Gear / Shaft wear

[morelli]

Hi Guys & girls,
I’d welcome any thoughts on the state of this 4th gear from a PX200. To me it looks shot due to the wear around the edges where cruciform engages but I’ve another one which has identical marks so now I’m wondering is this normal?
Also, is it normal to have wear / ridges on the insides of the gear shaft as pictured?
Thanks as always 😊

The 4th gear looks worn but serviceable to me but the layshaft should not have ridges in. The cruciform should be able to slide up and down the shaft with no resistance. Very worn I would say. The cruciform is the sacrificial element of the gearbox and you should expect wear on that.
