown so that the timing marks are lined up.
5. Install the barrel housing and check through the drain
port that the timing is correct. Cross-torque the cap screws
according to specifications (page 3).
6. Install new o-rings on the end cap; one o-ring is located
in the barrel post bore. Screw tool (without nut and bearing)
into the barrel post, and install the end cap over the tool
spindle against the block housing. Install the split shim as
shown, making sure it is located correctly in the barrel hous-
ing recess.
7. Install the nut/bearing of the tool on the spindle, and , by
tightening on the nut,pull the barrel post partly into the end
cap. Install the three cap screws and tighten according to
specification (page 3).
