I have two w/s manuals AKD 4138 9th and 12th editions. I have noticed several errors such as the diagrams of the Mk11 and Mk111 cars having the correct front but Mk1 rears. Not confidence inspiring, I wonder what else is wrong!
The valve lifts quoted for the 3 camshafts differ quite significantly between the manuals and the info for the 1800S is missing altogether.
After possibly unravelling the typos relating to engine numbers and camshafts I wonder if anyone is able to match the engine numbers to the production year please.
18AMW UH up to 18AMW UH 27522
18AMW UH 27523 to 18AMW UH 97273
18AMW UH 97274 to 18AMW UH 101630
18AMW UH 101631 up
These are all Mk1 cars (possibly early Mk11 or Mk1.5). The engine numbers changed to 18H at the end of the 18AMW run.
Thanks for you help
David

David,
There will be a lot of people more expert on this than me but one piece of info I have gleaned from another manual is that engine 27523 marks the change from 4.187 final drive to 3.882 as standard fit and as far as I am aware this change dates to January 1965.

Nick Thanks, that's the first part of the jigsaw puzzle sorted it fits in with some other data. I just wish the w/s data on engine nos was correct or unambiguous. Good to read your gear selection is sorted.

thanks! Maybe someone here still has an original Mk1 engine in their car with engine nos that can be identified or lying around and they know the date it was made? Enjoy the LOCI National Rally later today and great photos of the driveshaft repair and info. Regards David 12th Edition too...... Chris. |

Hi, Dave!
I've got an engine from a 68 mk 1 among my spares. The number starts with 18 AMW. I'll check it out.
I've also got a BMIHT certificate for this car, with its build date etc.
I'll need some time to find it, though..
Best regards, Tommy

Picked up a 2nd edition today - might have different info in it...... Where am I supposed to be looking?

Tommy
Thanks that would be very helpful when you have time Chris
You can find the info under General Data at the front of the manual following the Tuning Data. If the 2nd edition follows the same format as the 9th and 12th it would be in subscript as a foot note at the end of the section on valves and lubrication just before ignition. (General Data p3). There are 3 footnotes, in my editions the engine numbers either appear to be confused or maybe there was overlap in production (not valve overlap  regards David

2 pics from manual. If you can't read therm, I'll ask MrsP to scan them in.   You may want to know that the original engine was included when I bought the car, although it was not salvageable. Number was 18WB-SB.AH3144. Car first registered 11.8.1967. Chris. |

Thanks Chris. With a bit of help from my manuals I have been able to decipher the engine numbers from your pics and they are consistent with my 12th edition 1972.
Although your photo cuts off most of the valve lift data it looks as though it differs yet again from my manuals! Also the valve timing rocker clearance under column 1 is shown as 21 in the one manual and 20 in the other. When Tommy was measuring his cam I kept thinking 21 not 20 so now I know I had read it somewhere!
Any idea what if any are the differences between the 18AMW engines and the 18WB/SB A/H. I have a BMC code list but it doesn't answer everything. I assume W = Wolseley and B appears to be listed as "industrial", A=Austin, H = high compression; no idea of the SB.
It looks as though your original engine may have had the hotter cam like my Mk1 from 1967.
Another piece of the jigsaw and more questions!
regards
David

I've got the 7th edition from 1969 and have been looking at some stuff written up about MGs. Here's another view on Chris' original engine.
18WB refers to Wolseley type B engine (similar to 18GB on an MGB refers to five bearing engine up to 1967)
SB - don't know yet
A - automatic transmission
H - High compression
My manual refers to 18WB in the same reference as engine 101631. Am I correct in thinking that the 18/85 was the only version available with auto trans prior to the Mk2? This could give the W instead of AMW (Austin Morris Wolseley) code.
or maybe I am making too many leaps. I know engines get swapped around.

Re my last comment. Chris, just checked a pic of your car and it's a manual.

True, but the PO fitted a MkIII Austin engine and manual gearbox - the cable brackets were still in place in the engine bay and there was a cunningly artificed (but horrible) bit of veneer covering the slot where the selector used to be. The interlock cabling had been spliced together with insulating tape....
Anyway, that's all been dealt with and I sleep better at night now.
Chris.

David - the engine number is from the V5 document. I have no record of what was on the engine itself - you know what DVLA can be like.
Chris.

Thanks Nick. Of course I should have remembered Chris' car started life as an automatic. His recent posting with photos of the driveshaft repair should have reminded me as that was the type fitted only to the autos I believe (am I right Chris?). I think maybe you are correct that the auto was an option at first only for the Wolseley 18/85 which had power steering as standard when it was launched. As far as I know the 5 bearing crank was the only one fitted to the 1800 and was one of the original sales features, but this could answer the code WB... A/H. Maybe the SB stands for power steering +  . Regards David I've got the 7th edition from 1969 and have been looking at some stuff written up about MGs.
