The Thwaites range of dumpers were fitted with Newage 40M gearboxes in the Thwaites 2 Tonne straight tip and Thwaites 2 Tonne swivel skip and the Newage 85M gearboxes in the Thwaites 3 Tonne straight tip and Thwaites 3 Tonne swivel skip until Newage went into administration and then both ranges were fitted with the Spicer 401. Both the Newage and the Spicer boxes fitted to the Thwaites range of dumpers were very similar in design and could be described as ‘crash type’ boxes with no syncromesh on any gears and a simple 3 forward and 1 reverse nature.
