TICO Document #: SFN-20240108B (formerly TES 170)

Description of Procedure: The solenoid fails and will not activate when the coil is energized. Replace the “STANCOR” solenoid with an “AMETEK” solenoid. Both of these solenoids are rated for 100 AMP continuous load.

Units Affected: Units 2017 and older with a Chassis with Cummins Engines QSB-IVi, QSB-IV, ISB-2007 thru 2016, PSI 8.8l engines. These Chassis PDC’s contain a K3 solenoid.

Parts Required: Solenoid 60015-1 (QTY 1)

Diode Assembly 910576 (QTY 1)

Planned Labor: 1.5 hours

Instructions:

  1. Park the vehicle on a flat surface, and apply the parking brake and chock wheels. If your company utilizes a “Lock Out, Tag Out” policy, you should employ it during this procedure.

  2. The chassis PDC is located over the transmission. The platform must be removed to facilitate this service.

  1. When replacing any of the solenoids on a chassis “PDC”, the following applies: First, ensure the electrical power to the solenoid is turned off. If need be, disconnect the battery cables supplying power to the “PDC”.

  2. Mark and remove the wires from the terminals on the old solenoid.

  3. Remove the solenoid and save the hardware for reuse.

  1. Mount the new solenoid in the same position as the unit being replaced. A slight origination may be required to mount on PDC using existing holes in the mounting plate. The K3 solenoid is identified and may be located in different positions depending on the individual PDC’s dependence on engine configuration. Only one configuration is used in this example, showing the replacement. See the figures below.

  1. Install the wires on the new solenoid in the same position as were removed. Install new diode assembly on #10 post. Red end must be on the positive wire, this is the yellow wire from the cab harness.

    Caution: DO NOT OVER TIGHTEN THE NUTS ON THE TERMINALS. Torque the #10-32 terminal nut to 40 in.lbs. Max Torque the 5/16-18 terminal nut to 95 in.lbs. max

  1. Connect battery cables and check that the circuit is obtained when the solenoid is activated. Install platforms. (For solenoid configuration, see figures on page 3.)

  1. Remove “Lock Out, Tag Out” plaque.

  1. Return vehicle to service.
