G'day folks,

Yes, the smaller ~65mm one is 28 teeth, which is correct for the Masport Home Gardener, as are the double keyways.

But there are two gearbox versions for those; the Mk I was inch pattern, and the current Mk II is metric pattern.

An accurate measurement of the shaft bore would determine which system it follows, I'd say.

Cheers,
Gadge
