Series 3 2.25 petrol engine into Series 2a?

[drfish]

Hi, this is my first post...

I am in the early stages of a restoration of a 1970 Series 2a 109. I was curious as to whether Series 3 engines (engine #902..., c. 1978) will just bolt straight in to a Series 2a. Also, are the clutches the same between the late Series 2a and the Series 3?

Thanks in advance for your help-

no the 2A non syncro box has a different clutch to the 3,

that said the flywheels are the same so you just bolt the 2a clutch onto the 3 motor and you're away.

If you are swapping over accessories, the S3 has an alternator and the S2a has a generator, so the brackets will have to swap as well if you want to keep the generator (I'd fit an alternator).

The early S2a had an exhaust manifold with the pipe outlet facing up, but the manifolds are interchangeable.

Thanks Dave and John, just the info I was after.

oh and if you keep the SIII carbies and intake manifolds dont forget they are setup with emissions control stuff on the later ones.

It may depend on what the previous engine was in the 109. If it was a four cylinder there wont be much difference and you can use whichever clutch setup you prefer. I personally would use the early clutch setup.
If your 109 was a six cylinder the bell housing and the panel behind the bell housing are different, but may have been changed already.
I think the engine mounts are the same but you may need a spacer on the drivers side.
Most bits will swap over but there will be a few small bits you need.

Thanks Ian, there is currently a 4 cyl in the 109, runs very smooth but heavily worn, so I thought it would be a pretty clean swap.
Was the spacer on the mount only required if it was formerly a 6 cyl?

I am not sure if the 6 cylinder had the spacer on the drivers side. My series 3 had a Holden engine in it and the 2.25 i removed from an old series 3 was missing the spacer. I was wondering why the enigine wasnt sitting straight and the engine mount was under tension at a strange angle.

I found a spacer on AULRO and the problem was solved.

Hi Guys,
I am doing a complete rebuild of my 1963 series 2a (owned since 1965). I have located a very good very late landrover 2.3 2 bearing petrol 4 cylinder engine, 11H number on the block. Can I just drop it in, or do I need to change the flywheel and housing to an earlier one to get it to match?
Over here everybody seems to be using TDI 200 for this, but i would like it to be something like the original,

Best Regards
Mike

As far as I am aware all the 2.25 engines will interchange without issues except as noted above. Series 2a was fitted as standard with the smaller clutch, but the larger one is a straight replacement (and optional, so you may already have it). The late engine flywheel may not be drilled for the smaller clutch, so use the larger clutch, but note that the clutch cover (pressure plate) is different from the S3 for the 2a, having a spacer on the release fingers. Just a matter of buying the right part, and you probably want to replace it (and the driven plate) anyway while the engine is out.

John sometimes I can be a bit thick but would I be correct in assuming from your post a 9.5" clutch plate will fit behind a three finger type 9" pressure plate with top hat type release bearing........asking because I've inherited from PO's several new 9.5" clutch plates but no 9" if I can use them on my 2a it would be good

Cheers Paul

No. The 9" clutch has the three finger clutch cover with coil springs, the 9.5" has a diaphragm type clutch cover with lots of fingers that is similar to the S3 one, except that it has a spacer ring over the fingers to match the S2a withdrawal sleeve. But your old S2a flywheel should be drilled for both types, although the S3 flywheel may only be drilled for the larger one.

I hope that is clearer!

Thanks John the engine/flywheel is a Holden and has only been drilled for a 9" as far as I can tell will have a look later

Cheers Paul

I think if you are putting in a Landrover engine - use the Landrover flywheel! And the 9.5" clutch is preferable as well!

Whoops I didn't make it clear the engine in question is a Holden 202
