Gearboxes

[les]

Some years ago, maybe ten or so, I rebuilt two gearboxes, they have been stored ever since. I’m sure one has Midget internals, the shaft has 22G 299, which I think suggests this. The other is stamped 22G 172. Probably a standard 1098. I would like conformation of these boxes please. So much water passed under the bridge since rebuilding !

Both shafts feature in the spread sheet attached.

Different ratios? Easy to spot the difference, even if you can’t work out the actual ratios.

Thanks Phil for posting that chart. One more query please. Am I right in saying each input shaft is obliged to use the parts listed under its column ? As I’m presuming the input shaft dictates what laygear is used consequently the appropriate gears ?

You are correct in that the first motion shaft will dictate the lay-gear used.
