PROBLEM

Show/hide table

The existing air conditioning tubes can fail in the brazed area on certain 973C Track Loaders. If the existing tube fails, refrigerant will leak and the air conditioning system will not work properly. Adding a bracket to support theses tubes will prevent the tubes from breaking.

This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.

ACTION REQUIRED

Show/hide table

Add a 322-1521 Bracket in order to support the air conditioning tubes.
Use the hardware listed in the Parts Needed to install the new bracket on the air conditioning compressor as shown in the image below.

NOTE: If the repair is done Before Failure, the air conditioning system needs to be evacuated before loosening the tubes.

Loosen the tubes from the compressor during bracket installation in order to avoid stress on the tubes. Tighten the tubes when the bracket is fully installed.
Care must be taken to route the harness and wires to avoid interferences with sharp edges.
