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 lube-oil filter for the Perkins 4006-23TAG3A diesel engine, protecting the bearings, turbocharger and oil pump by removing wear particles and soot from the pressurised oil circuit. Buyers should confirm thread size, seal dimensions and bypass-valve rating against the engine's parts list before ordering.
A primary engine oil filter is the full-flow element installed on the pressure side of a diesel engine's lubrication circuit; it filters 100% of the oil pumped to the bearings on every pass, typically capturing particles in the 10–25 micron range while a bypass valve opens if the element blocks. On the Perkins 4006-23TAG3A — a 23-litre, turbocharged and air-to-air charge-cooled six-cylinder industrial diesel — the 4759205 element is the specified primary filter, and it works alongside the engine's secondary/bypass filtration to keep oil clean between service intervals.
What does the 4759205 oil filter do on a Perkins 4006-23TAG3A?
The 4759205 element sits in the engine's full-flow filter housing and cleans all pressurised oil before it reaches the main bearings, big-end bearings, camshaft and turbocharger feed. On a 4006-23TAG3A, oil also cools and actuates components, so contamination control directly affects bearing life and turbo reliability.
Perkins specifies primary and secondary filtration on the 4000 Series because these engines run continuously in power generation, marine and heavy industrial duty. A blocked or incorrect primary element raises oil pressure drop, opens the bypass valve and lets unfiltered oil circulate — the classic route to accelerated wear.
How does a full-flow engine oil filter work?
Oil is drawn from the sump by the pump, pushed through the 4759205 filter element, and delivered to the engine galleries. The filter media traps particles; a spring-loaded bypass valve opens only if differential pressure exceeds its set point or the oil is cold and viscous at start-up.
An anti-drainback valve (where fitted) keeps oil in the galleries between stops, reducing dry-start wear. The element's burst pressure and pleat integrity matter on turbocharged engines, where flow and pressure pulses are higher than on naturally aspirated units.
4759205 filter specification reference
The table below summarises the attributes buyers should verify before ordering. Values shown are the reference characteristics for this filter family; always confirm against the engine's current parts list, as Perkins updates specifications over a build's life.
| Attribute | Reference value | Why it matters |
|---|---|---|
| Filter type | Full-flow (primary) spin-on / cartridge element | Filters 100% of pumped oil each pass |
| Nominal filtration | 10–25 micron range | Protects bearings and turbo feed |
| Bypass valve setting | Typically 1.0–2.5 bar differential | Prevents oil starvation if element blocks |
| Operating oil pressure | Typically 3–6 bar at rated speed | Confirms element burst margin |
| Operating oil temperature | Typically 80–110 °C continuous | Drives media and seal selection |
| Engine displacement | 23 L (4006-23TAG3A) | Sets oil flow and filter sizing |
| Service interval | Per Perkins maintenance schedule (hours-based) | Determines stocking quantity |
Which variants and applications use this filter?
The 4006-23TAG3A is a 23-litre turbocharged, air-to-air charge-cooled diesel used in standby and prime power generation, marine auxiliary duty, and heavy industrial drives. The same 4000 Series family spans several ratings, so always match the filter to the exact engine build plate, not just the series name.
- Power generation: standby and prime gensets running 50 Hz or 60 Hz, where oil changes follow running-hour schedules.
- Marine auxiliary: continuous duty with high ambient humidity — moisture ingress makes correct sealing critical.
- Industrial drives: pumps, compressors and crushing plant with dusty environments and long shifts.
- Export/retrofit builds: engines re-rated or re-located across markets, where the parts list must be re-verified.
How to select the right primary oil filter
- Confirm the engine build. Match the 4006-23TAG3A serial and build plate to the parts list — series-level matching is not enough.
- Verify thread and seal. Thread pitch, gasket diameter and seal type must match the housing to prevent leaks and bypass.
- Check the bypass rating. An element with the wrong bypass setting can starve or over-pressurise the circuit.
- Match media to duty. Continuous-duty and high-soot applications benefit from higher-efficiency media; short-cycle standby sets tolerate standard media.
- Plan the service interval. Stock enough elements for the oil-change schedule across your fleet, not just one unit.
- Buy from a supplier who can cross-reference. A distributor who interprets your demand will confirm the correct element rather than shipping the nearest match.

| WILKERSON M30-08-FM0 Coalescing Filter | Coalescing, 0.01 micron | 1 in NPT | 203 cfm | 200 psi | Heavy — painting and process air |
| PARKER 2 1/2 in NPT Coalescing Filter | Coalescing, 0.01 micron | 2 1/2 in NPT | 699 cfm | 232 psi | Heavy — high-purity instrumentation air |
| PARKER 1 1/2 in NPT Activated Carbon Filter | Activated carbon, odour and oil vapour | 1 1/2 in NPT | 339 cfm | 290 psi | Heavy — odour and vapour removal |
| SPEEDAIRE 1 in NPT Activated Carbon Filter | Activated carbon, odour and oil vapour | 1 in NPT | 117 cfm | 235 psi | Medium — painting and food processing |
Step up the ladder when flow demand rises or when downstream equipment is sensitive to oil aerosol: a 61 cfm coalescing unit suits a small tool circuit, while a 699 cfm Parker element is the right choice for a plant-wide instrument-air header. For odour and vapour removal rather than aerosol capture, move to an activated carbon stage after coalescing.

Frequently asked questions
What is the 4759205 engine oil filter used for?
The 4759205 is the primary full-flow lube-oil filter for the Perkins 4006-23TAG3A diesel engine. It removes wear debris and soot from pressurised oil before it reaches the bearings, camshaft and turbocharger, protecting the engine between scheduled oil and filter changes.
How do I cross-reference the 4759205 filter?
Cross-reference using the Perkins parts list for your exact engine build, then verify thread size, seal dimensions and bypass rating against the candidate element. Series-level matches are unreliable — confirm the build plate and serial before ordering, and ask your supplier to check the reference for you.
How often should the primary oil filter be changed?
Follow the Perkins maintenance schedule for the 4006-23TAG3A, which is based on running hours and duty cycle. Standby gensets and continuous marine duty have different intervals, so base your stocking plan on the schedule for each application rather than a single fleet-wide figure.
Can I use a non-genuine equivalent?
Yes, provided the equivalent meets the same thread, seal, bypass and filtration specifications. The risk is not brand — it is an element that fits physically but bypasses too early or filters too coarsely. Verify the specification, not just the appearance.
What is the lead time and delivery for Worldwide orders?
Lead time depends on stock position and destination. 3G Electric supplies Worldwide on incoterms-neutral terms with export documentation support; contact us with your engine build, quantity and destination port or site, and we will confirm availability and shipping options.
Do you supply filters for both 50 Hz and 60 Hz genset builds?
Yes. The 4006-23TAG3A is used in both 50 Hz and 60 Hz power generation, and the lubrication circuit is the same — but always confirm the engine build plate, since ratings and ancillaries can differ between market variants.
