0000001801 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
Adjustment method [supply voltage Vi, dummy bolt (A)]
1. Hold the dummy bolt (A) against the control lever at position N = N1 and Q = Q1 and fix using the lock nut.
2. When adjusting the potentiometer, position the control lever to contact the dummy bolt (A).
Adjust the potentiometer so that the output voltage is V1.
3. After completing adjustment remove the dummy bolt (A). Confirm that the potentiometer output voltage is as specified at the control lever idle position and full position.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 26% 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
Before Failure:
1 - Update Engine Software, refer to Troubleshooting ? ECM Software ? Install, ensure to follow the steps to save the Engine Configuration data.
2 - Apply Carlson Service Number 14CP-013 - Regeneration Interlock Ground Wire Kit, contact a Carlson Paving Products Dealer for Kit Part Number 14CP-013.
After Failure:
1 - Refer to Steps 1 and 2 of the Before Failure actions.
2 - Service CCB Filter and replace with new filter, refer to Operation and Maintenance Manual ? Engine Crankcase Breather element ? Replace.
3 - Remove Diesel Particulate Filter, Refer to Disassembly and Assembly - Diesel Particulate Filter - Remove - wall Flow Diesel Particulate Filter.
4 - Move the Diesel Particulate Filter Assembly to a suitable work surface.
5 - Refer to Specifications - Diesel Particulate Filter (Wall Flow Diesel Particulate Filter(DPF)), remove V Band Clamps (1) and (4), carefully split assembly and remove DPF Canister element.
6 - Using new DPF Kit Filter, reassemble the Diesel Particulate Filter Assembly noting the alignment marks previously made in Step 3, refer to Specifications - Diesel Particulate Filter (Wall Flow Diesel Particulate Filter(DPF)).
7 - Reinstall the Diesel Particulate Filter assembly, Refer to Disassembly and Assembly - Diesel Particulate Filter - Install - wall Flow Diesel Particulate Filter.
8 - As the DPF has been replaced, ensure the ?DPF Replacement Reset? procedure is performed using CAT ET, refer to Troubleshooting - Service Tool Features - Components Replacement Resets.
