Our old dumper truck wouldn’t stop when the stop button was pulled – a real ironic case of a Stop button causing a Stoppage!

The cable from the spring loaded pull knob had come adrift. The cable is very similar to any brake cable found on bicycles and any vehicles, which is connected to the cylinder head of the diesel engine to open a gate valve to disrupt the compression chamber’s integrity so the fuel cannot be pressurised, and cause the next explosion to drive the piston down again, thus stopping the cycle of the engine.

We will have to surf the net for a spare part, hopefully we can find someone who has a new bit, or else, we will have to make a new switch mechanism to achieve the same job!!

P.S. Found a new part, a complete knob and cable for £10, should be delivered Wednesday.
