series gearbox

Yes it will fit - gearboxes are the same for petrol and diesel series

3's.

Except the Stage 1 V8 & 3.9diesel which have a different gearbox. JD

A 3.9 diesel?

4BD1 Isuzu was offered here in Australia in the Stage 1's

You learn something new every day ... especially where Land Rovers are concerned. Happy New Year :-)

On or around Mon, 02 Jan 2006 10:20:34 GMT, SteveG enlightened us thusly:

bloody shame that LR didn't do that more widely. If they'd had a credible diesel option sooner (and it really did in the old days come down to capacity) there would've been fewer people buying jap 4x4 trucks, I reckon.

The 2.1/4 diesel was proabbly not bad when they first put it in the truck in

1957. by 1967 it was starting to look slow and by 1977 it was definitely out of date. Continuing it's use up to about 1987 was just silly (not quite, I know, the numbers were nice).

The 2.5 NA diesel that replaced it wasn't fantastic either, just better than the 2.25. The addition of a turbo for the 2.5TDi was a lot better.

It was useless from the start, a petrol engine cobbled up with a distributor pump to allow farmers to use a common fuel. Even then it had the worst specific fuel consumption for any diesel of the period.

Yes but at least it acquired a decent injector pump, still absolutely gutless and an embarrassment to drive.

They put the turbo on the earlier 2.5 first, it actually went ok but there were some engine problems which I believe they gradually sorted. I drove a 1985 one with an aftermarket intercooler and quite liked it.

LR diesels didn't get useful till they got coil springs as well.

AJH

It wasn't. It was provided as 2litre (2052cc) diesel first, along with the existing 2litre IOE petrol. It was then enlarged to 2286cc and provided as either petrol or diesel. Commonality of parts between the two engines meant that landrover could save on costs, as the bulk of the engine parts are the same.

The differences are the head, camshaft and pistons/con rods, and what you fitted to the camshaft - dizzy or injector pump.

Alex

Yes, the engine was originally designed as a diesel - the petrol engine is the conversion (which is why the petrol engine is so resistant to abuse). And you have to remember that diesels this small were very scarce in the fifties, even the late fifties (which is why Rover designed their own). But the power available was inadequate for many markets right from the start - even the 2.25 petrol was low powered compared to competition (not that there was very much in the fifties). At the end of the fifties the Landrover was beginning to face competition from the Landcruiser, which, while it had only three gears, and appalling steering, and numerous other shortcomings, had 50% more power than the 2.25. Also coming on the scene was the Patrol, also with many shortcomings, but with a version of the BMC 'C' series engine around double the power of the 2.25. But also note that neither of these companies offered any diesel engine at all on their four wheel drives until around ten years after Landrover. JD

That's news to me, I thought the 2286 engine first appeared in 58, I had one in 644 FAR, about 69. The diesel didn't appear till 61. I was unaware of an earlier diesel.

Yes this is a good point, they tried the same with the B40 and Champ.

Yes but it was still an awful diesel.

Again I didn't know this, have you a reference? I used to have a book on engines (by LJK Setright I think) and it had comparison charts in the back, I distinctly remember the Rover's poor performance.

Agreed there then!

AJH

The 2286 petrol engine appeared in 1958, but the diesel in 2.0 litre form over a year earlier, to be replaced by the 2286 diesel in 1961. The two diesel engines are essentially identical except that the 2.0 has wet sleeves with an increased bore for the 2286. Both the diesel and petrol engines were probably running in prototypes as early as 1955, and the basic design work presumably dates from the very early fifties.

Perhaps not brilliant, but there were practically no other comparable diesels from the fifties at all. The Mercedes is the only one that comes to mind. Other similar capacity engines were much heavier and lower power.

Refs. For example: The Landrover Story, James Taylor 1996 ISBN 1 85520 3391 p.69 describes how the Landrover wheelbase was increased by two inches in early 1956 to accommodate the new engine, which was introduced fairly late in 1957 in the 2 litre wet sleeve diesel version. The petrol version did not appear until 1958 and the 2.25 diesel until 1961.

Another reference is: The Landrover, Graham Robson 1976, ISBN 0 7153 7203 3 p.38 describes the introduction of the 2 litre diesel in June 1957 and the introduction of the 2.25 petrol engine in 1958 is described on the following page.

I don't think so! The early 2286 petrol engines had much smaller crank journals and had the same short (top to bottom ) timing case as the 2 litre diesel. On the later 2286 engines from about '65 with the bigger bearings the crankshaft was cast iron on the petrol and forged steel on the diesel with the same size bearings for both. Also the water pumps were different along with the timing case and head castings. You can tell the early blocks by the size of the side core plugs as well

I'm sure you mean '59 not '69, that would be the small crank version which didn't last long.

Now thats a new one on me, a diesel Rolls B40.

And crankshaft. And flywheel.

No it wasn't, it was absolutely reliable and if you ground the camshaft, lightened the valve gear and cam rollers, polished the con-rods, balanced the crank, upped the injector pressures and played with the timing it would equal if not outperform the petrol version and still return 25 m.p.g. Marvellous in those days. What nostalgia!

Disagreed ;-)

Martin.

No I meant I had it first in 69 by which time it was 11 years old.

No the B40 shared lots of bits with the B80 which was in army service, I think the ferret had common parts too. So the champ was designed with it to appeal to the army, made it expensive.

fairy nuff

AJH

Sorry, I misunderstood, must learn to read properly!

And the Humber Pig, with a B60 version I think, correct me if I'm wrong, and yes I see what you meant.

Absolutely ;-)
