KIT-HYD CYLINDER SEAL 4308744 - Caterpillar

Installation Procedure
Perform the following procedure to help prevent excessive ESD around the 357-0663 Relief Valve As.Only perform the following procedure if the machine is consistently operating in ambient temperatures below 0° C (32° F).Report the implementation of the solution that is identified below in a Dealer Work Order and attach photographs of the installation in Service Information Management System (SIMSi).The solution consists of two separate parts:
Block the lower section of the cooling compartment door to reduce the exposure of the relief valve to the dusty air flow.
Use of conductive tape to ground the fuel relief valve and drain the static charges on the surface of the valve.

Remove Bolts (8).
Ensure that there is a good ground path between Bracket (7) and the mounting point of the bracket. If necessary, remove paint.Note: Do not use solvents to remove the paint.
Install Bracket (7) and Bolts (8). Tighten Bolts (8) to a torque of 55 N m (41 lb ft).
Remove Bolt (5).
Inspect the body of Valve (4) for damage to the paint finish. Refer to Illustration 4.
If the fuel system relief valve is leaking, install a new 383-3462 Fuel Line (6).If the fuel system relief valve is not leaking, remove the paint from Area (Z).Note: Do not use solvents to remove the paint.

Install Bolt (5) so that Tooling (B) grounds the fuel system relief valve to the mounting bracket. Tighten Bolt (5) to a torque of 12 N m (106 lb in).
Turn the battery disconnect switch to the ON position. Turn the fuel system supply valve to the OPEN position.
Report the installation of this solution within a Dealer Work Order and attach photographs of the installation in SIMSi. Report the following Information:
Date and time of the work
Dealer name, location, and code
Machine model, serial number, and Service Meter Units (SMU)
Confirm that the fuel system relief valve is not currently leaking fuel
