Product Overview

The oil pump is responsible for drawing engine oil from the sump and maintaining circulation through the lubrication system. Low oil pressure that persists after checking oil level, viscosity, filter condition, pickup restrictions, bearing clearance, and the pressure sender can point to a worn pump.

The 129900-32001 pump family appears across Yanmar industrial engines and Komatsu equipment using derivative 4D94 engines. Matching the engine code and pump reference is more dependable than ordering by machine brand alone.

Key Features & Performance

  • Lubrication oil pump for supported Yanmar TNE/TNV and Komatsu 4D94 engine families
  • Reference 129900-32001 with later/cross-number listings in the same pump family
  • Designed to restore oil circulation when the original pump is worn or damaged
  • Machine applications vary, so engine identification is the primary fitment check

Specifications & Reference Numbers

  • Primary reference: 129900-32001
  • Component: Engine lubrication oil pump
  • Approx. catalog dimensions for matched pump: 135 × 135 × 110 mm; confirm against removed part

Before You Order

Verify the complete engine model and the pump number on the parts breakdown. Low oil pressure has several possible causes, so diagnose pickup, bearings, relief valve, oil/filter and sender before assuming the pump is the only fault.

Frequently Asked Questions

Q: Will a new oil pump always fix low oil pressure?
A: No. Excessive bearing clearance, a restricted pickup, pressure-relief problems, incorrect oil, or a faulty sender can produce similar symptoms.

Q: Can this pump be identified by the machine model alone?
A: Engine code and part number are safer because Yanmar engines are used in many different machines.
