Hi all,

Is anyone able to assist with filling in gaps or making corrections in the below list of engine numbers? All are from early 1970s in the 1000 and 1200 series.

The info so far has come from various sources, including PUB1052, bulletins, TME/BMCE, John Sneddon's book, Ausmini, and anywhere else I could find. I don't have any late 70s factory documents that reference the numbering system once it was complete - only at its introduction.

All input and feedback greatly appreciated.

1098cc
1000 – 1098cc for Mini 1100 and Van
1001 – 1098cc for Clubman, Leyland Mini and Mini S
1002 – short engine replacement for 1000 and 1001
1003 – low compression option for 1000
1004 – low compression option for 1001
1005 – short engine replacement for 1003 and 1004
1006 – 1098cc for Moke with rod-change gear box
1007 – 1000/1001 with rod-change gear box
1008 – 1006 with drive shaft change (‘pot joints’)
1009 – 1007 with drive shaft change (‘pot joints’)
1010 – 1009 with diff ratio 3.44;
1011 – low compression option for 1009 (rod change and pot joints)
1012 – low compression option for 1010 (diff ratio 3.44)
1013 – (?)
1014 – (?)
1015 – ADR27 compliant for Mini, from January 1, 1974
1016 – ADR27 compliant for Moke, from January 1, 1974 (???)

1275cc
1200 – 1275cc for Clubman GT
1201 – short engine replacement for 1200
1202 – (?)
1203 – (?)
1204 – 1275cc for Moke Special Export (Californian)
1205 – 1275cc for Clubman GT (Police)
1206 – closed chest version of 1200
1207 – closed chest version of 1205
1208 – short engine replacement for 1206
1209 – short engine replacement for 1207

Many thanks,
Evan

EDIT: List updated with new information from gtogreen1969, winabbey and rodmac. Updates in blue.

This will fill a few gaps.

1206 was fitted to the 1973 Clubman GT (1100S type block without tappet covers.)

This is from a later version of the Mini parts fiche as posted by gtogreen1969 above. Has a couple of extra 1275 prefixes.

Looking at the descriptions I would assume the 1207,1208 and 1209 were non S blocks like the 1206.

Not sure if they were ever produced because most of the 1973 GT's went to NZ and by that time the cops were moving to Toranas.

Thank you very much gtogreen1969 and winabbey, that's incredibly helpful. I've updated the original list with the new info in blue.

I included 1013, 1014, 1202, and 1203 for sake of completeness in the series, but no idea if they actually existed. Interested to hear from anyone who has engines to confirm info on the list for any of the less common numbers too.

Couple of reference questions: is that first list from simply "PUB 7", and does the microfiche have any date or publication number to reference?

Thanks,
Evan.

Also, have you come across anything on the Moke engines, namely 1008 and 1016?

I'm assuming they were introduced with similar changes to the Mini engines but I can't confirm (e.g. drive shaft and ADR27 changes).

Here is the breakdown of the combination code numbers used on later engines. Most likely stolen from one of Winabbeys previous posts.



I haven't come across any of the other ones you are missing. Sorry

Both PUB 7 and PUB 23 (the one I posted) are microfiche. PUB 7 is Aug 1977 and the other undated but later.

Here's another page from PUB 23 that shows vehicle coding and also some further engine prefix codes.

Great Info - Thanks Doug

The first page below is from the hardcopy Moke parts catalogue PUB 1029R (printed on the cover) or 1029A (printed inside on first page) dated August 1977 by Leyland Motor Corporation of Australia. Seems no-one checked for consistency of the suffix before it went to print.

The next two pages are from the last of the Australian Moke parts microfiche PUB 27/1 dated June 1984. By this time the manufacturing company was JRA (Jaguar Rover Australia).

A batch of 1016 engines were fitted to mokes in 1975. The engine numbers were between 1016-3566 and 1016-4095. This website lists them http://remlr.com/

I have found another one 1016-2029 Built 7-74 so it looks like the 1016 was not exclusive to that one batch of Army mokes.

None of this really helps other than the 1016 engine was fitted in 1974 and 1975.

Thank you both, those are some fantastic resources

Seems to have filled most of the gaps now I think. The Army list was what I was going off for the 1016 Mokes too.

Has anyone ever seen a Moke of type YJBAB3R? I've only find trace of it in literature, no actual cars.

Thanks,
Evan

The only thing I’d say is that, as pointed out earlier, the 1206 to 1209 engines are not a 1200 engine with different bearing caps but a completely different block and crank. 1200 series are open chest block and the same as a Cooper S with the cross drilled AEG480 crank. The 1206 to 1209 engines are closed chest (1100S) blocks with a larger non cross drilled (1.75”) big end bearing cranks part number 12G1683 (Pretty sure that’s the number).

Cheers
Rod

Thanks for the clarification Rod, I've changed the wording in the original post so it reflects that a bit better.

No problems - I’ve got both a 1200 series and 1206 series GT so have been through the whole process of working out the differences
