CHANGING ROTATION
1 - Clean the pump externally with care.
2 - Loosen, and remove, the clamp bolts (1).
3 - Coat the sharp edges of the drive shaft (4)
with adhesive tape and smear a layer of cle
-
an grease on the shaft end extension to avo
-
id damaging the lip of the shaft seal when re
-
moving the mounting flange.
4 - Remove the mounting flange (2), taking care
to keep the flange as straight as possible du
-
ring removal. If the flange is stuck, tap aro
-
und the edge with a fibre or rubber mallet in
order to break away from the body. Ensure
that while removing the front mounting flan
-
ge, the drive shaft and other components re
-
main position.
5 - Ease the drive gear (4) up to facilitate removal the front plate (3), taking care that the precision ground
surfaces do not become damaged, and remove the drive gear.
6 - Remove the driven gear (5) without overturning. The rear plate has not to be removed.
7 - Re-locate the driven gear (5) in the position
previously occupied by the drive gear (4)
8 - Re-locate the drive gear (4) in the position
previously occupied by the driven gear (5).
9 - Replace the front plate (3) in its original posi
-
tion.
10 - Remove the grub screw (6) from the moun
-
ting flange (2) and re-locate it in the other
threaded hole in the same flange.
11 - Gently wipe the machined surface of the
mounting flange (2) and the body with a flat
hand stone.
12 - Refit the front mounting flange (2) turned
180° from its original position.
13 - Refit the clamp bolts (1) with the washers
and tighten in a crisscross
pattern to a torque value of 70
±7
Nm
(558 ¸ 682 lbf in).
14 - Check that the pump rotates freely when the
drive shaft (4) is turned by hand. If not a
pressure plate seal may be pinched.
15 - The pump is ready for installation with the original rotation reversed.
Example of changing rotation: from FP30 pump counterclockwise to clockwise
To change rotation of unidirectional pumps is necessary to operate in the following way:
