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 oil filter element for the Perkins 4006-23TAG3A diesel engine. It filters the entire oil flow before it reaches the bearings, turbocharger and oil galleries, and it should be replaced at the interval stated in the Perkins 4000 Series workshop manual.
What is the 4759205 ENGINE OIL FILTER PRIMARY?
A primary engine oil filter is a full-flow filtration element installed in the main lubrication circuit of an internal combustion engine. It captures metallic wear particles, soot and sludge from the oil stream before that oil reaches critical bearing surfaces, the camshaft and the turbocharger.
The 4759205 is the primary element specified for the Perkins 4006-23TAG3A, a six-cylinder turbocharged and air-to-air charge-cooled diesel engine used in power generation and industrial drive applications. Because the 4006-23TAG3A is a high-output engine, oil cleanliness directly affects bearing life and turbocharger reliability.
Buyers sourcing this filter worldwide should treat it as a critical maintenance part, not a commodity. A filter that looks similar but has a different bypass valve setting, media rating or thread specification can reduce oil pressure or allow unfiltered oil to circulate.
How does a primary engine oil filter work?
Oil is drawn from the sump by the oil pump and pushed through the primary filter element before entering the main oil gallery. The filter media traps particles above its rated micron size while allowing clean oil to pass through at the required flow rate.
Most primary oil filters include an internal bypass valve. If the element becomes blocked or the oil is too cold to flow freely, the bypass valve opens to protect the engine from oil starvation — at the cost of temporarily unfiltered oil. This is why correct filter specification and timely replacement matter.
Perkins specifies the 4759205 as the primary element for the 4006-23TAG3A. Using a non-specified element can change bypass behaviour, collapse pressure or filtration efficiency, all of which affect engine protection.
Specifications and fitment
The table below summarises the key attributes buyers should confirm before ordering. Values are drawn from the Perkins 4000 Series documentation and the 4759205 part specification.
| Attribute | Specification |
|---|---|
| Part number | 4759205 |
| Filter type | Primary full-flow engine oil filter |
| Engine application | Perkins 4006-23TAG3A diesel engine |
| Engine configuration | 6-cylinder, turbocharged, air-to-air charge-cooled |
| Filtration role | Full-flow protection of bearings, camshaft and turbocharger |
| Typical replacement interval | Per Perkins 4000 Series service schedule (hours-based) |
| Market availability | Worldwide, via distributor and aftermarket channels |
Always confirm the engine serial number and build list before ordering. Perkins 4000 Series engines were produced in several variants, and the correct primary filter depends on the specific build.
Which filter type suits the Perkins 4006-23TAG3A?
The 4006-23TAG3A uses a primary full-flow oil filter as its main lubrication protection. Some installations also use a secondary or bypass filter for additional fine filtration, but the 4759205 is the primary element.
Buyers should not substitute a bypass filter for the primary element, and should not assume that a filter listed for a different Perkins 4000 Series variant will fit. Cross-reference by Perkins part number, not by physical appearance alone.
Where a secondary filter is also fitted, both elements should be replaced together at the scheduled interval to maintain balanced filtration.
Selection criteria for worldwide buyers
- Confirm the engine model and serial number. The 4759205 is specified for the 4006-23TAG3A; other 4000 Series variants may use different elements.
- Verify the part number. Order against Perkins part number 4759205, not a generic description.
- Check the filter type. Confirm the element is a primary full-flow filter, not a bypass or secondary element.
- Match the replacement interval. Follow the Perkins 4000 Series service schedule for hours-based oil and filter changes.
- Consider operating environment. Dusty, high-load or high-ambient sites may justify earlier replacement or oil analysis.
- Plan for export and lead time. Worldwide buyers should confirm documentation, packaging and shipping terms before committing to a maintenance window.

Step up the ladder when flow demand, connection size or pressure rating increases. For high-purity instrumentation air, choose a coalescing element with a 0.01 micron rating; for general pneumatic tool protection, a 1 micron element is often sufficient. For odour and oil-vapour removal, an activated carbon stage is added downstream.

Frequently asked questions
What is the 4759205 ENGINE OIL FILTER PRIMARY used for?
The 4759205 is the primary full-flow engine oil filter for the Perkins 4006-23TAG3A diesel engine. It removes wear debris, soot and sludge from the lubrication circuit before the oil reaches bearings, the camshaft and the turbocharger, protecting the engine from accelerated wear.
How do I confirm the 4759205 fits my Perkins 4006-23TAG3A?
Check the engine model plate and serial number, then cross-reference against the Perkins 4000 Series parts list. The 4759205 is specified for the 4006-23TAG3A; other 4000 Series variants may use different primary elements. When in doubt, send us the engine details and we will verify.
How often should the primary oil filter be replaced?
Replacement follows the Perkins 4000 Series service schedule, which is based on engine operating hours. Sites operating in dusty or high-load conditions may shorten the interval. Oil analysis is a practical way to confirm whether the interval suits your duty cycle.
Can I use a different brand of oil filter instead of the 4759205?
Only if the alternative is cross-referenced to Perkins 4759205 and matches the bypass valve setting, media rating and thread specification. A filter that looks similar but differs internally can reduce oil pressure or allow unfiltered oil to circulate, risking bearing and turbocharger damage.
Do you ship the 4759205 to buyers outside the United States?
Yes. 3G Electric supplies worldwide with export documentation experience and USD-denominated quotations. Lead time depends on stock position and destination; contact us with your required delivery window and we will confirm availability and shipping terms.
What is the difference between a primary and a secondary oil filter?
A primary filter is full-flow: all oil passes through it before reaching the engine bearings. A secondary or bypass filter treats only a portion of the oil flow at finer filtration, supplementing rather than replacing the primary element. The 4759205 is the primary element for the 4006-23TAG3A.
Key takeaways
- The 4759205 is the primary full-flow oil filter specified for the Perkins 4006-23TAG3A diesel engine.
