Typical Example
Use suitable lifting device to lift the heat exchanger. The weight of the heat exchanger is approximately 92 kg (203 lb). Use suitable cribbing to place the heat exchanger in a flat position on the rear frame. This position can help ensure proper alignment during the procedure.
Remove bolts (2). Install Tooling (A) in spacers (3). Apply Tooling (C) to the threads of the nut and the threads of the guide stud prior to installation. Install the thrust bearing, the hard washer, and the nuts on the guide stud. Ensure that Tooling (A) is securely installed. Place two nuts together and tighten the outer nut to install Tooling (A). Position the thrust bearing, the hard washer, and one nut against the front frame.
Remove bolts (1) from the front frame. Repeat Step 4 to install Tooling (A).Note: It is not necessary to remove the bolts from the rear frame.

Illustration 4 g06408600
Typical Example
Install Tooling (B).
Loosen the nuts on Tooling (A) evenly. Ensure that Tooling (A) does not loosen from the spacers.Note: Do not loosen the nuts more than one turn per nut until the plate assemblies are no longer compressed.Note: As the front frame rises, the plate assemblies will slide along Tooling (B).

Typical Example
Remove Tooling (A) from the spacers.
Use two people to remove front frame (5). The weight of front frame (5) is approximately 29 kg (64 lb). Remove front frame (5). Remove the collars and the liners from front frame (5).Note: Ensure that the collars and the liners are not damaged during removal from the front frame.Note: The liners are removed from the front of the front frame.Note: Note the order and orientation of the plate assemblies and the gaskets during removal.
Remove plate assemblies (6).Note: Check the O-ring seals, the gaskets, and the seals for wear or for damage. Replace the components, if necessary.
