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 illustrations (see Figures 1 through 4) 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 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 John Deere 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.
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi­
cient capacity and that they are posi­
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Suction and dis­
charge hoses and piping must be re­
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.
