Description of Change: The inappropriate use of the clean side evacuation ports amplifies the risk of introducing debris, which contaminates the entire clean side of the lubrication circuit.

The modified oil tubes, adapter, and elbows allow removal of the evacuation ports. Removal of the ports eliminates the evacuation ports from being an entry point for contamination.

Adaptable To: The modification has been made to the following parts:

• 121-5732 Adapter

• 153-6601 Tube As

• 186-4184 Tube As

• 186-4192 Elbow

• 304-3341 Tube As

• 316-1167 Elbow
