V14 Displacement limiter
Max and min displacement limiter consists of a socket
head cap screw and a displacement spacer or spacers,
see fig. 1. Suitable screw lengths for a particular max
or min displacement range are shown in the table 1 be-

low. What length the max or min displacement spacer
should have to obtain a chosen displacement is shown
on page 5 and 6. The displacement spacers are availa-
ble in five different lengths: 1; 1,5; 2; 5 and 10 mm. To
obtain the right displacement, the spacers can be com-
bined with each other’s. The thinnest spacer has to be
mounted closest to the setting piston, and the others in
increasing length order.

Displacement spacer changing procedure:
1.
Disassemble the max or min end cover by loosen
the four screws for the chosen cover.
2.
Loosen the socket head cap screw from setting piston.
Note! This must be done when the control module is
assembled on the motor, otherwise the
feedback arm could be damaged.
3.
Choose spacer (s) to obtain right displacement, see page 5 and 6, and place them
on the socket head cap screw.
4.
Tighten the socket head cap screw in the setting piston. The tightening torque have
to be 105 ± 20 Nm.
5.
Assembly the end cover. The tightening torque have to be 60 ± 10 Nm for the four
screws.
