It's my understanding that 2.25L petrol engines fitted to military variants differed to civilian models.

I know that they had a 8-blade fan and a double pulley/fan-belt.

I have also seen the exhaust routed forward, ending at the front corner. (Though strictly this is not an ENGINE difference).

What else was different?

cheers

I understand that the front cover/water pump are different on "military" engines to allow the fitting of a large alternator.

However, to the best of my knowledge, this was NOT fitted to Australian military S2/2a Landrovers (as far as I know, all Australian military S3s used the six).

As you comment, many if not most had the optional eight blade fan, which came together with a tie bar on the bell housing to prevent the possibility of it's contacting the radiator. Some had an oil cooler, but again, this was a civilian option.

Some were fitted with a large alternator mounted on a bracket held under a couple of the head bolts, but again, like the forward exhaust, this was an add on, not an engine difference.

As far as I am aware, there are no differences between Australian military 2.25s and civilian ones, although you should be aware that there were significant differences throughout the production of these engines, and some updates were made during service - for example, my 2a has a Series 3 distributor.

The 2.25P in the army series 3 was esssentially the civilian engine with the double pulley and fan as you said.

The Australian army series 3 fleet only had the 2.6p six cylinder engine fitted.

The front exhaust modification was for workshop and radio vehicles only to keep fumes away from the operators at the rear of the vehicle.

As was stated by both JDNSW and Phoenix the series2/2a 4 cylinder motor in Aust Military use was basicaly the civilian version with the added extras of the 8 bladed fan, double pulley on crank and water pump, also generator (you can use a double pulley alternator) they also had an extended radiator shield, and heatsheild on the exhaust, a gearbox/engine steady bar from the bellhousing to chassis x member at gearbox, some special purpose vehicles,had an Oil Cooler-Firetrucks, and FFR's had a special mounting for the 24volt Radio Alternator fitted on extended Head bolts on some early Ser 2a's and I have seen one ex 131 Div Loc vehicle with the special front timing case cover which had the 24v generator mounting in it, the front mounted exhaust was fitted to Workshop trucks and some FFR's all had the coil bracket mounting on the right side of the cylinder block on a bracket held by the head bolts just after the distributor, this was done so that an engine could be removed/installed as a complete unit (connect-fuel,starter, rad hoses)and away you go.

cheers

G'day Folks

From an old MOD list of suggestions for disabling a Landrover

Place demolition charges against and detonate remotely.
Destroy engine by artillery fire.
