Design and function
F1 is a piston pump with spherical pistons (1) including
piston rings (2). The pistons are working at the angle of
40° to the shaft (3). When the shaft rotates, the pistons
move up and down in the cylinder barrel (4), forcing the
oil to pass from the inlet port to the onlet in the end cap
(5). A ring gear (6) connects the cylinder barrel to the
drive shaft, causing these to rotate at the same speed.
A barrel support (7) with a spring presses the cylinder bar-
rel against the end cap. An internal connection from the
housing to the suction port eliminates a separate drain
line to the tank. F1 is provided with shaft and connection
flange that fits direct to PTO´s with ZF standard.

2.
Turn the end cap half a revolution.
Change of direction of rotation, which means turning the
end cap, is carried out as follows:
Fasten the pump so that the connections point upwards.
3.
Fasten the end cap.
Torques to be used:
F1-20, -30, -40, -60 60±10 Nm
F1-80, -110 90±10 Nm
Pump fitted for right - hand rotation
Pump fitted for left - hand rotation
Change of Rotation of Direction
The position of the end cap determines the direction of
rotation, and an arrow on the end cap opposite the text
"Rotation" indicates the direction of rotation.
1.
Remove the four screws holding the end cap, ensuring
that the end cap and body do not come apart. The end
cap might be raised a little by the spring of the barrel
support, but do not lift it because the interior parts may
then be displaced, causing a breakdown when the pump
is started.
On the barrel housing the text "Rotation" is found.
An arrow on the end cap opposite this text shows the
direction of rotation of the pump shaft.

Operation Check
Check of Shaft Seal
The pump has two shaft seals - the inner one sealing the
hydraulic oil in the housing, and the outer one the trans-
misson oil when the pump is fitted to a PTO. If any of the
sealrings leak, the oil will come out through an indication
hole.
Indication hole
Note: A heavy leakage can be caused by a worn-out
pump, whereby high pressure oil will come out into the
housing in such large quantities that the sealring might
be damaged. If there is a steady stream of oil from the
indication hole, the pump is probably damaged and will
have to be replaced.
Check that no oil is dripping out of the indication hole,
when the pump is in operation. If there is a leakage from
the sealrings, they must be exchanged, See chapter ”Ex-
change of shaft seals”.
Checking the Flow from the Pump
The flow from the pump can be checked by means of a
test instrument comprising a flowmeter and a relief valve.
Connecton of test instrument
When the pump is running at about 800 - 1400 r.p.m. and
is loaded up to 150 - 200 bar, the flow must not decrease
by more than 10%.
Example:
An F1-40 running at 1225 r.p.m. gives - according to the
flowmeter. - a flow of 48 l/min.
If the pump is loaded, the flow must not decrease by
more than 0,1 x 48 = 4,8 l / min, i.e. the flowmeter should
indicated at least 48 - 4,8 = 43,2 l / min. If the flow drops
below this limit, the pump is worn out and will have to be

Service Procedures
Exchange of shaft seals
A
B
C
D
1.
Pull out the outer seal ring A,e.g. by means of a screw-
driver by piercing the wall of the seal. Take care not to
damage the sealing surface B of the shaft.
2.
Loosen the retaining ring C.
3.
Pull out the inner seal ring D in the same way as the outer
one.
4.
Check that the sealing surface of the shaft is undamaged.
If damaged, the pump has to be taken apart and the slewe
has to be replaced.
5.
Push on the new inner sealring.
6.
Fit the retaining ring. See to it, that the opening of the
retaining ring is placed at the indication hole, which will
otherwise be blocked.
7.
Fill out the space between retaining ring and shaft with
heat - resistant grease.
8.
Fit the new outer seal ring.

2.
Loosen the screws joining the bearing housing and the
barrel housing, and remove the barrel housing.
3.
Remove the cylinder barrel.
4.
Mark piston and corresponding ball socket to enable cor-
rect location when reassembling.
5.

parallelly to the drive shaft.
6.
Remove barrel support.

7.
Place the bearing housing on a support, and knock cau-
tiously on the shaft until it can be removed.
Checking and Replacement
Clean all parts when the pump has been disassembled.
Check carefully for wear and damage. Replace all gaskets
and seal rings.
If the oil flow from the F1 pump is less than normal, the
following parts are likely to be worn:
- The surface facing the cylinder barrel on the
end cap.
- The end surface of the cylinder barrel.
- The piston rings
Scores and marks on these parts will always decrease the
performance of the pump. Always replace them by new
The laminated piston rings should always be replaced at
a major overhaul (due to fatigue), and if the play between
piston and new rings is more than 0,2 mm also the piston
should be replaced.
Remove the bearing from the shaft
Max 0,2 mm

Assembly
1.
Remove the plug from the barrel housing.
2.

sembly into the housing.
4.
Fit the barrel support and the pistons into their respective
ball cups.
5.
Find the marked tooth on the shaft.
6.
Find the marked tooth space on the cylinder barrel.
7.

9.
Slip the barrel housing over the cylinder barrel. Fit and
tighten the screws.
10.
Check through the inspection hole that the two marks are
opposite each other. If not, correct this.
11.
The backlash of the gear must be 0,05 - 0,30 mm . This
play can be checked through the inspection hole, with a
feeler guage.
The number of gaskets between end cap and bearing
housing determines the backlash.
When assembling, use the same number of gaskets as
found at the disassembly. If the number is unknown, try
with 2 gaskets.
12.
Fit the end cap so as to enable the correct direction of
rotation. Tightin the screws lightly. Check that there is a
backlash. If the backlash is unsufficient, fit more gaskets.
Tightening torques:
F1-20 / 30 / 40 / 60 35-45 Nm
F1-80 /110 70-80 Nm
13.
Fit the seal washer and the plug at the inspection hole.
