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.
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 remove the key to ensure
that it will remain inoperative. Close all valves in the
suction and discharge 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
remove the key to ensure that the
pump will remain inoperative.
3. Allow the pump to cool if over-
heated.
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 (52) and drain the pump.
Clean and reinstall the drain plug. The wear plate
(49) and check valve (71) are easily accessible and
may be serviced by removing the back cover as-
sembly (54).
Remove the cover clamp screw (59) and clamp bar
(60) securing the back cover . Pull the back cover
and assembled wear plate from the pump casing
(1). Inspect the back cover gasket (53) and replace
it if damaged or worn.
Inspect the wear plate and replace it if badly scored
and worn. To remove the wear plate, disengage the
hardware (50 and 51).
Suction Check Valve Removal
(Figure 2)
If the check valve assembly (71) is to be serviced,
reach through the back cover opening and hold
the assembly in place while removing the check
valve pin (77). Slide the assembly from the check
valve seat (63) and remove it from the pump.
