Series 2 possibly a 2.5 na? help

please can any one help.
i am now the proud custodian of a bit of a mixed up landrover series 2a. The previous owner is no longer with us so i cant find out any history .(diy tree surgery)
series 2a body with a series 3 front wing, galvanised chassis, series 3? gear box i think because the slave cylinders rubbers packed up and on examination of the replacement seemed to belong to a series 3.
and what i believe is a 2.5 na engine but i'm not entirely sure as some of the front end components are different to all the pics available on the internet. ie the timing belt has an extra pulley and does not require the lower flywheel to be removed their is also a machined hole in the timing belt cover so you can see the cam pulley when in place . see below any ideas please.

Taxi engine? FX4S? The timing case being exposed like that suggests it's not for a vehicle designed to go wading up to one metre.

What does the serial number start with? It should be found on the the near side under the cam shaft inspection plates.

i know what you are going to say its not even a london taxi engine its a sherpa van engine ?

good job it was cheap

Used to use a sherpa 2.5 diesel in my series 3 went well but removed to fit 200DI.
Timing belts where getting hard to get .
Have a copy of the manual if your going to keep it PDF format.
Timing case off a 12J can be swapped onto the engine block as same block.

Yes I've been reading a historic threads and they noted that parts where hard to get but after sitting in an orchard for 2 years with only sheep for company all it took was half a gallon of water and an hour on charge and it started and ran a little bit of smoke but nothing horrible

The idea was to get it up and running as is and then decide . The chassis was replaced a few years ago with a galvanized one and it seems it was designed to fit the 2.5na as nothing has been cut or altered there was never a battery tray or air filter fitted so i think a 2.5 na standard landrover engine would be my first choice as replacement

I think so. Sherpa van engines are 14J or 15J.

I probably don't have to tell you it is missing a few bits.

No modification is required to fit a 2.5 NA in a standard Series 2a chassis. So you would have the option of going back to two and a quarter engine if you want.

The only bit i i haven't got is the fan but i take it that a standard viscose fan of a landrover 2.5 na will fit

If there is a threaded shaft on the front of the water pump , it should screw on to that. There should be a fan cowl as well, but you might get away without that for testing runs.

Yes the threads go the wrong way on the water pump so as it spins it tightens and we have a 2a rad with the old metal cowling standard 2.5 thermostat housing with original series 2 top so it fits the top hose

You should be able to cobble something together with that.
In the longer term, if it was mine, I would go back to two and a quarter. As @Blackburn said, parts for 2.5 are hard to come by now.
Two and a quarter is more original to your vehicle, and has a timing chain instead of a belt.
If you aren't going to do masses of miles, I would go petrol a well, bit more power than the diesel, and a less stressed engine.

Yes i totally agree my son is trying to convince me that a 200tdi is the answer but that's to complicated for me i have owned 3 landrovers over the years 2 petrol and 1 diesel all 2.25 all series 2 and 3 and by far the best was the petrol so will probably go with the petrol in the end but if i can get this old girl mobile it will do for the time being

Some like 200 Tdi, or 200Di, the same with the turbo removed.
I like to keep a Series as original as possible, and I don't much like the diesels, Land Rovers originally had petrol engines, and I think they work best, although many disagree.
I have had quite a few Series myself, 2a s and 3s, and a Ninety. I think petrol 2a was my favourite.

Totally agree although my last was a series 3 brown petrol county its is still about because i check the reg number on the dvla LMB80Y sold it when my son was only in his cot now hes 29 20 stone and 6 foot 6 where have all the years gone wish i still had it

Wish I still had a few of mine, but my back would be even worse if I had!

Late 2A's had headlamps in the wings, just to confuse you, it was not uncommon to 'upgrade' and have 4 headlamps as a result

That's not really true....the drivers side engine mount on the chassis needs cutting off and repositioning (the favourite thing to do is use the engine bracket from a series engine turned upside down and welded to the chassis) but the passenger one can just have the engine bracket turned upside down to fit on the same chassis mount.

You're better off using a metal series fan as the plastic one will stick out into the rad.
