Well, Now that I'm home from work, I've dug into the books with a closer eye, and it does seem rather interesting...

From what I can tell, that CSIRO Disk must be numbered CA09636A, that part number only appears on the listing for the first Vortex, it's on nothing else in the book, and the blade set with it has the same story (CA09371A)

Sure enough, as above the next two Vortex Listings have the CA09377A Disk, which I would assume is the plastic surround fan-disk, as whilst it's use was limited to the 85-86 Vortex, the 86-87 Vortex and Mustang, the 86-87 Craftsman Dlx, and finally the 87-88 Mustang GTS, the matching blade set (CA09306S) Shows up all over the place on a disk labled CA09320K, so here's guessing thats what you need to scratch over the part number if you rip off the plastic surround!

Now, here is where it gets... Interesting?..Vortex was released in 83 with the ST12636A Starter Assembly, there is a mustang the AA050A3 which also run from 1983-84, with the same Starter assembly, which was also fitted to the Sabre, Commando, Corsair, Craftsman (Std & Dlx) Silver Streak and Tiger of the same model year...

Then the following Vortex, Mustang, etc, all have the ST12651A Starter... but the 84 Sports, Corsair and Craftman's have the one from 83...Even the 85-86 Wildcat retains it, while the others by then have all shifted...

Now, I do recall the oldest power-torque starters being slightly different to newer ones, and maybe that's what I'm seeing here, But from 87 it all shifts again to the ST12645A, and I don't recall seeing 3 variations on the power-torque starter that far back... Also, the earlier starter was, at least to my knowledge, the biggest, the size dropping later on to cut cost... so why it would be continued on the lower end mowers seems hard to work out... and these numbers would suggest a total of 9 power-torque mowers released all at once in 1983...which seems odd to my understanding...

This comes from the official Victacode Spare Parts QR Guide for 1970-91... Maybe I need to pull out the Microfiche...


Cheers
Ty
