The SureStart S20 Spring Starter is our smallest and lightest starter weighing a modest 12 kg (26.5 lb). The S20 Spring Starter is suitable for diesel engines from 0.5 to 2.5 litres (30.5 to 152.5 cubic inches) and is available as a clockwise and anti-clockwise model. S50, S60 and S70 spring starters are available for larger engines.
The S20 Spring Starter brings non-electric backup starter to smaller engines, bringing with it all the reliability benefits of mechanical starters. The S20 is used for life boat engines, portable fuel pumps and water pumps in remote locations. Applications include Deutz, Farymann, Hatz, Lister, Lombardini, Kubota, Perkins and Ruggerini engines.
Although niche, there is a clear demand for anti-clockwise rotation starters. The need was especially strong where the engine did not have a second pocket for a backup starter or where there was insufficient space on the engine to mount a second starter. Once engine companies developed flywheel housings with an extra pocket for a backup starter (especially common for with lifeboat engines) the opportunity was there to develop anti-clockwise mechanical starters.
Anti-clockwise SureStart spring starters are simple to install and cost-effective. They deliver a dependable starting system that does not require external energy such as electric, hydraulic or pneumatic power.
