Thwaites Orion Dumper Stuck in Gear

[Alptf]

Hi,

We have a Thwaites Orion Dumper, which has been great, however I was using it yesterday and after 3 or 4 hours it is stuck in gear? any solutions please?

Many Thanks,
Alwyn

Probably easiest to take the top off the gear box complete with the lever. At a guess the end of the gear lever has left a selector behind, as it were. The old (probably Newage) gear boxes are fairly simple. You can buy a new plate and spring and even a lever if the ball is worn ( I have welded up one with partial success). If the selectors are knackered that might be a bit more involved. You also see what sort of state the inside is, these old boxes are prone to water ingress down the gear lever.

If its the 40M2S gearbox, this is the manual.
