Perkins 4008-30TAG3 Diesel Engine for 1125–1250kVA Generator Sets

The 4008-30TAG3 is an 8-cylinder, turbocharged and air-to-air chargecooled diesel engine from the Perkins 4000 Series, supplied in engine-only configuration (Electro unit or ElectropaK) for the standby power generation sector. It is engineered for genset builders and operators requiring high power density at 1500rpm, with individual 4-valve cylinder heads and unit fuel injectors supporting fine fuel atomisation and controlled combustion for reliable baseload, prime, and standby duty. As part of the broader 4000 Series family, the 4008-30TAG3 shares core component architecture with other 4000 Series engines, supporting parts commonality and reduced stocking requirements across the range

Build List & Series Compatibility

4008-30TAG3 Build List

Both Build Lists refer to the same engine specification. The difference is production batch only — parts compatibility is identical across both designations.

4008-30TAG Series - Generation Index

4008-30TAG3 belongs to the Perkins 4008 range within the 4000 Series family. Per Perkins' official 4008-30TAG electric power engine documentation, the 4008-30TAG1, 4008-30TAG2, and 4008-30TAG3 share identical core engine architecture — configuration, cylinder count, displacement, bore/stroke, and compression ratio are the same across all three; the TAG suffix number differentiates power output level only (consistent with standard Perkins TAG naming convention).

Build List Identification Guide

The engine serial number (ESN) for this model begins with the prefix DGDH, which Perkins' official engine number records assign specifically to the 4008-30TAG3 (distinct from DGBH, used for 4008-30TAG2).
Please confirm your engine's Build List and ESN before requesting a formal quotation, as specifications and part compatibility can vary between builds.

FAQ

Q1: What is the fuel consumption of the 4008-30TAG3 at different loads?

At Prime rating, fuel consumption is 210 g/kWh at 110% load, 206 g/kWh at 100% load, 202 g/kWh at 75% load, and 204 g/kWh at 50% load.

Q2: Can multiple 4008-30TAG3 engines be run in parallel for higher output?

Multiple engines can be configured for parallel operation to increase total generating capacity; system design should be confirmed with the genset integrator or distributor for the specific installation.

Q3: What is the warranty coverage for the 4008-30TAG3?

Prime power coverage is 12 months with unlimited hours (or 2 years/6,000 hours for lower-utilization engines, whichever is sooner); standby power coverage is 3 years or 1,500 hours, whichever is sooner. Extended coverage is available through Perkins® Platinum Protection.

Q4: What is the difference between 4008-30TAG1, 4008-30TAG2, and 4008-30TAG3?

All three share identical core engine architecture (displacement, bore/stroke, compression ratio); the TAG suffix number indicates a different power output level, not a structural or emissions difference.

Q5: What are the most commonly replaced parts for the 4008-30TAG3?

Core wear items include piston assembly, connecting rod, bearings, cylinder liner, fuel injectors, and filtration components (fuel, oil, air) — see Common Replacement Parts table above; specific part numbers are confirmed via Build List and ESN.

Q6: What applications is the 4008-30TAG3 suited for?

This engine is commonly used in prime and standby power installations across manufacturing facilities, hospitals, and data centres, among other critical-power sectors.

Q7: Does the 4008-30TAG3 meet international emissions regulations?

Ratings for this model are optimised for fuel consumption and do not comply with Harmonised International Regulation Emission Limits; buyers in regions with specific emissions requirements should confirm compliance before ordering.

Q8: How do I decide between the 4008-30TAG3 and other 4000 Series models?

Selection should be based on required Prime/Standby kVA output and rated speed; confirm Build List and ESN with your supplier to match the exact configuration to your generator set design.
