PUMP AND SEAL DISASSEMBLY
AND REASSEMBLY
Review all SAFETY information in Section A.
Follow the instructions on all tags, label and de-
cals attached to the pump.
This pump requires little service due to its rugged,
minimum-maintenance design. However, if it be-
comes necessary to inspect or replace the wearing
parts, follow these instructions which are keyed to
the sectional views (see Figures 1, 2 and 3) and the
accompanying parts lists.
This manual will alert personnel to known proce-
dures which require special attention, to those
which could damage equipment, and to those
which could be dangerous to personnel. However,
this manual cannot possibly anticipate and provide
detailed precautions for every situation that might
occur during maintenance of the unit. Therefore, it
is the responsibility of the owner/maintenance per-
sonnel to ensure that only safe, established main-
tenance procedures are used, and that any proce-
dures not addressed in this manual are performed
only after establishing that neither personal safety
nor pump integrity are compromised by such prac-
tices.
Most service functions, such as wear plate, impel-
ler, and seal replacement, may be performed by
draining the pump and removing the back cover
assembly. However, the following instructions as-
sume complete disassembly is required.
Before attempting to service the pump, switch off
the engine ignition and disconnect the positive bat-
tery cable to ensure that the pump will remain inop-
erative. Close all valves in the suction and dis-
charge lines.
For engine disassembly and repair, consult the lit-
erature supplied with the engine, or contact your
local Deutz engine representative.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man-
ual.
2. Switch off the engine ignition and
disconnect the positive battery
cable to ensure that the pump will
remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature before
opening any covers, plates, or
plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau-
tiously.
7. Drain the pump.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment. The bail is intended
for use in lifting the pump assembly
only. Suction and discharge hoses and
piping must be removed from the pump
before lifting.
Back Cover Removal
(Figure 2)
Before attempting to service the pump, remove the
pump casing drain plug (42) and drain the pump.
Clean and reinstall the drain plug. The wear plate
(41) and check valve (57) are easily accessible and
may be serviced by removing the back cover as-
sembly (49).
Remove the cover clamp screw (46) and clamp bar
(45) securing the back cover. Pull the back cover
and assembled wear plate from the pump casing.
Inspect the back cover gasket (54) and replace it if
damaged or worn.
