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, a 23-litre six-cylinder turbocharged and air-to-air charge-cooled diesel used in generator sets and industrial power units. It filters the entire oil pump output before the oil reaches the main bearings, turbocharger and piston-cooling jets.
What is the 4759205 engine oil filter primary?
A primary engine oil filter is the full-flow element that every drop of oil passes through on each pass around the lubrication circuit. It is distinct from a secondary or bypass filter, which treats only a small slipstream of oil at a much finer rating.
On the Perkins 4006-23TAG3A the primary element is a spin-on canister with an integral bypass valve. When the element loads with soot or the oil is cold, the bypass valve opens so the engine is never starved of oil — unfiltered oil is better than no oil. That valve setting is one of the specifications buyers most often overlook when substituting a cheaper filter.
Perkins is the OEM brand behind the 4006-23TAG3A platform, and the 4759205 part number is the reference point for cross-referencing aftermarket equivalents. In compressed-air and fluid-handling plants, the same discipline applies to air-side filtration — brands such as SPEEDAIRE, Parker, WILKERSON and HANKISON publish micron ratings and pressure limits so buyers can compare like with like rather than guessing.
How does a primary oil filter work on the 4006-23TAG3A?
Oil is drawn from the sump by the engine-driven pump, pushed through the primary filter, then routed to the main gallery. From there it feeds the crankshaft, camshaft, turbocharger bearing housing and piston-cooling jets before draining back to the sump.
The filter media is a resin-bonded or synthetic-pleated paper that traps particles in the 10–25 micron range while allowing high flow at low pressure drop. A strong centre tube resists collapse during cold starts, when oil viscosity and differential pressure both spike.
Because the 4006-23TAG3A is a turbocharged engine, the filter also protects the turbo bearing clearances, which are measured in microns. Contaminated oil is the single most common cause of premature turbo failure on this platform.
Specifications to verify before you buy
The table below lists the attributes that determine whether a filter will fit and perform correctly. Always confirm against the engine's build list, because Perkins applied more than one filter configuration across the 4006 range.
| Attribute | Typical value / requirement | Why it matters |
|---|---|---|
| Part number | 4759205 (primary) | OEM reference for cross-referencing |
| Filter type | Full-flow spin-on canister | Filters 100% of pump output |
| Filtration rating | Nominal 10–25 micron | Balances debris capture vs. flow |
| Bypass valve setting | Typically 1.0–2.5 bar (14–36 psi) | Prevents oil starvation when cold or loaded |
| Thread size | Confirm against engine build list | Wrong thread = no fit, no seal |
| Operating temperature | Up to 120 °C (248 °F) sump oil | Media and gasket must survive hot oil |
| Service interval | Per Perkins maintenance schedule | Typically 250–500 hours on gensets |
Where a value is not published on the filter you are considering, treat that as a red flag. A supplier who cannot state the bypass setting or micron rating cannot guarantee engine protection.
Primary vs. secondary filtration: which do you need?
Most 4006-23TAG3A installations run a primary full-flow filter and, on some builds, a secondary bypass filter. They are not interchangeable.
- Primary (4759205): full-flow, protects the whole engine, replaced every service interval.
- Secondary / bypass: slipstream only, finer rating, extends oil life by removing soot and sub-micron contaminants.
- Fuel and air filters: separate circuits — do not confuse them with the lube-oil filter when ordering.
If your engine is on extended oil-drain intervals, the secondary filter becomes more important, not less. Skipping it shifts the whole contaminant load onto the primary element.
How to select the right 4759205 filter
- Confirm the engine build. Check the serial number and build list — Perkins fitted more than one filter head across the 4006 family.
- Match the bypass valve setting. A filter with the wrong bypass pressure can either starve the engine or let debris circulate.
- Verify the micron rating. Nominal 10–25 micron is typical; anything coarser shortens bearing life.
- Check the gasket and thread. Measure the thread pitch and confirm the gasket seat diameter before ordering in volume.
- Consider duty cycle. Standby gensets and continuous prime-power units have different service intervals.
- Buy from a supplier who can cross-reference. A distributor who stocks adjacent filtration lines can confirm fitment rather than guess.

Step up the ladder when flow demand rises: a 61 cfm unit suits a single pneumatic tool, while a 699 cfm Parker unit suits a plant-wide air header. Match the connection size to your existing pipework before ordering — adapters add cost and leak points.
Worldwide sourcing, export documentation and lead times
3G Electric supplies the Worldwide market with incoterms-neutral quotations in USD. We handle export documentation, packing lists and commercial invoices as standard, and we can quote FCA, FOB or CIF depending on your freight preference.
Where a plant runs both 50 Hz and 60 Hz generator sets, the same 4759205 filter applies — the lube-oil circuit is frequency-independent. What changes is the service interval: 60 Hz gensets running at 1800 rpm and 50 Hz units at 1500 rpm accumulate hours at different rates, so plan spares accordingly.
For buyers in regions with limited local stock, we recommend holding at least one full service set — primary filter, secondary filter, fuel filters and air filter — so a single delayed shipment never stops a generator.
