Design and function
F2 is a piston pump with spherical pistons (1) inclu-
ding 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
outlet 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
barrel against the end cap. An internal connection
from the housing to the suction port eliminates a se-
parate drain line to the tank. F2 is provided with shaft
and connection ange that ts direct to PTO´s with ZF
standard.

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
transmisson oil when the pump is tted 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 dama-
ged 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 ”Exchange of shaft seals”.
Checking the Flow from the Pump
The ow from the pump can be checked by means of
a test instrument comprising a owmeter and a relief
valve.
Connection of test instrument
When the pump is running at about 800 - 1400 r.p.m.
and is loaded up to 150 - 200 bar, the ow must not
decrease by more than 10%.
Example:
We recommend to test both circuits/ports, as an
example test of port A is described.
An F2-70/35 running at 1200 r.p.m. gives - according
to the owmeter. - a ow of 82 l/min in port A.
If the pump is loaded, the ow must not decrease by
more than 0,1 x 82 = 8,2 l / min, i.e. the owmeter
should indicated at least 82 - 8,2 = 73,8 l / min. If the
ow drops below this limit, the pump is worn out and
have to be replaced / repaired.

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 undama-
ged. 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.

Disassembly
Fasten the pump in a vice.
1.
Loosen the end cap and remove it.
2.
Loosen the screws joining the bearing housing and
the barrel housing, and remove the barrel housing.
3.
Remove the cylinder barrel.

4.
Remove the pistons, which can be lifted out when
held parallelly to the drive shaft.
5.
Remove barrel support.
6.
Carefully knock the shaft end against the table
until the housing comes loose.
7.
Remove the bearing and ring gear from the shaft.

Checking and Replacement
Clean all parts when the pump has been disassemb-
led. Check carefully for wear and damage. Replace all
gaskets and seal rings.
If the oil ow from the F2 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 parts, when necessary.
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.
Max 0,2 mm

Assembly
1.
Remove the plug from the barrel housing.
2.
Fit new seal rings in the bearing housing (see earlier
instructions, page 5).
3.
Fasten the bearing housing in a vice. Mount the shaft
assembly into the housing.
Place an O-ring on the barrel housing.
4.
Fit the barrel support and the pistons into their respec-
tive ball sockets.
5.
Position the cylinder barrel with its mark opposite the
mark of the shaft, and enter the pistons into the cylin-
ders and the barrel support into the centre bore.
9.
Slip the barrel housing over the cylinder barrel. Fit and
tighten the screws. Make sure that the cylinder barrel
with its mark is opposite the mark of the shaft.

The number and thickness of gaskets
determines the backlash
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 and thickness 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 unk-
nown, try with 2 gaskets (1 thick and 1 thin).
10.
Fit the end cap, make sure that the guide pin on the
end cap correspons to the guide hole on the barrel
housing so correct direction of rotation is achieved.
Check through the inspection hole that the two marks
are opposite each other. If not, correct this.
Tightin the screws lightly. Check that there is a back-
lash. If the backlash is unsufcient, t more gaskets.
Tightening torques:
F2-All sizes 90±10 Nm
12.
Fit the plug at the inspection hole (20-35 Nm).
Test the pump in the test stand. Always ll the
pump with oil before start up.
