Build List Identification Guide

The Build List is stamped on the engine nameplate, mounted on the rocker cover or timing case. Locate the dataplate and read the alphanumeric string beginning with TGA or TGAF.

Nameplate fields to record before ordering:
· Build List (e.g. TGAF5004 or TGA5004)
· Engine Serial Number (ESN)
· Rated speed (1500 or 1800 rpm)
Provide both the Build List and ESN when requesting a quote. This allows us to confirm exact specification match before order commitment.

FAQ

Q1: What is the difference between the 1500 rpm and 1800 rpm versions of the 2806A-E18TAG1A?

Both share Build List JGAF5004 but are separate, non-field-switchable builds with different rated power and kVA output. The 1500 rpm version is rated 600 kVA Prime / 660 kVA Standby; the 1800 rpm version is rated 625 kVA Prime / 687 kVA Standby.

Q2: What does the "A" prefix in 2806A-E18TAG1A mean for emissions?

The "A" prefix indicates a Fuel Optimised, non-emissions-regulated build, distinct from regulated tiers used in other markets.

Q3: Why does this engine use parallel (dual) turbocharging?

Parallel turbocharging with air-to-air aftercooling gives the 2806A-E18TAG1A strong power density and more consistent output at high altitude compared to a single-turbo equivalent.

Q4: What is the fuel consumption of the 2806A-E18TAG1A?

At Prime rating, fuel consumption is approximately 199–203 g/kWh across 50–110% load at 1500 rpm, and approximately 201–210 g/kWh at 1800 rpm.

Q5: Does this engine come with a wiring harness pre-integrated to a single customer interface?

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

Q6: How do I confirm the correct Build List and configuration before ordering?

Provide the Build List (JGAF5004) along with the engine's ESN, which can be cross-checked against the original build record before quoting.

Q7: Is the 2806A-E18TAG1A available in an Electro unit configuration as well as ElectropaK?

This model is currently supplied only as ElectropaK; no Electro unit variant is offered under Build List JGAF5004.

Q8: What is the lead time and how do I request a quote?

Standard lead time is 3–4 weeks from order confirmation, with a quote provided within 24 hours based on configuration, quantity, and delivery terms.
