PROBLEM

Show/hide table

The existing 167-3466 Pressure Switch used in the Automatic Engine Speed Control (AEC) and the Smart-Boom systems can burst, leak, or lose electrical switching functionality on certain M313D, M315D, M316D, M318D, and M322D Wheeled Excavators. If the existing switch group fails, it can cause loss of Automatic Engine Speed Control or Smart-Boom function and/or loss of oil.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 1% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.

ACTION REQUIRED

Show/hide table

Replace the failed pressure switch (marked "A" in Images 1 and 2) with the improved 309-5769 Switch Group. Image 1 shows the location of the pressure switches on a standard machine's pilot manifold (306-8858 Valve Group-Solenoid (Standard)). The pressure switches are similarly located on the pilot valve of Material Handling (MH) machines equipped with a Hydraulic Cab Riser (306-8859 Valve Group-Solenoid (HCR)). Image 2 shows the pressure switch's location on the Smartboom Valve (251-7968 Valve and Lines Group-Boom - Smartboom).

If the 108-7516 Fitting-Adapter is removed or loosened during switch replacement, tighten it to a torque of 30+/-2 Nm and then tighten the new 309-5769 Switch Group to a torque of 12+/-2 Nm.
