Perkins 2806A-E18TAG2 ElectropaK Genset Engine – 625–700 kVA

The Perkins 2806A-E18TAG2 is an 18.1-litre, six-cylinder ElectropaK diesel engine for prime and standby generator sets. As part of the wider Perkins generator-drive engine range, it uses parallel turbocharging, air-to-air aftercooling and direct injection to deliver high output from the Perkins 2800 Series industrial platform.

Build List JGBF8028 / JGB8028 covers separate 1500 rpm and 1800 rpm factory builds. The 1500 rpm version is rated at 650 kVA prime and 700 kVA standby for 50 Hz applications, while the 1800 rpm version is rated at 625 kVA prime and 687 kVA standby for 60 Hz applications. These are not field-switchable speed settings, so the required frequency, rated speed, Build List and complete Engine Serial Number (ESN) should be confirmed before ordering.

Perkins 2806A-E18TAG2 Technical Specifications

Power Ratings at 1500 rpm and 1800 rpm

The two rated-speed versions have different generator outputs and must be selected according to the required frequency and duty. The table separates gross engine power, net engine power and generator output so the correct build can be approved before quotation.

Choosing the Correct Rated-Speed Version

The 1500 rpm build is normally selected for 50 Hz generator systems and provides the higher output of the two versions. The 1800 rpm build is intended for 60 Hz systems. Both fall under the same Build List family but remain separate factory configurations, so changing the genset frequency does not make the engines interchangeable.

At 100% prime load, the stated fuel consumption for both versions is 202 g/kWh. At 50% load, the stated figures are 201 g/kWh for the 1500 rpm build and 210 g/kWh for the 1800 rpm build, indicating a difference in partial-load efficiency that may matter in variable-load applications.

Build List Identification and Configuration Matching

JGBF8028 and JGB8028 refer to the same 2806A-E18TAG2 specification. JGBF8028 is the original Perkins designation assigned in 2009, while JGB8028 is the updated designation used for later production batches. The designation change relates to the production batch; parts compatibility remains the same across both Build Lists.

Information to Record from the Engine Nameplate

The Build List appears on the engine nameplate, normally mounted on the rocker cover or timing case. Record the following information before requesting an engine or replacement-parts quotation:

• Build List: JGBF8028 or JGB8028
• Complete Engine Serial Number (ESN)
• Required rated speed: 1500 rpm or 1800 rpm
• Required generator frequency: 50 Hz or 60 Hz

The Build List identifies the base specification, while the ESN identifies the individual engine build. Both should be provided so the supplied engine configuration and replacement-part references can be checked before order commitment.

Replacement Parts for JGB/JGBF8028

The following original Perkins part references are listed for the 2806A-E18TAG2 Build List JGB/JGBF8028. Additional Perkins engine parts can be reviewed by category, but the complete ESN is still required before confirming an exact part number for an individual engine.

For planned cylinder-head and valve-train work, the Perkins KRP1546 top overhaul kit for 2806 TAG1/TAG2 engines is a related repair reference. Its contents and suitability for a specific JGB/JGBF8028 engine should be verified by Build List and ESN before purchase.

Procurement, Export and Delivery

Engine availability and final pricing depend on the selected rated-speed configuration, order quantity and delivery terms. The typical lead time is 3–4 weeks, and the stated quotation time is within 24 hours after the required configuration and commercial information have been received.

Warranty and After-Sales Support

The stated warranty period is 12 months or the manufacturer-specified operating hours from the commissioning date, whichever comes first.

Warranty Exclusions

1. Damage caused by incorrect installation, improper commissioning or failure to follow the Perkins Operation and Maintenance Manual applicable to JGB/JGBF8028.
2. Normal-consumption items, including filters, belts, coolant and lubricants.
3. Damage caused by contaminated fuel, an incorrect lubricant specification or neglected cooling-system maintenance.
4. Modifications or repairs completed by non-authorised personnel during the warranty period.
5. Transit damage not reported within three working days of delivery. The shipment should be inspected on receipt, and visible damage should be recorded before the delivery receipt is signed.

Warranty Claim Process

1. Document the fault: Record the complete ESN, operating hours, fault symptoms and photographs of the affected area.
2. Submit the claim within the warranty period: Send the documentation by email or WhatsApp and include the ESN in the subject line.
3. Technical review: The engineering team reviews the submitted information within two business days and advises on the probable cause and next steps.
4. Confirm the resolution: Depending on the assessment, the response may include replacement parts, coordinated repair support or an engine exchange. The proposed resolution is confirmed in writing before action is taken.

Photograph visible damage before unpacking, record it on the delivery receipt before signing and notify the supplier within three working days with supporting photographs. Do not commission a damaged engine before the damage report has been completed.

Perkins 2806A-E18TAG2 FAQ

What generator output can the 2806A-E18TAG2 support?

The 1500 rpm version is rated at 650 kVA prime and 700 kVA standby. The 1800 rpm version is rated at 625 kVA prime and 687 kVA standby. The required version depends on the genset frequency and approved operating duty.

Should I order the 1500 rpm or 1800 rpm version?

Select the 1500 rpm version for the specified 50 Hz configuration and the 1800 rpm version for the specified 60 Hz configuration. They are separate engine builds and cannot be converted between rated speeds in the field.

What is the difference between prime and standby ratings?

Prime power is intended for variable-load operation under the permitted prime-duty conditions. Standby power is the higher emergency rating and is subject to the annual operating-hour limits defined by the applicable engine duty classification.

Does the 2806A-E18TAG2 meet regulated emissions standards?

The “A” designation identifies a Fuel Optimised, non-emissions-regulated build. Buyers in markets requiring EU Stage, U.S. EPA Tier or other mandatory emissions compliance should confirm local requirements before purchasing.

Is a single customer-interface wiring harness included?

No. The standard ElectropaK build includes connector wiring to the engine ECM only. A harness integrated to a single customer interface is not included as standard.

How should the correct engine and parts configuration be confirmed?

Provide Build List JGBF8028 or JGB8028, the complete ESN and the required rated speed. These identifiers allow the engine specification and replacement-part references to be checked against the original build record.
