Hello,

Any suggestions for a more modern substitute for the Lucas C40
generator? This is for a 1960 Series II 109" I'm up for fabing a new
mounting bracket/arm.

Or is there a source for reasonably priced rebuilt C40s in the UK?
I can live with the 22 Amps.

I'm in the States.

Thanks

Jay

just replace it with an alternator there is a website with the details at
http://www.lrfaq.org/Series/FAQ.S.alt_alternators.html
when you say rebuilding a C40 the only thing I have needed to do (in the
distant past mind you ) was replace the brushes and clean up the commutator
to bring it back to health unless maybe you have a more knackered item its
definately a home workbench job

Get the cast alternator mounting bracket off a later engine (it will fit
straight on) and fit a Lucas 17/ACR alternator. You can use the same wiring,
it's very easy to change, and do away with the dynamo control box (all the
regulation and diodes are self contained in the alternator). I've got a
reconditioned (old stock) dynamo on the shelf that you can have cheap but I
don't know how much it would cost to send to the States, failing that you
should be able to fit something off an American car with a bit of ingenuity.

Lucas 17ACR will fit straight on with the mounting brackets from a
Series II. But you have to take the crankshaft pulley off the engine
to change the top bracket - the bolt is behind it

Alternator mounting bracket - 574855 ( 5/16" U.N.F thread)
Superceded by ETC4357 ( 8mm x 1.25mm thread) either will fit.

Alternator - RTC5083 E

Dynamo - RTC3840 E

It is possible you can easily repair your C40, although in my experience
they usually fail by the bush at the back end wearing due to poor
lubrication or dust ingression and resulting poling and burning out the
armature or field or both.
It should be possible to find a straight replacement for it in the US from
generator equipped cars of similar vintage, but most people replace them
with alternators these days. The most direct suggestion would be to source
the parts (numbers given by other posters) from one of the UK posters that
advertise in the Landrover Magazines.
You can fit any alternator that is physically more or less the right size
even if you have to fabricate a bracket rather than import one.
Another suggestion would be to contact a US specialist such as Rovers Down
South in New Orleans.

worth peripheral note that the very early 2¼ engine won't take an
alternator, or so I understand from someone who failed to fit one. Something
about the mounting for the dynamo being part of the crankcase casting.

I think you will find it's the same as the late engines, the long bolt
threaded into the alternator bracket goes through the block whilst the two
bolts at the front will need slightly longer ones of 5/16" U.N.F thread up
to the Series 3 five bearing engine when they changed to M8 x 1.25,
depending where you got the bracket from you could end with U.N.F in the
block and M8 in the bracket (check the holes first)

I'm only going by what I was told. This is something like 1959 engine, and
it's not the same as a later SII one that the same chap had.

Im sure you could fit an alternator to any engine if you were
determined enough!
Me and a mate managed to fix a pulley driven vacuum pump to his 2.25D
to power his brake servo. There are plenty of bolts you can use for
fixings and i think i welded up a simple angle bracket for the back
mount.

Early Series 2s had the 2 litre overhead inlet and side exhaust valve
engines, they probably meant those, but they had the dynamo mounted at the
top right hand side of the engine, but AFAICR the early 2286cc engines with
engine nos. starting 15........ had the small crank and different block but
the dynamo mountings were the same as later engines as were the early 2
litre diesels. Even the 200 Tdi has that lump cast on the block, it's not
drilled but could be.

AFAIK it's a 2286. If the bloke's still got it I could have a look one day.
