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.
As described on the following pages, this manual
will alert personnel to known procedures which re-
quire special attention, to those which could dam-
age equipment, and to those which could be dan-
gerous to personnel. However, this manual cannot
possibly anticipate and provide detailed precau-
tions for every situation that might occur during
maintenance of the unit. Therefore, it is the respon-
sibility of the owner/maintenance personnel to en-
sure that only safe, established maintenance pro-
cedures are used, and that any procedures not ad-
dressed in this manual are performed only after es-
tablishing that neither personal safety nor pump in-
tegrity are compromised by such practices.
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. Suction and dis-
charge hoses and piping must be re-
moved from the pump before lifting.
Back Cover Removal
(Figure 2)
Before attempting to service the pump, remove the
pump casing drain plug (54) and drain the pump.
Clean and reinstall the drain plug. The wear plate
(51) and check valve (73) are easily accessible and
may be serviced by removing the back cover as-
sembly (56).
Remove the cover clamp screw (61) and clamp bar
(62) securing the back cover. Pull the back cover
and assembled wear plate from the pump casing
(1). Inspect the back cover gasket (55) and replace
it if damaged or worn.
Inspect the wear plate and replace it if badly scored
or worn. To remove the wear plate, disengage the
hardware (52 and 53).
Suction Check Valve Removal
(Figure 2)
If the check valve assembly (73) is to be serviced,
reach through the back cover opening and hold
the assembly in place while removing the check
