4. Push the displacement rod (103) out through the
bottom of the cylinder (101).
5. Remove the bearing (112), packing (113),
packing housing (114), and o-ring (110).
6. Remove the retaining pin (106) and o-rings
(105). Pull the connecting rod (104) from the
displacement rod (103). Remove the ball (107),
piston ring (108), seal (111), and o-rings (109,
110).
7. Clean and inspect all parts. Refer to
Cleaning the Air Motor, page 3
. Replace the
parts as necessary.
Reassemble After Cleaning
Note: Any damaged parts must be replaced.
Note: Lubricate the o-rings, throat packings, and
piston seals with appropriate waterproof sanitary
lubricant.
1. Wash all pump parts with an appropriate cleaning
solution at the cleaning product manufacturer’s
recommended temperature and concentration.
2. Rinse all pump parts again with water and allow
them to dry.
3. Inspect all pump parts and reclean if needed.
4. Immerse all pump parts in an appropriate
sanitizer before assembly. Take the pump parts
out of the sanitizer one-by-one as needed.
5. Install the v-block packing (113) and bearing
(112) in the packing housing (114). The lips of
the packing must face down into the housing,
and the lip of the bearing must face up. Install the
o-ring (110) on the outside of the housing. Place
the packing housing in the top of the cylinder.
6. Install the o-rings (109, 110) on the piston seal
(111). Install the seal on the piston valve housing
at the top of the connecting rod (104). Install the
piston ring (108).
7. Place the ball (107) on the seat of the housing
(104). Install the displacement rod (103) over the
top of the connecting rod so the holes in both
parts align. Secure with the retaining pin (106)
and o-rings (105).
8. Slide the displacement rod up through the
cylinder so it protrudes from the packing housing
(114).
9. Slide the valve stop (117) and bearing (118) onto
the connecting rod (104). Install the packings
(120) in the poppet (119) and slide onto the
priming piston rod.
10. Install the gasket (116) on the inlet valve housing
(102). Secure the housing to the cylinder (101)
with the clamp (115). Slide the priming piston
(121) onto the rod. Install the retaining pin (122)
in the connecting rod (104).
