Another thing I am struggling with is getting a fan belt. ESM don't have any but the ones they sell for the 1098 with dynamo are 825mm. On eBay they are 813mm. Other belts are 865mm or 925mm for the 1098. I know it depends on whether they have a dynamo, factory alternator or aftermarket alternator but I cannot find any consistency here.
Now I wonder if I am getting confused by the naming. Was the Minor 1000 model name used for both the 948cc and the 1098cc engined cars?
Belts do seem to vary....
On other cars of the Dynamo era, back in the day, I always found that by slackening off the tension adjustment on the dynamo mounting, I could fit a belt over all the pulleys and get sufficient tension on the belt. That just doesn't seem the case on my minor (1098 engine).
The belt that was fitted when I got him was 814, which only just fitted without using any of the adjustment to tension it.
So I then fitted a 838, which just fitted over the pulleys but was pretty near the end of the adjuster, so after a bit of use was too slack and couldn't be adjusted out further.
I'm now using the 825, which doesn't quite fit over the pulleys and needs the Dynamo mounting bolts to be removed to get it on.
I often wonder if there's an issue with the mounting brackets.
I find the reason the Dynamo doesn't quite adjust enough to allow fitting is that the insulation around the main terminal catches on the bracket, when the Dynamo is hinged towards the block...
A past Owner has removed some of the brown insulation which seems to be excessive for the terminal, I'm thinking about taking a little more off and I suspect it will be sufficient to allow belt fitment without demounting the thing...
