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 MGB or MGBF.
Nameplate fields to record before ordering:
· Build List (e.g. MGBF 8026 or MGB 8026)
· 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 1500rpm and 1800rpm versions?
They share the same Build List (MGBF8026) and parts, but are separate engine builds and are not field-interchangeable between speeds.
Q2: Are genuine Perkins parts required, or can aftermarket parts be used?
Genuine parts via an authorized first-tier distributor ensure correct fitment and preserve warranty validity; aftermarket parts carry fitment and performance risk.
Q3: What lubricating oil is specified?
15W40 to API CI-4.
Q4: What does the ElectropaK configuration include?
A complete generator-set engine package incorporating mounted air filter, loose-supplied radiator with integral air-to-air charge cooler, 24V starter/alternator, and ECM-based engine protection.
Q5: What fuel specification is required?
BS 2869: Part 2 1998 Class A2, or ASTM D975 D2.
Q6: How does fuel consumption compare across load levels at 1500rpm?
Standby 207 g/kWh (114 l/hr); Prime 211 g/kWh (106 l/hr); 75% load 215 g/kWh (81 l/hr); 50% load 220 g/kWh (55 l/hr).
