Providing both references can simplify product identification and help customers cross-reference the required component between older and newer parts documentation.
3-Inch Washpipe Assembly
Upper Spacer Function
The upper spacer is one of several components that form the washpipe packing arrangement. Within the 3-inch washpipe system, upper, middle, and lower spacers are used together with packing and retaining components as part of the complete assembly.
Part Number 123285 is specifically identified as the upper spacer for the 3-inch washpipe. Correct identification is important because each spacer has a specific position within the washpipe assembly and should not be confused with the middle or lower spacer.
Related Washpipe Components
A typical compatible washpipe assembly includes several individual components, including a washpipe packing assembly box, upper spacer, middle spacers, lower spacer, holding ring, washpipe assembly, packing seals, snap ring, grease fitting, and securing hardware.
These components work together within the washpipe system, and replacement parts should always be selected according to their specific part numbers and positions within the assembly.
NOV TDS-11SA Top Drive Application
Compatible Top Drive Equipment
Legacy Part Number 123285 is listed in spare parts references for the NOV / Varco TDS-11SA top drive system. The TDS-11SA is a 500-ton NOV top drive used in land and offshore drilling applications.
Customers maintaining TDS-11SA equipment may encounter Part Number 123285 in spare parts catalogs, equipment drawings, maintenance documentation, or previous purchase records.
Washpipe System Maintenance
Washpipe components operate in demanding drilling conditions involving drilling fluids, rotation, pressure, vibration, and extended operating periods. Individual components may therefore require inspection or replacement during scheduled top drive maintenance.
When servicing the washpipe system, customers should identify each component according to the applicable equipment documentation and manufacturer part number before ordering replacement parts.
Part Number Cross Reference
123285 and 10448935-001
The primary references for this component are Legacy Part Number 123285 and Oracle Part Number 10448935-001. Including both numbers in purchasing records can assist maintenance departments and procurement teams working with different generations of NOV equipment documentation.
The description “Upper Spacer, 3 Inch Washpipe” provides an additional reference for distinguishing this component from the corresponding middle and lower washpipe spacers.
Importance of Correct Part Identification
Upper, Middle and Lower Spacers
The washpipe assembly contains several spacer components that may appear similar but occupy different positions within the assembly. Part Number 123285 is specifically the upper spacer.
Customers should not substitute a middle or lower spacer based only on visual similarity. The correct manufacturer part number and equipment parts list should be used to confirm the required item.
Verify Before Ordering
Before placing an order, verify the part number, washpipe size, equipment model, and application against the relevant equipment documentation. If available, providing the top drive serial number or spare parts list reference can also assist with product verification.
