a freezer prior to assembly to assist insertion.
Figure 4-1

Insert suction sleeve, check ball and O-ring carefully into check bore.
NOTE: The Suction Sleeves have a shoulder diameter larger than their body
diameter. Additionally the Suction Sleeves when compared to the Discharge
Sleeves have a thicker top region which acts as a robust contact point for the O-
rings.

Repeat insertion process with the discharge sleeve, check ball and O-ring.

Repeat process for second check bore.

Replace check cap seals and tighten check bore caps to 35in-lbs.

Install shaft seals into shaft bore grooves.

Thread shaft into push plate until engagement with the shaft shoulder is
achieved. Additionally apply a ¼” turn to ensure proper installation.

Insert shaft through shaft bore using shaft bullet as shown (This prevents
damage to the TFE shaft seals and prevents dislodgement of shaft seals).
