How to repair a Kenwood Chef A902 gearbox

This page just shows the differences between the models.

The main differences seem to be the lack of a dog gear, it being replaced by a direct drive gear, and that some of the gears have angled instead of straight teeth (which obviously means that these parts are not interchangeable).

This shows the gears replaced in a dry run before re-greasing and assembly.
This shows the main gearbox component parts, possibly missing the thrust washer on the rightmost gear. The missing thrust washer sits under the rightmost cog. There's some debate about the existence of this washer so don't panic if you can't find it in your Chef.
This shows the gearbox with the old grease still in situ.
