Dielectric Grease
Dielectric grease was applied to the following connections at
the factory when the crane was assembled. When servicing
electrical connections, dielectric grease must be re-applied
to these connections.
• All Deutsch Connectors
• All Valve Solenoid connections on Hydraulic valves and
Transmissions
• All Harness Connections
• RCL Module Connections (except M12 and M8
connectors)
Excluded Connections
Do not apply dielectric grease to the following connections:
• All Connections Inside the Cab
• M12 and M8 Connectors
• Pin-type Contacts
Applying Dielectric Grease to an Electrical Connector
Use the following procedure to apply dielectric grease to an
electrical connection. Grease should be applied immediately
prior to securing the connector. Ensure that grease is applied
to all terminal sockets (Figure 1-1).
1. Check the connection for moisture before application of
the grease. If moisture is found, clean or replace the
connector as necessary.
2. Screw a tip or trigger assembly on to the can of dielectric
grease if necessary.
3. Apply the grease onto socket (female) contacts.
4. Use a clean towel to remove excess grease from the
surface of the connector, and wipe grease into the
terminal sockets (Figure 1-1).
5. Ensure grease is applied to each terminal socket. The
towel with excess grease can be used to fill empty
terminal sockets (Figure 1-1).
6. Ensure grease is applied to the entire surface of the
connector’s rubber seal (Figure 1-1).
NOTE: Do not allow grease to come in contact with any
painted surface, or any other components.
7. If clean up is necessary, contact cleaner or petroleum
distillates can be used.
8. Secure the connector when complete.
FATIGUE OF WELDED STRUCTURES
Highly stressed welded structures are subject to cracking
(fatigue) when repeatedly subjected to varying stresses
caused by twisting, shock, bending, and overloads. Inspect
equipment periodically for weld fatigue. The frequency of
