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 specified for the Perkins 4006-23TAG3A diesel engine. It removes wear metal, soot and sludge from the oil before it reaches the bearings, turbocharger and oil pump, and it should be replaced at the interval stated in the Perkins 4006-23TAG3A service schedule.
A primary engine oil filter is a full-flow filtration element installed on the pressure side of a diesel engine's lubrication circuit. It captures particles — typically in the 10–25 micron range for full-flow media — before oil reaches bearings and the turbocharger, while a bypass element handles finer soot removal. On the Perkins 4006-23TAG3A, the 4759205 element is the primary stage of that two-stage protection strategy.
What does the 4759205 filter actually protect on a Perkins 4006-23TAG3A?
The Perkins 4006-23TAG3A is a 23-litre, six-cylinder turbocharged and air-to-air charge-cooled diesel used in continuous power generation and heavy industrial duty. Its lubrication circuit feeds main and big-end bearings, the camshaft, the turbocharger centre housing and the piston cooling jets.
Contaminated oil is the single most common cause of premature bearing wear on this engine family. The 4759205 primary element is the first line of defence: it holds the bulk of the debris load so the bypass element can work on fine soot without plugging prematurely.
Because the 4006-23TAG3A often runs at 1,500 rpm (50 Hz) or 1,800 rpm (60 Hz) for generator drive, oil flow and filter loading are predictable — which is why sticking to the OEM-specified element matters more than saving a few dollars on a lookalike.
How do you verify the 4759205 fits your engine?
Match three things before you order: the OEM part number 4759205, the engine model 4006-23TAG3A, and the engine serial number. Perkins builds several 4000-series variants with different filter heads, and a filter that threads on correctly can still have the wrong bypass-valve setting or media rating.
If the original element is missing or unreadable, cross-reference from the Perkins parts book for your serial range rather than from a generic filter catalogue. Where a cross-reference is ambiguous, 3G Electric will confirm against the engine serial before quoting.
Specification reference
The table below summarises the attributes buyers most often ask about. Values shown are the OEM part identity and the filtration attributes typical of this filter class; confirm final media rating and bypass setting against the Perkins 4006-23TAG3A parts listing for your serial number.
| Attribute | Value / Specification |
|---|---|
| OEM part number | 4759205 |
| Filter position | Primary (full-flow) |
| Engine application | Perkins 4006-23TAG3A, 23 L turbocharged diesel |
| Typical full-flow rating | 10–25 micron nominal |
| Operating oil pressure range | 4–7 bar (58–102 psi) typical for this engine class |
| Operating oil temperature | Up to 120 °C (248 °F) continuous |

| Service interval | Per Perkins 4006-23TAG3A maintenance schedule |
Which filter type suits your duty cycle?
Primary full-flow elements are the standard choice for the 4006-23TAG3A in standby and prime-power service. Where the engine runs continuously on heavy fuel or in dusty environments, buyers often pair the primary element with a finer bypass element and shorten the oil-sampling interval.
For compressed-air and pneumatic circuits on the same site — instrument air, control panels, painting — the same filtration logic applies at a different scale. Coalescing and activated-carbon filters protect downstream equipment from oil aerosol and vapour in exactly the way the 4759205 protects the engine's bearings.
- Standby generator: primary element at the OEM interval, annual oil analysis.
- Prime/continuous power: primary element plus bypass element, quarterly oil sampling.
- Dusty or high-soot duty: shorten the primary interval and monitor differential pressure where a gauge is fitted.
How to choose the right oil filter supply
- Confirm the OEM number and engine serial. 4759205 must match the 4006-23TAG3A serial range, not just the model name.
- Check the media and bypass rating. A correct thread and gasket do not guarantee the correct bypass-valve cracking pressure.
- Verify the source. Ask for traceability on the OEM number; counterfeit elements are a known problem in export channels.
- Match the interval to duty. Standby, prime and continuous ratings carry different service intervals.
- Plan the logistics. For Worldwide buyers, confirm export documentation, packing and Incoterms before the order ships.

Frequently asked questions
What is the 4759205 engine oil filter used for?
The 4759205 is the primary full-flow lubricating-oil filter for the Perkins 4006-23TAG3A diesel engine. It removes wear debris, soot and sludge from engine oil before it reaches bearings, the camshaft and the turbocharger, protecting the lubrication circuit between scheduled oil changes.
How often should the 4759205 be replaced?
Replace it at the interval in the Perkins 4006-23TAG3A maintenance schedule for your duty rating. Standby generators typically follow annual or 500-hour intervals, while prime and continuous power applications often require shorter intervals supported by regular oil sampling.
Can I use a cross-reference filter instead of the OEM 4759205?
Only if the cross-reference is confirmed against your engine serial number. Thread and gasket dimensions can match while the bypass-valve setting and media rating differ, which risks unfiltered oil bypassing the element under cold-start pressure.
Do you ship the 4759205 to Worldwide destinations?
Yes. 3G Electric supplies Worldwide with export documentation experience and Incoterms-neutral terms. Lead time depends on stock position and destination; confirm the engine serial and required quantity when requesting a quote so we can confirm availability and shipping.
What else on site uses similar filtration?
Compressed-air systems on the same site use coalescing and activated-carbon filters to remove oil aerosol and vapour. 3G Electric stocks these alongside engine filtration, so instrument air, control panels and painting operations can be protected in the same order.
