A 3E-2034 Pressure Switch Assembly can be used in place of the 9W-0263 Pressure Switch Assembly on off-highway tractors, trucks and quarry trucks equipped with ARC. The 3E-2034 Pressure Switch Assembly will give longer service life than the 9W-0263 Pressure Switch Assembly.

The new 3E-2034 Pressure Switch Assembly has a two-pin Sure-Seal connector. A 7N-7780 Pin, a 7N-7779 Socket and a 7N-9737 Plug Housing will need to be installed on the machine wiring harness assembly to accomodate the 3E-2034 Pressure Switch Assembly. The connector parts are in the 6V-3000 Sure-Seal Connector Kit. Secure the mated Sure-Seal connector with a 3T-3048 Clip or a 9G-9150 Clip and a suitable 3/8inch bolt.
