It was deleted by the factory during TR4 production. Looks like you either
have an earlier gearbox, or someone has replaced with the wrong shaft.

While I don't think the retaining screw makes any useful difference, I do
like having the grease zerk on the end of the shaft to lube the bushing at
that point. I drilled and tapped mine to add the zerk (although I don't
know if there is room for it on a TR4A).
