a) Place the pump housing face down as shown in Fig-

ure 17.

b) Install the new inner stationary seal o-rings into the 

grooves in the seal housing. 

c) Install the new seal o-rings into the o-ring seal hous-

ings. Do not lubricate the o-rings before installing.

d) Install one of the seal housings onto the pump hous-

ing with the flat side toward the middle as shown. 

e) Insert the seal housing screws through the holes in 

the o-ring seal housing and thread into the pump 
housing. Tighten with the appropriate Allen wrench. 

f) Double o-ring seals only, place the new small seal 

housing o-ring into the groove on the secured o-ring 
seal housing. 

g) Install the other o-ring seal housing onto the pump       
housing by repeating instructions e and f.
h) Lubricate the pump shafts with a food grade lubricant 

compatible with the o-rings. Lubricate the shafts where the o-rings will slide. 

i) You are now ready to install the pump housing onto the gearbox. Install the pump housing while 

slowly rotating the shaft.

Note: Any debris between the gearbox and housing will affect the gap. Make sure the gearbox front face 
and pump housing surfaces are clean. 
a)  Carefully slide the pump housing over the pump shafts and onto the gearbox. Make sure that the 

housing is positioned so that the smaller pin slides into the smaller bushing on the gearbox and the 
larger pin slides into the larger bushing. The long housing studs will help to align the pump housing 
in the proper position. 

b) Secure the pump housing with the hex head housing bolts and tighten with the appropriate wrench. 

On the FKL 5 use six 18mm long bushings over the six housing studs and install the cover nuts to 
hold the housing in place during assembly.

c) Install the new rotor o-rings into the groove on the back of the rotor hub. 
d) Now slide the rotor with one dot on the drive shaft and the rotor with two dots on the idle shaft. 

Note: when sliding the rotor onto the shaft, the o-ring should be facing the pump housing.
