Oilwell A-560-PT Mud Pump Parts: Liner Packing and Multi-Part Rod References

For a Oilwell A-560-PT mud pump parts enquiry, the complete component reference is more useful than the pump model alone. The Mud King Products catalogue separates expendable parts by nominal size, component family and installed arrangement. This guide transcribes the identifiable supplier-number entries associated with Oilwell A-560-PT, with their original page and table context, so a buyer can assemble a clearer maintenance RFQ.

Liner Packing and Multi-Part Rod References

The A-560-PT liner sheet lists MK-0287-series liners with packing references that change by size. The 4-inch entry pairs MK-0287-40 with MKG-0753, while the 7-inch entry pairs MK-0287-70 with MKG-0756. The valve-cover gasket is separately listed as MKG-0732; the cylinder-head gasket column is marked N/A in this source.

The rod table distinguishes piston rod MK-0283-C, sub rod MK-0283-A and connecting rod MK-0283-D, followed by the extension rod, clamp and nut. Name the required piece instead of requesting an unspecified rod assembly. This catalogue sheet does not provide an A-560-specific module BOM, so the A-600 or larger A-series module tables are not presented as automatic substitutes.

Read the catalogue reference correctly

The accompanying reference list covers the identifiable number-bearing cells in the relevant source tables, not a complete original-manufacturer bill of materials. MK and MKG identify supplier catalogue references; their prefixes, punctuation and combined suffixes are retained. A value marked N/A or left blank is not replaced by an invented number. A shared model heading records the catalogue scope and does not by itself confirm interchangeability on an individual pump.

Information to send for parts matching

Send the pump nameplate and serial number, full reference including its prefix, required quantity and a photograph of the installed or removed component. For liners and pistons, add the nominal size and sealing arrangement. For fluid-end hardware, identify the module configuration and whether an individual component or a studded assembly is required. Keep any original equipment drawing number as a separate field rather than stripping the supplier prefix to assume an OEM match.

Review mud pump spare parts matching, compare liners, pistons, valves and seats, or send Pratt Oil a parts list for review. Matching and availability require confirmation; these references do not establish authorisation, inventory or a delivery promise.
