In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 32% 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
Prior to Disassembly:
Remove/Turn off all power to the dosing cabinet.
Lock Out and Tag Out the master disconnect.
Follow all mandated safety rules.
Please refer to the attached Rework Procedure.

Rework Procedure
Early production dosing cabinets under went several changes with the Diesel Exhaust Fluid Back Pressure Valves that were installed at the factory. (A) Plastic Housing, (B) Stainless Steel Housing, and (C) Stainless Steel Body with Plastic Cap. Refer Image 1.1.1.
Identify the Diesel Exhaust Fluid Back Pressure Valve in the dosing cabinet, and proceed to the appropriate rework procedure below.
Remove the Diesel Exhaust Fluid Back Pressure Valve from dosing cabinet. Refer to Image 1.1.2.
Disassemble and replace the internal support disc. Refer to Image 1.1.3.
Reassemble valve and tighten the assembly screws 5 Nm ( 43 in lb ). Reinstall valve into dosing cabinet.
Once Diesel Exhaust Fluid Back Pressure Valve has been reinstalled, it is necessary
to set the back pressure valve at ~40 psi. This is an important adjustment. If the back pressure valve is set too low it will not be able to seal against the DEF head pressure, and can flood the reactor. If the valve is set two high, it can stop all flow of DEF, and will force DEF out the pump pressure release valve, possibly damaging the pump.
Procedure to Set Back Pressure Valve
Plastic Housing (A) or Stainless Steel Housing (B)
The field method of setting the valve is to back off the adjustment screw until the spring pressure is released, tighten the screw until contact is made with the spring, then tighten the screw two complete revolutions. The adjustment screw gives ~20 psi per revolution of the screw, so two turns sets it at about 40 psi.
Note: Special care should be taken when determining when the screw makes contact with the spring. Occasionally the screw can be tight, making it hard to determine when the screw makes contact with the spring. Lubricating the screw can help.
Stainless Steel Body with Plastic Cap (C)
The valve may be marked as BPM025SV50P. Refer to Image 1.1.4. If the spring has 9 coils (A), unscrew
