4759205 Engine Oil Filter Primary for Perkins 4006-23TAG3A: Worldwide Buyer's Guide
Table of Contentsexpand_more
The 4759205 ENGINE OIL FILTER PRIMARY (4759205) is the primary full-flow lubricating-oil filter element specified for the Perkins 4006-23TAG3A diesel engine. It removes wear metal, soot and sludge from pressurised lube oil before that oil reaches the main bearings, camshaft and turbocharger, and it must be matched to the engine by OEM part number rather than by physical size alone.
What is the 4759205 engine oil filter primary?
A 4759205 engine oil filter primary is a full-flow (primary) lube-oil element that filters 100% of the oil pumped through a Perkins 4006-23TAG3A engine on every pass, typically capturing particles in the 10–25 micron range while passing the full oil-pump flow rate. It is distinct from a bypass or secondary filter, which treats only a fraction of the flow at finer ratings.
Perkins is the OEM brand behind the 4006-23TAG3A — a 23-litre, six-cylinder turbocharged and air-to-air charge-cooled diesel used in power generation, marine auxiliary and heavy industrial duty. Because that engine runs long, hot duty cycles, the primary filter is a scheduled wear item, not an optional accessory.
How does a primary engine oil filter work?
Oil is drawn from the sump by the lube pump and pushed through the filter housing, where the element media traps contaminants before the oil is distributed to the bearings and turbo feed line. A bypass (relief) valve inside the filter opens if the element blocks or the oil is cold and viscous, guaranteeing the engine is never starved of oil — dirty oil is better than no oil.
An anti-drainback valve, where fitted, keeps the housing primed so oil pressure builds immediately at start-up. On the 4006-23TAG3A this matters because turbocharger bearings rely on near-instant oil supply after a cold start.
4759205 filter specification checklist
Use the table below as a verification checklist. Confirm every value against the Perkins parts listing for your exact engine serial number before ordering — Perkins builds variants of the 4006 family with different filtration arrangements.
| Attribute | What to verify | Why it matters |
|---|---|---|
| OEM part number | 4759205 (primary element) | Positive identification; supersedes and cross-references key off this number |
| Engine model | Perkins 4006-23TAG3A | Confirms the 23-litre 4006 platform and TAG3A build |
| Filter function | Primary / full-flow | Distinguishes it from bypass or secondary elements |
| Filtration rating | Nominal micron rating per Perkins spec | Under-fine media can restrict flow; over-coarse media accelerates wear |
| Bypass valve setting | Per Perkins specification | Wrong setting risks oil starvation or unfiltered circulation |
| Thread / seat geometry | Per Perkins specification | Prevents cross-threading and leaks at full oil pressure |
| Operating pressure | Engine lube-system pressure range | Element must withstand cold-start pressure spikes |
| Operating temperature | Continuous sump temperature range | Media and seals must survive sustained hot-oil service |
Where a value is not published in the Perkins documentation you hold, request it from your supplier rather than substituting a "close enough" element. On a 23-litre turbocharged engine, a wrong bypass setting is a bearing-failure risk, not a minor deviation.
Which filter type suits your Perkins 4006-23TAG3A installation?
Most 4006-23TAG3A installations use a spin-on or cartridge primary element in a remote or engine-mounted housing. The correct choice depends on the housing fitted to your build, not on preference.
- Spin-on primary: fastest service, integral bypass and anti-drainback valves, common on generator-drive packages.
- Cartridge primary: lower waste volume per change, housing retained, common where fleet standardisation matters.
- Bypass/secondary element: fitted in addition to the primary on some duty ratings; finer media, partial flow — never a substitute for the 4759205 primary.
If your site also runs compressed-air or pneumatic control equipment alongside the engine package, the same contamination logic applies: WILKERSON M30-08-FM0 Coalescing Filter for Oil Removal and Parker High-Flow Coalescing Filter for Oil Aerosol Removal protect downstream instrumentation the way the 4759205 protects the engine.
How to select the right 4759205 filter — 7 steps
- Read the engine serial plate. Confirm 4006-23TAG3A and record the serial number; Perkins filtration arrangements vary by build.
- Match the OEM number. Order against 4759205 and accept only documented supersessions.
- Confirm primary vs bypass. Verify the element position in the lube circuit before purchase.
- Check the bypass valve setting. It must match the Perkins specification for your engine.
- Verify thread and seat geometry. Measure or cross-check against the removed element.
- Set the change interval. Follow Perkins service intervals for your duty cycle; shorten under high soot, high ambient or extended-idle operation.
- Plan the logistics. For Worldwide export, confirm lead time, packing and documentation before the service window, not during it.

Step up the ladder when flow demand rises or when downstream equipment is more sensitive: a 61 cfm coalescing unit suits a single pneumatic tool circuit, while a 699 cfm Parker coalescing filter suits a plant-wide air header feeding instrumentation and painting. For odour and oil-vapour removal rather than aerosol removal, move to an activated carbon stage after coalescing.

According to Perkins Engines Company Limited, Perkins 4000 Series Workshop Manual (4006 Electropak): "The engine oil filter must be renewed at the intervals given in the Maintenance Schedule. Use only the filter elements specified by Perkins."
Frequently asked questions
What is the 4759205 engine oil filter primary used for?
It is the full-flow lubricating-oil element for the Perkins 4006-23TAG3A diesel engine. It filters all oil pumped to the bearings, camshaft and turbocharger, removing wear metal, soot and sludge. It is a scheduled service item and should be renewed at the Perkins-recommended interval for your duty cycle.
How do I cross-reference the 4759205 filter?
Cross-reference using the OEM number 4759205 plus your engine serial number, then verify filtration rating, bypass-valve setting and thread/seat geometry against the Perkins parts listing. Do not cross-reference on dimensions alone — two elements can share a thread and can size while differing in bypass setting.
Primary vs bypass oil filter — what is the difference?
A primary (full-flow) filter treats 100% of the oil pump output on every pass and is the element the engine depends on for lubrication protection. A bypass filter treats only a fraction of the flow at a finer rating and supplements, but never replaces, the primary element.
How often should the 4759205 filter be changed?
Follow the Perkins Maintenance Schedule interval for the 4006-23TAG3A, then shorten it for high-soot, high-ambient or extended-idle duty. Oil analysis is the reliable way to tune the interval to your actual operating conditions rather than a fixed calendar.
Can 3G Electric supply the 4759205 filter to Worldwide destinations?
Yes. 3G Electric supplies Worldwide on incoterms-neutral terms with export documentation experience and USD pricing. Lead time depends on stock position and destination; confirm your engine serial and required delivery window when requesting a quote so we can commit to a realistic date.
Do I need a coalescing or carbon filter alongside engine filtration?
Only if your site also runs compressed air or pneumatic controls. Engine lube oil and compressed-air filtration are separate circuits. For air systems, a coalescing stage such as SPEEDAIRE 1 in NPT Coalescing Filter removes oil aerosol, and an activated carbon stage such as SPEEDAIRE Activated Carbon Filter removes odour and oil vapour.
Key takeaways
- The 4759205 is the primary full-flow lube-oil element for the Perkins 4006-23TAG3A — order by OEM number plus engine serial, never by size alone.
- Verify filtration rating, bypass-valve setting and thread/seat geometry before every purchase.
- Primary and bypass filters are not interchangeable; the primary protects the bearings and turbocharger on every pass.
- 3G Electric holds 169 products across related filtration categories and supports Worldwide export with USD pricing and documentation.
- Pair engine filtration with coalescing and activated carbon stages where compressed-air quality also matters.
