Models 8752, 8756, and 8757

Operating Procedures 

6

9. Insert the mix inlet fitting into the hole in the base of 

the liquid valve body.

Figure 6-26

10. Secure the pump parts in position by sliding the 

retaining pin through the crossholes located at the 
bottom of the pump cylinder.

Figure 6-27

Note:

The suction line must fit tightly against the 

mix inlet fitting

11. Assemble the flare line and suction line. Assemble 

the weighted end into the suction line. Attach the mix 
suction line to the barbed end of the mix inlet fitting 
and allow the weighted end to hang free.

Figure 6-28

12. Push both nuts back from the flare end and lightly 

lubricate the underside of the plastic flare. This will 
allow the nut to turn freely without twisting the tubing.

13. Attach one end of the flare line to the threaded fitting 

on the lower side of the pump cylinder and allow the 
other end to hang free.

Figure 6-29

14. Secure the air/mix pump. Place the pump collar over 

the pump cylinder. (The crossholes of the pump 
collar should be on top.)

Figure 6-30

15. Align the drive hole in the piston to the ball crank of 

the motor reducer. At the same time, align the 
locating pin hole in the pump cylinder to the locating 
pin on the face plate.

Figure 6-31

Apply the appropriate 
Taylor approved food safe lubricant.
