Rework Procedure
1. Locate and remove the 241-8368 Main Power Relay(s) on the machines listed above.
2. Mount the new Main Power Relay(s)
3. Clean and Install the appropriate Bus Bars / Ring Terminals.
4. Ensure the additional 4B-4277 Washers are placed between the nut and the Bus Bar/Ring Terminal. Use the hardware stack-up shown in Image 1.1.1 as a reference.
Image1.1.1
4. Tighten the Nuts to 9 +/- 0.5 Nm (80 +/- 4.4 lb in). This torque is critical for a good electrical connection. Over torquing of the nuts will cause damage to the Main Power Relay Cap and studs.
Note: A few degrees of stud rotation is acceptable. If the stud moves with the attached ring terminal, it is not considered to be a loose bolted joint.
Note: For machines that use bus bars, ensure that the vinyl coating on the bus bars is not part of the bolted joint. Cut off any portion that interferes with the electrical connection.
5. Secure the cables and wiring within 5 inches of the relay if possible.
Note: Do not secure the wiring directly to the relay housing. The relay housing gets hot and may deteriorate the insulation.
