SECTION 4 
SERVICE PROCEDURES 

 
 
This  section  describes  various  assembly 
and  disassembly  procedures  necessary  for 
pump  servicing  or  parts  replacement.    The 
General  Requirements  and  Safety  Rules 
section  is  a  reminder  for  the  maintenance 
personnel of the critical importance of safety 
rules  and  precautions  while  working  on  the 
pump.    Notes  on  dangers  and  notices 
specifically  related  to  service  procedures 
are repeated and placed in this section also.   
 
The  pump  consists  of  two  major  modules: 
(1)  the  fluid  end  and  (2)  the  combination 
power  end  and  gear  reduction  unit.  (See 
SECTION  2)  The  description  of  service 
procedures  follows  the  modular  concept. 
Due  to  many  expendable  parts,  fluid  end 
servicing  is  rather  common  in  the  field  and 
is therefore presented in the very beginning 
followed  by  the  power  end  /  gear  reduction 
unit servicing procedures. 
 
General Requirements and Safety Rules 
 

 

 

DANGER 

 

Before any attempt to work on pumps 
is 

made, 

all 

safety 

rules 

and 

precautions described in this manual 
must be read and clearly understood. 
 

 
 

 

DANGER 

 

Only  qualified  and  specially  trained 
personnel  should be allowed to work 
on this pump. 
 
 

 

 

DANGER 

 

Proper capacity hoist and lifting 
devices should be used while 

working on pump. 

FLUID END SERVICE 
 
This discussion starts with the description of 
steps necessary for removal and installation 
of  the  fluid cylinder assembly and proceeds 
to  the  removal  and  replacement  of 
expendable  parts  such  as  valves,  valve 
seats, and packing. 
 
Fluid End Removal and Installation 
 
1. 

Disconnect  suction  manifold  from  unit 
piping  and  discharge  lines  at  the 
discharge  flanges  on  the  fluid  end, 
plunger  lubrication  lines,  and  also  any 
accessories  such  as  stroke  counters, 
pressure gages, etc. from the fluid end 

 
2. 

Open any cover or covers on the top of 
the plunger-clamp area and disconnect 
the  plungers  from  the  extension  rods 
by removing plunger clamps. 

 
3. 

Move  the  plungers  inside  the  fluid 
cylinder  as  far  as  possible,  taking  care 
not to damage the plunger or pony rod. 

 
4. 

Connect  hoist  to  the  fluid  end  and 
tighten  the  slings  until  they  are  snug 
only. Make sure that hoisting slings are 
not  too  tight,  because  that  may  put  a 
strain on the stay-rods and damage the 
threads when the cylinder is removed. 

 
5. 

Remove  all  twenty  (20)  1-3/4"  Hvy. 
Hex.  Nuts  from  the  fluid end mounting 
flange using a hydraulic tensioning tool 
or  hammer  wrench.  (A  hydraulic  or 
manual 

torque 

wrench 

is 

recommended 

for 

proper 

re-

installation). 

 
6. 

Pull 

the 

fluid 

end 

assembly 

horizontally,  straight  away  from  the 
power  end  until  it  is  completely  free 
from the stay rods. 

 
7. 

Move  the  fluid  end  to  the  service  area 
for changing valves or other service.
