Assembly
1. Before installing, clean all parts care-
fully and lubricate all parts using hy-
draulic oil and grease all rubber parts
using Vaseline.
2. Install neutral position springs H in
shaft C and press them into place
(symmetrically extending at both
ends).
3. Insert shaft C into sleeve F, turn the
parts forwards and backwards to allow
the springs to fully extend in the
grooves in the sleeve.
4. Install pin K in the spool.
5. Install bearing B and shaft seal 7 on
the shaft (see image 1).
Place housing A vertically with the
gearwheel side positioned upwards
(see image 2),
6. Carefully guide the spool into housing
A until the shaft seal reaches its cor-
rect position.
7. Place the emergency control ball G,
ball stop I and non-reversing valve
ball J in port P (see image 2).
8. Place intake valve balls D, ball stop E
in port L and port R (see image 2).
9. Install O ring 5 in the housing, ensure
that the O ring is lubricated before in-
stallation.
10. Place plate M in the housing. Twist it
so that the holes correspond (large
should match large, small should
match small).
11. Install the propshaft L in shaft C and
ensure that it aligns with pin K.
12. Install O rings 5 on both sides of gear
wheel N, ensure that the O rings are
lubricated before installation.
13. Align gear wheel N and propshaft L so
that the teeth in the gear wheel corre-
spond to those on the propshaft (see
image 3). Twist the gear wheel so that
the five holes correspond to the large
holes in the housing.
14. Align spacer O inside the gear wheel
N over propshaft L
15. Install the end cover P so that the hole
marked "P" corresponds with port P in
the housing.
16. Install O rings 1 (5x), in the screws Q
(5x).
17. Screw the screws into place Q (5x),
with a torque of 30 ± 3 Nm using a
16mm spanner.
Place the unit vertically with shaft C
placed upwards.
18. Over pressure valve: install the valve
spool, spring, O-ring 2 in the setting
screw and tighten using a 6 mm Allen
key.
19. Choke valves: Install O-rings 4 in the
adjustment plugs and tighten to
3÷4Nm using a 3 mm Allen key.
Install the balls, valve balls and
springs. Install O-rings 2 in the adjust-
ment plugs and tighten using a 6 mm
Allen key.
