11)  Install sensor disc [2900] (if it is located on the 

end of the shaft) and outer retaining plate (if 
applicable).  

12)  Apply an even film of Loctite Gasket Eliminator 

504 (or equivalent) to parting surface of bottom 
halves of bearing housings. Note cure time on 
the container.  

13)  Set top halves of bearing housing on bottom 

halves. Install cap screws in flanges and evenly 
tighten.  

14)  Wipe off any excess gasket sealant.  
15)  Temporarily install end cover [3266] without 

sealant. Evenly tighten cap screws [6570.7].  

16)  Install dial indicator to read on end of shaft.  
17)  Firmly push shaft in one direction until it stops 

solidly and set dial indicator to zero.  

 

 lf in doubt about how to machine the end 

cover [3266], contact your nearest Flowserve Sales 
Office (See section 6.2.1).  
 
18)  Push shaft in opposite direction until it stops 

solidly. Read dial indicator. Shaft movement 
should be within the thrust bearing axial 
clearance specified under section 10.3. If a 
minute adjustment is necessary, make certain 
that bearing, seal units, and internal assembly 
parts are correctly sized and assembled, then 
machine either:  
a)   End cover [3266] surface that abuts thrust 

bearing [3032] if low limit is exceeded,  

b)   End cover [3266] surface that abuts bearing 

housing [3230], if high limit is exceeded.  

 
19)  If pump is equipped with mechanical seal units, 

tighten shaft sleeve collars (or nuts) and secure 
them with set-screws. Unlock shaft sleeve from 
seal plates, see mechanical seal (section 6.9.4). 

20)  Position deflector rings [2540] or Inproseal rotors 

per dimension given in section 10.3.  

21)  Verify that the rotor turns easily and smoothly by 

rotating shaft [2100].  

22)  To secure the cartridge assembly, install the 

tension flange in

 

place of the pump half-coupling 

on the shaft and secure it with the coupling nut 
(7411), see 

Figure 6-5

: Typical

 

Tension Flange 

Arrangement. Some cartridge assembly may 
use coupling nut [7411] and pump half coupling 
with the tension flange, then install the tension 
flange between the pump half coupling and 
bearing housing. 

23)  Remove thrust bearing housing end cover 

(3266). Apply an even film of sealant to parting 
surface of end cover that abuts bearing housing. 
Install cover with stationary oil baffle or Inproseal 
stator (if installed), and evenly tighten cap 
screws. 

6.9.6   Main Lube Oil Pump Installation  

These instructions provide for installation of a 
lubricating oil (lube oil) pump that is flange-mounted 
to the outboard bearing housing end cover [3266] for 
direct and axial coupling of its shaft with the pump 
shaft. If your pump is not equipped with such a lube 
oil pump, please disregard this section.  

6.9.6.1  Installing Half-Couplings (Lube Oil Pump) 

To install half-couplings, proceed as follows:  
1)   Verify that vibration sensor disc [2900] is 

installed, if applicable (see assembly drawing), 
also verify that bearing end cover [3266] is not 
installed (see section 6.9.5).  

2)   Install half-coupling key in shaft of vibration 

sensor disc [2900] or in end of pump shaft, 
whichever is applicable (see assembly drawing), 
slide half-coupling completely onto key, and fix 
half-coupling to shaft of disc or end of pump 
shaft, whichever is applicable, with set screw.  

3)   Install spider in half-coupling on shaft of 

vibration sensor disc [2900] or end of pump 
shaft, whichever is applicable (see assembly 
drawing).  

4)   Install half-coupling key in shaft of lube oil pump, 

slide half-coupling onto key, allowing coupling 
face to extend past end of lube oil pump shaft. 
Do not install set screw.  

5)   Solidly butt together flanges of lube oil pump 

and bearing end cover [3266]; then withdraw 
lube oil pump. Measure 1.5 mm (0.06 in.) from 
hub of half-coupling toward lube oil pump case 
and mark distance on shaft; then move half-
coupling hub to mark and secure it to shaft with 
set screw. There shall be a total gap of 1.5 mm 
(0.06 in.) between spider and half-couplings.  

6)   Remove end cover [3266]. Apply an even film of 

sealant to parting surface of end cover [3266] 
that abuts bearing housing [3230]. Install cover 
with stationary oil baffle or Inproseal stator (if 
installed), and evenly tighten cap screws.  

7)   Wipe off any excess sealant.  

6.9.6.2  Installing Lube Oil Pump  

To install the lube oil pump, proceed as follows:  
1)   Ensure:  

a)   That lube oil pump has been inspected and 

assembled for operation as given by 
manufacturer's instructions in section 10  

b)   That half-couplings are free of burrs and 

gouges  

c)   That half-couplings are installed and held 

firmly in place by set-screws (see section 
6.9.6.1 above).  

2)   Install spider in half-coupling on shaft of 

vibration sensor disc [2900] or end of pump
