Series III to Series IIA Swaps

[Jock The Rock]

Gday

I am interested in upgading this Series IIA, if I end up buying it.

I'm interested to know if a Series III diesel will bolt in easily? (apart from fuel lines etc) I am under the impression they are almost the same block?

Also will an overdrive swap over from a Series III gearbox to a Series IIA gearbox?

While on the subject will a PTO unit off a IIA fit onto an LT230 Transfer case? (1995 Defender)

Thanks

Jock

i have been told that the pto cant go on the defender

[isuzutoo-eh]

From what I understand:
same block for both 2.25D and 2.25P, so mounts are the same and bellhousing fits to gearbox the same.
The overdrive goes on the transfer case which is the same for both
Don't know about Series PTO to LT230
I'm curious as to why you think it needs upgrading, when you have a perfectly good and well set up Defender for long distance and tuff trips?

Sounds good

Why you say? Because the Defender has spent the past week and a half on jack stands in the carport

I can get hold of an overdrive almost for free and I'd like to have a go at rebuilding a 2.25D anyway

If I bought it, it would be as a spare. I'm a diesel apprentice and personally I'd prefer a diesel engine. Fuel economy, engine braking (without backfires :p ) , less things to go wrong and I know more about diesels than petrols :)

I love the series diesels, they are absolutely bullet proof and a nice little engine. Couldnt think of a better combo than a series 2 shorty with a diesel and overdrive.

[Lotz-A-Landies]

The series IIa & SIII petrol and diesel blocks have the same part numbers!
The bonneted control series, LT95 and LT230 all have their own individual PTO which aren't interchangeable.
The bonneted control series, LT95 and LT230 all have their own individual overdrives.
The most reliable bolt-in overdrive is the Roverdrive, a Roverdrive for the LT95 will most likely be available in September.
There is no overdrive for the Series forward control/1 Ton box.

Virtually all mechanical parts are fully interchangeable betweeen the Series 2, 2a and 3, and almost all the parts are NOT interchangeable with the later coil sprung Landrovers.

I'm wanting to do something similar with this 2a shorty:http://www.aulro.com/afvb/series-2-2a/103020-late-2a-farm-find.html#post1232086
and one of the diesels from this haul

...not with the overdrive, though.

If you are going to go a diesel and you want to drive in on the road you WILL wish you had an overdrive......

Looking at what isuzurover did with his diesel would suggest otherwise. Seemed to be fairly simple tweaks that made it go like a petrol. Then with the reduced weight of the shorty should further improve performance. Maybe an electric fan..

[series3]

I was thinking the same thing korg, an electric fan would be a good addition to a 2.25. But, the downside would be water crossing would be all but out the window.

Not ever owning a 2.25 diesel i was only guessing at how they go in standard form. Silly me..........

[korg20000bc]

I own a diesel engine but have never driven one. My knowledge is almost limited to what other people have written on the site here. One fellow who I chatted to, he used to own a 4x4 dealership, told me that the diesel wasn't that bad but they weren't an engine that the average Aussie understood ie. its strengths and weaknesses.

Would that be a big limitation? A water crossing should be cooling to the engine anyway, shouldn't it? I don't really know exactly how they operate but I understand that they only come on when required for cooling.

[series3]

I was thinking more along the lines of the electric fan's water intolerance, a water crossing would ruin it, and leave you without a fan afterwards. If that makes sense

[akelly]

My fan's only a cheapy, but its a sealed unit - as long as you mount the thermo switch (which is not sealed) up high you should be right. Think of the fans on most modern fourbys, for the AC etc..., they are all electric and stand up to water crossings just fine.

Much better than a fixed fan, which can be dragged forward into the radiator if submerged (they act like a propeller on a boat). An electric fan is a definite (but minor) improvement on HP and fuel useage.

i personally would not put a 2.25 diesel in a series lany, in my serirs 2A i have a 2.8 6 cyl nissan motor, like a dream. i keep reading that you ausie guys dont like overdrives, if you fill them with the proper oil instead of tha old amber nectar they work great. mines not noisy at all and works like a dream.as for the fan, i have an a/con one on my rad with a temp switch also in the rad, when it reaches 86 degres the fan comes on , also works a treat, in water as well, dont just use it for shopping. by the way, a series 3 o/d will fit a2A.

[UncleHo]

G'day Folks :)

The Landrover series 2.25 diesel motor will only give you about 80kph max as it was designed as a work motor and not a road speed motor, they did not come until the 200TDI, they are lower HP and are slow revving, that is why an O/drive is almost essential to get acceptable road speed from a 2.25 diesel.

ive always disconnected the electric fan on my patrol through deep water crossing as they tend to snap blades when trying to turn water

fair enough - mine can freewheel if something gets caught or whatever, I cant remember what brand it is but it was only a cheapy.

Thanks for the replies

I've since decided not to buy aother Series Landy, but spend my money on the Defender and Series I instead

Just interested to know though

Will a IIA steering box fit in a III?

Thanks

The post 1967 2a steering box is very similar to the Series 3 one although the part numbers are different. Although the turn indicator centering mechanism is different, and most Series 3 have a steering lock, I am guessing that with a little work they are interchangeable.
