Hoping i might be able to find out year of build for this M100 Grader i recently purchased
It has M100A166  as a s/n  and engine is an AC 1000 s/n 10- 11512.   American Bosch injector pump on it.  It is in not bad condition and has most recently been on a farm in central NSW for past 30 year or so.  The owners son says it originally was on the south coast of NSW.   Front windscreen is missing but all seems to work ok and most uni joints are in good nick.  Tyres will need replacing.  Uses a bit of oil in engine and engine blows a bit of blue smoke.  Thanks for your assistance and any info very much appreciated.

I dont have a specific year, but the M100A came out about 1964-65.... the 100B was in the early 1970s .... I would think sn 166 was the first or second year of manuf.
Like them all, but love the "B"s.

Allis had a plant in Oz- around Newcastle IIRC.

We have an AC Forty Five (about 1959) and the model and serial numbers don't match with the US parts manual.

I don't know if that was the case with M100's

As far as I know from reading up on A-C's history, T.C. Pollard Pty Ltd. had a factory at Carrington on the outskirts of Newcastle in NSW, and was bought over by Allis-Chalmers in 1957.  Pollard made motor graders and also scrub cutters, likely some other land machinery as well.  History about the firm seems to be quite thin, so it's not clear when the firm was founded or when A-C closed the plant.  

Looking at Norm Swinford's A-C Construction Machinery book, the M100 was in production from 1962–64, replaced by the M100 Series B 1965–73.  The engine is an A-C 10000 series diesel, (non-turbo) 6-cyl and 516 cu.inch, rated at 127bhp @ 1800rpm.  If it's still fitted with the original rims, the tyres are 9.00x24 fronts and 13.00x24 rears. For what it's worth Swinford's book mentions that the M65 grader was built in Australia, but doesn't mention whether the M100 was built at Carrington (that's not to say it wasn't, though).  Hope this helps.

Going on our Forty Five and its parts book I'd be suprised if an M 100  wasn't all 14X24 tyres from factory
