Typical example of the 456-6048 DPF TOOL GP
Use the following procedure to measure the amount of ash in the DPF:
Use a wire with the maximum diameter of 1.04140 mm (0.041 inch) or the 456-6048 DPF TOOL GP. Hold the wire or tool so that the end of the wire is just inside the cell approximately 6.35000 mm (0.25 inch).
Drop the wire into the cell of the DPF.
Mark the wire at the top of the cell where the wire exits from the DPF.
Measure the depth that the wire dropped by measuring from the mark to the bottom tip of the wire.
Record the measurement.

The DPF is ready to be returned to service. DPF Ash Service
Purpose
The engine ash model must be reset whenever the filter is cleaned or replaced. Reseting the ash model places the DPF ash volume back to the "Clean State". The resetting will allow the regeneration of the DPF to function properly. Cat ET Location
