Some Earlier Vickers Hydraulic Pump Groups Are Not Available For Parts Service--Some Modification Is Needed To Install Replacement Pump Groups{5055}
Usage:
Some of the earlier hydraulic pump groups made by Vickers are no longer available for parts service. The earlier hydraulic pump groups were canceled because of very limited use. The part numbers shown in the Parts Chart are those of replacement pump groups that will fit in the same pump drive, give the same flow, but need a different size connection at the inlet port and/or the discharge port. The part numbers of the new and former pump groups are shown in the chart.
