>>>>>>I found out today from REXROTH themselves that they have discontinued this pump and no rebuild parts , or complete pumps (new or remaned) will be offered. NO PARTS PEOPLE...….AT ALL. Once Cat's inventory on these is exhausted, your screwed!!!! They are offering NO REPLACEMENT either.This machine has 4288 hours. This is original equipment and has never been into before today. BUYER BEWARE ON THESE......and they are used in several models of skid steers.
Is it the 4425637 pump? There is a modification procedure to install an updated pump, part number 4876181.
