Rootes Commer TS3 engine

At this point, i will relate (again) a memory from my brother (Ronald) while driving our Commer (TS3) tipper, on a particularly heavy site, and very slowly making his way toward tipping. He was just about making progress (forwards) and in second gear, when further progress required dropping to first. By the time first gear was selected, the engine took over the direction of the gearbox and began propelling the lorry backwards! The engine reversed itself! True.

Not that uncommon with two strokes, although four stroke engines could do the same. The Saurer diesels used by Morris-Commercial were notorious for that (and occasionally igniting the cab!) and I had the same thing setting off in crawler on a steep hill with the Gardner 6LXC in my Sed Ak 400, as did several of our other drivers.

Father had a 3.4 BMC in the first of the FE Austins that did it, didn’t do the engine a lot of good, it wasn’t the same afterwards and a new one was fitted under warranty.
