t is possible that a 4bc1 Isuzu engine may fit in a Bedford Elf truck, but it would depend on various factors such as the specific model and year of the truck and engine, and any modifications that may be required to make the engine fit properly. It is recommended to consult with a qualified mechanic or expert in Isuzu engines and Bedford trucks to determine if this engine is a compatible and appropriate option for your specific vehicle.

If you are talking differential gear box is is SAE 90

The fifth generation Isuzu Elf appeared in July 1993, with more sculpted headlights.
In May 1995 it received a minor change, including upgraded, cleaner diesel engines.
An OEM deal with Nissan led to the Elf also being sold badged as a Nissan Atlas and a Nissan Diesel Condor 20/30/35 beginning at this time, followed by the Nissan Atlas Max from 1996 until 2000. The Atlas Max was based on the new, lighter duty Elf 100 (June 1995) which was available with a 2-liter petrol or a 2.5 or 2.7-liter diesel engine.[20]
In May 2004, subsequent to a few minor changes, the Elf underwent a more major facelifts with new, larger, trapezoidal headlamps.
Another OEM deal was forged at this time and the Elf was now also marketed as a Mazda Titan in parallel.
In Malaysia, this truck is manufactured by Heavy Industries Corporation of Malaysia (Isuzu HICOM Malaysia) under the name of HICOM Perkasa, but carrying the Isuzu N-Series Commando badge.

this you will have to investigate further . The gear box from a 2 tonner may be well down on the torque rating for a 4 ton truck and if they fit may not last because of the extra torque load on the shafts and gears . Best discuss this with the tech experts on the web customer technical services for the manufacturer if the truck

They are cast onto the drum.
