Reman Pump Numbers:
For pumps with package labels that indicate a remanufactured part number (0R, 10R, 20R), open the package to inspect the pump and actual part number on the identification sticker. If the pump has a remanufactured part number, the pump is not affected by this problem. Repackage the pump, and indicate on the box that it has been inspected per PI70468. Return the pump to stock.

If the pump has one of the new part numbers listed above, proceed to determine if this pump is in the suspect date code range.

Manufacturing process changes have been made on the piston pumps. All factories and service parts are in process of receiving new pumps. At this point no actions are required for field machines. Investigations are in process in order to determine if any actions are necessary.

We have initially identified pumps built after March 14, 2012 and before December 14, 2012 as "suspect". The date of manufacture is on the identification number plate of the pump, listed in the following format YYMMDDRHXXXX. Refer to Image1 for an example of the identification number plate on the pump. All rotating groups, swashplates, and pistons purchased during this time frame should also be removed from parts stock.
