1098 Crankshaft

[bwaminispeed]

Did the 1098 Clubmans have a tag (GT etc) to differentiate them from the standard 998, and, 1275 GT????

I just remembered where that crossdrilled ENT16 crank came from, it was out of a Clubman wagon that was imported to Canada from South America in a very rusty state as a parts car for a build with a brand new Clubman shell......I believe it was on a rod shift box.....but, no clue what year it might have been....

Hi Guys

In South Africa we have the clubman 1098 engine that has the crank part number 12G2827. This is a pre A+ engine that is a big bore engine. The engine number will also be 10H and the oil filter will be top left of the engine block a Z93. No tappet chest covers or the like. Also ran rod type gearboxes.

Sorry, I didn't mean to distract with my post re: 1100 A+ Engines, but it's fairly clear, while a little obscure, certainly were made - thanks Luis and Al for confirming - as were 850 engines (in an A Block ) up to about 85 - 86 and fitted to the Metro.

I have posted this up here before, this may help to some degree in finding an 1100 crank. It appears there was at least 4 different 1100 Transverse Cranks made, some were cross drilled (bwaminispeed posted one up here a couple of months back), this chart shows regrind and re-treatment limits as suggested by the Factory



The other 1100 crank that's not on that list is the 12G82, which I think was the thin tail type.

And, here it is again.......

Those are 1275 cranks though........including those used in the 1275 powered 1100 range before the 1300 arrived in 1967.

Crank shaft forging number is 12G82.......which, is, none of the above.......

12G82 is a std 1100 crank. We have hundreds of them, mostly all cracked, but 100s all the same.

Still no evidence of a 1100A+ engine being produced...

[bwaminispeed]

Are they all cross drilled???

[Spider]

There wasn't an A+ 1098 either.

For a brief (and perhaps, obscure) period there was an A+ 1100, in 79 and 80.

I doubt that. I used to service a 1981 Allegro 1100 on an W plate that was most definitely an A Series. These were replaced early '81 by a 998 A+

The A+ was completely different. Everything was changed. BL would not have spent money making an engine they were not fitting to any production cars.
The first car to use an A+ engine was the Morris Ital in mid 1980. The A+ block was however trialled in a handful of cars in 1979-80 including some 998's and therefore very possibly 1100's. They are not A+ engines however.

The Gold Seal replacements 1100 A+ had a Part Nos BKM 1229 and RKM 1151

The A+ went in to production either late 78 or early 79. We started getting them in our 1979 Mokes and there was roughly a 6 month lag between UK production and what we got here at that time.

Those are 1275 cranks though........including those used in the 1275 powered 1100 range before the 1300 arrived in 1967.

Despite the title on the page, they are not all 1275 cranks.

I've worked on three 1979 Mini Specials over here and all have 1098cc A+ engines with 22G1832 pre-A+ gearboxes, clutch assembly and tranfer gears. All three are factory original cars

Those have A+ blocks. These were trialled by BL before the Metro launch.

[Costafortune]

There probably wasn't one, just the few built with A+ blocks to test them long term. I've seen and had enough late Clubmans to know they didn't have one.

But there is no doubt that some Minis had an A+ 998 and 1275 from mid 1980 and before the Metro launch. Given the relatively tiny extra cost of producing a 1098 crank and four pistons, it's a pity BL didn't make one for the Metro HLE with an even taller final drive.

[bwaminispeed]

One more time, were all 1100 cranks cross drilled......I have 3 that are.....

[Supersonic]

No the later 12G82 crankshaft was not cross-drilled. The early 12G94 crankshaft had cross-drilled big end journals and according to the 1100 Club records and the book Anatomy of the Classic Mini, they ran from MG 1100cc engine number 10GR/TA/ 101 to 10GR/TA/5706 making 5,605 units.

Thanks for that info....

My 12G82 crank has cross drilled big ends, (as per picture), does that just mean, it's an earlier 12G82, and, what would it have been in.....

Still no one has shown tangible evidence of an 1100A+ engine.

They were never fitted to Aussie Mokes. The closest we got was a 998 with some A+ casting mods. Or a 1275 with a timing chain tensioner.

Thats because they were never produced.
Someone is being an egotistical maniac again.

850Man, I know you enjoy rubbing people up the wrong way, but there really isn't any need for stuff like this. We can disagree, but there's no need for petty insults!

Indeed.

Everyone knows the correct word is egomaniac.

I never knew there was a special crank for the early MG1100's. What an incredible pool of info this place is.

Above are the the two Mini Specials I've did work on and both are factory original. Both have A+ engines. BBT 153V has super low mileage and was bought from the Patrick Collection

And, here it is again.......

Cross-Drilled-998-Crank-02.jpg

I have a 12G82 exactly the same as yours, cross drilled with the two grooves in the centre.

I also have a 12G82 which isn't cross drilled and doesn't have the grooves. Note 'button' in casting on the right and also some more numbers cast into it.

Sorry Mark, but I tell it how it is.
If that bloke from Sydney is going to continue to talk bullshit on here, the only forum left he hasn't been banned from, then I will continue to ask for evidence of his fairytail stories.
Maybe he should stick to being an Electrician and stop trying to make everyone believe he is some kind of professional Mini specialist.
