Genuine VOLVO Engine Oil Pump Assembly — Gear‑Driven Forced Lubrication Core Solution
The Genuine VOLVO Premium Heavy‑Duty Engine Oil Pump Assembly (Part Numbers: 23170999 / VOE 23170999 / 21489736), also known as Primary Forced‑Lubrication Gear Pump, is the core lubrication component for VOLVO B‑series, D‑series & E‑series diesel engines. Gear‑driven by crankshaft, it supplies pressurized engine oil to bearings, camshaft, turbocharger and piston cooling nozzles. Replacing worn oil pumps restores stable oil pressure, reduces friction heat and prevents catastrophic engine seizure under heavy‑load operation.
Core Technical Advantages
Precision‑Forged Steel Internal Gears: Micro‑shaved high‑strength gears deliver steady oil pressure, high volumetric flow and low operational noise.
Integrated Pressure Relief Valve: Factory‑calibrated spring‑loaded valve releases excess cold‑start pressure to protect oil filters and seals from bursting.
Wear‑Resistant Die‑Cast Alloy Housing: Stress‑relieved alloy shell prevents internal bypass leakage and long‑term body wear.
Induction‑Hardened Precision‑Ground Drive Shaft: Resists bending/fracture under continuous high‑RPM crankshaft torque loads.

Critical B2B Procurement & Maintenance Guidelines
B2B Procurement Strategy
Soot buildup, poor oil maintenance and metallic debris cause gear/housing scoring and hot‑idle pressure drop, triggering low‑oil‑pressure alarms and engine seizure. Stock 23170999/21489736 for major engine overhaul orders. Cross‑sell with bearing sets, overhaul gaskets, oil coolers and high‑efficiency oil filters for complete engine rebuild kits.
Common Failure Symptoms
Low hot‑idle oil‑pressure warning caused by worn gears/housing and hot‑oil bypass leakage
Loud valve‑train ticking/chattering from insufficient oil supply to camshaft and rocker arms
Rising oil temperature & poor fuel economy due to excessive internal friction from reduced lubrication flow
Clean oil pan/pickup screen thoroughly to remove metal debris, disconnect main battery switch (17418494). Prime new pump with clean engine oil before installation, verify proper gear‑mesh backlash, install new gaskets, replace oil filters, monitor oil‑pressure build‑up via dashboard monitor (14609502) and check for leaks after startup.
