Use either of the following procedures to properly adjust the 

end clearance when replacing gaskets:

PROCEDURE A:
With balance plate in position, slide rotor and shaft into 

casing  Insert a feeler gage of the proper thickness into the 

port and between two rotor teeth 

10).  Install one 0 015” and one 0 007” gasket onto head   

With the idler on the idler pin, place the head into the pump 

casing   With the capscrews tight, the feeler gage should fit 

snugly, otherwise gaskets should be added or removed until 

the proper clearance is attained 

The pump is designed to take fluid from the discharge side 

of the pump and channel it down the idler pin into the shaft 

and out into the canister through the capscrew which secures 

the inner magnet  The fluid is returned through a hole in 

the casing back to the suction side of the pump  There are 

generally three parts which may need replacing or adjusting 

to change rotation 
HEAD & PIN – Hole should be from the discharge side of 

head to the pin and a pipe plug is placed in the tapped hole 

on the suction side of the head  To change rotation, move the 

plug to the opposite side of the head 
BALANCE PLATE – If the plate is separate from the bracket 

and looks like the Style A in 

Figure 22, it can be reversed  The 

groove should connect the discharge port to the bushing bore  

If rotation is changed, the plate is flipped over (not rotated) 

and the groove would not be visible but will still function 

properly  If the plate is like Style B, it is 

NOT reversible and a 

new plate will be required 
BRACKET – The bracket will have two holes drilled through 

and tapped on one side  The discharge side of the bracket 

should feature a pipe plug with a hole drilled through it  To 

change rotation simply move this pipe plug to the other hole 
Contact your local Viking distributor or the factory to determine 

which parts are required 

PROCEDURE B:
If the pump is in line and the ports are not accessible, 

remove the head and gaskets  Put the head back on (without 

gaskets) and measure the gap as shown  

page 10). After determining the gap between the head and 

casing, select a combination of gaskets with approximately 

25% more total thickness than the gap plus the required end 

clearance  Note that the gaskets will compress when head is 

tightened down   Remove the head, install all gaskets then 

replace the head   Tighten the head capscrews and check 

the pump clearance by making sure  the pump turns freely 

by hand 
Since the pump shaft is concealed, it is best to work up the 

proper end clearance because it is difficult to determine when 

there is to much end clearance with this approach
