NT 1010-G00 05.13 CC8-65 EP Pump e 2/8
1. PRESENTATION
2. OVERALL DIMENSIONS
The pump has only one direction ; depending on that of the power take-off, it will be driven by one end of the shaft or the other.
In both cases, the position of the intake and discharge ports as well as that of the bypass remain fixed. It allows, nonetheless,
rotation in the reverse direction at low speed and pressure to drain the lines.

5. ASSEMBLY / DISMANTLING
Before any disassembly, make sure that the pump has been
drained. In addition, before opening the pump, the end-plate
heating system must be disconnected.
5.1 Necessary tools
• Flat spanners 13 - 17 - 22
• Tubular socket spanner 17
• Opening circlip pliers
• Screwdriver
5.2 Opening up of the pump at non-drive side
Loosen the screws 723 and remove the end-cover 705.
Remove the circlips 537.
Carefully clean the shaft end to remove any traces of
paint. oxidation, burrs, etc...
Loosen the 4 screws 410.
Loosen the 2 screws 411 fitted with their nuts, and place
them in the 2 tapped holes T.
Screw these 2 bolts simultaneously so that the cover is
progressively uncoupled from the axle. When the cover is
free on the shaft, withdraw it manually while supporting it.
5.3 Opening of the pump at drive side
Uncouple the pump by removing the cardan or the cou-
pling sleeve and eventually the reductor.
Remove the key, carefully clean the shaft end then pro-
ceed in an identical manner to the disassembly at non-
drive side.
5.4 Reassembly
Fit the end-cover 705 on the cover using the screws 723.
Slightly lubricate the shaft 501.
In the re-assembly operation, make sure the O-ring 403 is
positioned accurately. Check it and change it if necessary.
Position the cover on the shaft and advance it as far as
possible by hand positionning the drive spigots of the
shaft O-ring opposite the slots of the rotor as well as pin
402 in the housing. Don't forget the O-ring 403. The end-
plate on the discharge side cannot be interchanged with
the end-plate on the intake side.
The operator should remain nearby the equipment throughout
the use to ensure the proper functioning of the system.
4. USE

Finish fitting the end-plate by gradually screwing the 2
nuts 412 onto the 2 screws 411.
Make sure that the end-plate lies on the center line while
it is being screwed down.
When the end-plate is installed, remove screws 411 fitted
with their nuts 412 and screw them into the 2 bosses.
Put screws 410 back in place.
Remove the end-cover 705, fit the circlips 537 and refit
the cover 705, checking seals 707 and 714.
Free the shaft line by a slight blow with a mallet at its
ends and makes sure that the pump turns freely by
hand.
Screws 411, which are longer, are to be screwed back
into the holes in the end-plate having 2 bosses.
5.5 To change the vanes
Open the pump on the drive side.
Remove from the remaining end-plate the 4 screws 410,
the 2 screws 411 and take out the vanes 317 as well as
the 3 pushrods 318. Check the vanes and pushrods for
wear. (see § MAINTENANCE).
In case of abnormal wear, check the surface of the body
and the faces of the end-plate. Refit the pushrods,
making the holes in the rotor and the shaft coincide and
making sure that the packing drive spigots are facing the
notches in the rotor (see § REASSEMBLY).
Refit the vanes (new if necessary), orienting them cor-
rectly.
Reinstall the end-plate/shaft/rotor assembly, making
sure that the end-plate seal is in the right position. Check
it and replace it if necessary.
Complete reassembly of the pump by reinstalling the
other end-plate and check that it can be turned easily by
hand.
5.6 Changing of single-piece packing (item 630)
DISMANTLING
Open the pump and lay the end-plate on its machined
side, being careful not to damage the 2 packing drive
spigots as well as the positioning pin (in the case of
assembly with speed-reduction gearing, remove bolts
724 from the reduction gear side plate 706 and take off
the shim 710).
Remove the parts.
Take out packing 630 by pulling on it with the fingers
inside its bore.
REASSEMBLY
Refit the packing (new if necessary).
Reassemble all the parts in reverse order with respect to
disassembly (do not forget shim 710 when assembling
with a speed reducer).
In this operation, make sure that gaskets 605 and 613
are good.
Refit the end-plate (see § OPENING PUMP ON SIDE
OPPOSITE DRIVE SIDE).

5.7 Dismantling and reassembly of the bypass
for visit
DISMANTLING
Set the bypass to the minimum pressure by fully unscre-
wing nut 834.
Note the number of turns made when unscrewing it so
as to be able to set the bypass to the same pressure
when reassembling.
Remove the 3 screws 856 from the bypass cap.
Take out the spring 824.
Remove the poppet 823 by pulling on its cylindrical sec-
tion with the fingers.
Check the bypass.
Clean all parts prior to reassembly.
REASSEMBLY
Reassemble in reverse order with respect to disassembly.
Set the bypass to the pressure desired by retightening
nut 834 the number of turns note when disassembling.
Tighten down lock nut 835.

Aside from greasing the bearings periodically with high-
temperature grease (for ex. ENERGREASE HTG2-BP), it is
necessary to check, every 500 hours :
• condition of the vanes :
Original height : . . . . . h = 38 mm
replace them if :. . . . . h < 36 mm
• condition of the pushrods :
Original height : . . . . . h = 79 mm
replace them if :. . . . . h < 78 mm
• surface condition of the body and end-plates ; if there
is extensive grooving, an overhaul is required.
• condition of the bypass. Clean it if dirty.
