SureStart S30

The SureStart S30 Spring Starter is suitable for diesel engines from 1.1 to 6.6 litres (67.1 to 402.7 cubic inches) and is available as a clockwise and anti-clockwise rotation model. S20 spring starters are available for smaller engines. S50, S60 and S70 spring starters are available for larger engines or engines requiring a cold-start capability.

The SureStart S30 Spring Starter has a two piece mounting bracket which means this starter is easy to convert to another model just by replacing part of the mounting bracket (mounting flange). This makes the S30 an efficient and economical unit.

The use of radial securing screws ensures the starter is more compact and installation onto an engine is easier in comparison to other mechanical starters of a similar type in the market.

The SureStart S30 Spring Starter is a popular starter and used in many applications including Caterpillar, Cummins, Detroit, Man, Perkins, Scania and Volvo.

Anti-Clockwise SureStart S30 Spring Starter

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 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.
