Crankshaft pulley for a BMC 1.5 diesel
Fredxx
Given this diesel engine is a variant of the B-series 1500 engine, are there
any "compatible" pulleys from the other Austin/BL/Morris range?
Andy Breen
These engines are /amazingly/ common in marine use - usually under the
Thorneycroft or BMC label. Might be worth trying a marine engineer,
though be warned that any component in marine use will be more expensive
than the equivalent bit in any other use..

The engines are very common in the narrowboat scene but the pulleys don't
seem to be or command a high price. I was hoping to hear anyone's
experience of compatibility as I've heard conflicting stories.
Many thanks for your reply.

a crank pulley on a B Series begin to fail - the rivets holding the pulley
to the boss came loose.

They also have a harmonic balance. My MGB has one and the Austin 1800 etc

Any chance the OP could give us the measurements of the pulley? A photo
might be helpful. My thinking is that this must have been a pretty standard
item, or made up from standard bits - I'd be very surprised if this was a
"custom made" part for this one particular application. Also, what happened
to the original one? Was it missing from your engine, or as Dave hinted,
perhaps the rivets have come loose - in which case it is repairable. Let's
have the back story!

The crankshaft pulley on the BMC 1.5D appears a solid affair with a heavy
mass of metal in front of the v-pulley. It doesn't appear to incorporate a
rubber damper I've seen on some A-series engines. I've never worked on
B-series before and so have no idea what variants are available. There are
no rivets.
The reason I need one is because I don't want to disrupt the current use of
the engine whilst I try and fit a second alternator to the engine.

Just had a look at a photo I have and I believe it does have a damper which
accounts for the "heavy mass"!!

The rubber in the damper is not readily visible on those tts only thin.

Did you say this because of the price of a new unit from Moss?
The one on my B is still original and that's 1962.

They're not really a service item which can push the price of new parts
up.

I would say that if I needed one, could have a good second hand item
within 1/2hr for 5 bucks. Those in the Moss catalogue at that price are
exorbitant. My guess is they are a lot cheaper here, over the counter
from the manufacturer in Melbourne or even a MG parts specialist. Moss
are a bit over the top.

It's likely the Moss item is re-manufactured?
New damper pulleys for my SD1 cost quite a bit too - but are cheap
secondhand.
Later B Series engines certainly had them - but then that engine was a
substantial development of the earlier one with larger crank bearings,
etc. Dunno if the crank pulleys are interchangeable.
But I also dunno anything about the diesel. Given the original B Series
would break cranks quite readily, it could be it has a stronger one.

My B is a 1962 which was #650 off the production line and that has a
balance.
Parts listing for the MGB tells me they had three pulleys, early, then
thru to 74, then 18V 75 on. The picture is showing a balance.
I didn't know that there was a diesel either.

The 'B' is of course pretty well the last variant of the B Series. (I know
it changed from 3 to 5 main bearings) And being the biggest is more likely
to need a vibration damper.

I wonder if there were more pulleys for things like air con? The power
steering pump on the 1800 was driven off the dynamo. Dunno if the Marina
offered such things. Or if one was ever stuck on the back of an
alternator.
> I didn't know that there was a diesel either.
I knew it existed, but that's about all. Think it was based on one of the
1600cc versions?

In the earlier days it was a 1.5 diesel and later on it was based on the
1622 block presumably they ran out of 1500 blocks.
Early A60s and Morris Oxfords had diesel engines mainly taxi drivers wanted
them.
If looking for spares remember these engines were fitted to the vans as well
like the J2,J4 and the Sherpa. The Post Office had loads of them. We always
used to wind up the snobby MGB types by referring to the MGB as a two seater
Sherpa!.

Only the 1800 version changed to 5 main bearings. The 1500 stayed with just
3!

I thought the 1600 was a different engine again? The sizes of diesel engine
I'm aware of in common use are the 1.5 and 1.8.

There are probably as many working BMC B-series diesels in use as petrol
variants. Except they tend to be confined to the narrowboats and other
marine applications. They are regarded as a pretty good workhorse where
parts are more available than other engines such as Perkins.

What about the 1600 variants that went into the later MGAs?

I recall reading somewhere that one fundamental limit of the engine was the
stroke of 89mm which was set by the position of the camshaft.

Both 3 bearing. There were three different 1600s fitted to the MGA if you
include the twin cam. IIRC, the 5 bearing was developed mainly for the
'Land Crab' 1800 saloons.

That's because it was *replaced* by the larger variants. It was overbored
to 1588 then a major redesign to 1622 with a larger crank. The 1798 a
development of that - before getting 5 main bearings. Although two sizes
may have been available at the same time, the 1500 was dead and buried
long before the 5 bearing came out.

Basically a B Series.

I recall that Car magazine tested a Morris Oxford (Farina) diesel. The
picture was of a Farina, covered in cobwebs and apparently in a scrapyard.
Part of the text was "I started it up, and omigawd the bigends have gone".
The good days when the irreverent Aussie Doug Blaine was editor.
