I heard from my mechanic today, who had a preliminary diagnosis of why my gearbox had ceased to function. I'm sure he won't mind me sharing his informed opinion and XXX rated snapshots for your delectation. His initial impressions:
"Nothing visible without digging into the box. I’m nosey, so I did. Oil pump probably never worked, is my guess, and it has survived on splash fed oil until it said "No more". Oil pump gears broken up, gear drive looks to have punched through the gear it drives. The square drive has rounded corners now. It has all kept going until one of the bearings, which is bone dry, started screaming and subsequently broke up. This is why it was O.K. at first, until it got hot and bigger etc. It hasn’t done reverse gear much good either, but not so important."
Ooof!
I haven't got the faintest idea what I'm looking at, but I'm sure it isn't supposed to look like that.
