TL;DR
Match each NOV Type P service tool to its specific function, pump model and applicable OEM document before accepting an identification.
- NOV booklet 25-101131, page 21, lists different pinion-rotation adapter references for 7-P-50, 8-P-80 and the 9-P-100 through 14-P-220 group.
- The same page gives a different model grouping for liner-bushing puller plates. Sharing one tool number does not establish that an entire tool set is interchangeable.
- A published number is a document reference, not proof that an unmarked tool fits the installed equipment or is approved for use.
Use the model-specific examples below to prepare a focused identification request. They do not establish stock availability, supply scope or replacement-tool approval.
Scope: identify tools, not an operating procedure
This guide covers document identification for the Type P models listed on NOV page 21. Confirm the nameplate model, serial number, current applicable manual and any approved modifications. This is not a tool-use sequence, lifting-capacity statement or authorization to work on the pump.
Tool use and intrusive verification require knowledgeable, authorized personnel following the approved procedure, with shutdown, energy isolation and verified pressure release as applicable. Keep guards in place for any approved operating observations. Do not rotate machinery or try fitting a tool merely to complete this worksheet.
How do the two model groupings differ?
They must be read separately for each tool. The following pairs summarize the pinion-rotation adapter and liner-bushing puller-plate entries on NOV page 21:
- 7-P-50: adapter 1294140; puller plate 1294164.
- 8-P-80: adapter 1291225; puller plate 1291164.
- 9-P-100: adapter 1290140; puller plate 1290164.
- 10-P-130: adapter 1290140; puller plate 1290164.
- 12-P-160: adapter 1290140; puller plate 1292164.
- 14-P-220: adapter 1290140; puller plate 1295164.
These are the booklet's references for the named tools, not a complete service-tool list. In particular, the common adapter reference across four models does not make their puller-plate references identical. Use NOV 12-P-160 and NOV 14-P-220 as catalogue navigation, then obtain equipment-specific confirmation for an actual item.
Why separate tools that appear next to each other?
Each sketch has its own tool name and number. On page 21, the wrench associated with the pinion-rotation adapter is listed as 2402290; this is distinct from the model-specific adapter references above. The liner-clamp lifting tee-handle bolts are separately labelled 1290206 for the short version and 1290207 for the long version. NOV page 21.
Do not merge neighbouring captions into one assembly number or infer lifting capacity from the word “lifting.” Page 22 contains another group for valve-pot work. When a request concerns a valve seat or valve cover, return to that tool group and its model entries rather than carrying over a number from page 21.
Identification and storage checklist
These fields are editorial recommendations for a traceable tool record:
- Equipment: nameplate model, serial number and applicable manual/drawing revision.
- Tool: intended function, exact OEM caption and the model-specific reference being checked.
- Physical evidence: legible markings, permitted photographs and relevant document references; record an absent marking as unknown.
- Confirmation: person responsible, applicability evidence and any unresolved discrepancy.
- Storage: assigned cabinet or location, inventory label and return/check status.
NOV page 21 recommends convenient dedicated storage to reduce tool loss. Storage status does not establish condition or fitness for use. Leave uncertain identification open; seek authorized assessment rather than trial fitting or modifying a tool.
FAQ
Does adapter 1290140 mean every tool is shared across those models?
No. Page 21 groups that adapter across several models but lists different puller-plate references for some of them. Check each tool independently.
Is 2402290 the adapter number?
The cited page identifies 2402290 as the associated wrench. The adapter references are model-specific and are listed separately.
Can a photograph alone approve an unmarked tool?
No. A photograph supports identification, but applicability and authorization require the relevant documentation and qualified assessment.
Do the short and long tee-handle numbers prove a lifting rating?
No. The page distinguishes the versions by number and length label; this guide provides no load rating or lifting approval.

Next step
For a tool or parts identification enquiry, provide the pump identity, intended tool function, cited manual page and existing markings or permitted photographs. Request documented applicability for the actual item, including any unresolved modification or superseded reference.
