Spring Starters - SureStart

Mechanical starters are a reliable, cost-effective way to start diesel engines.

IPU’s range of SureStart spring starters are a reliable, cost-effective way of providing manual starting for diesel engines in a variety of applications. Available for engines up to 12 litres, they are ideally suited to harsh environments such as offshore and marine and provide an ideal low-cost alternative to electric starting systems.




Benefits of spring starting

  • Guaranteed starting. Long shutdowns, damp, cold or harsh environments don’t affect the engine cranking because of the manual operation
  • Reliability. A long and proven track record with many spring starters still operating after decades in service.
  • Space and weight saving. Starting at only 18kg and less than 50% the weight of a conventional electric starter.
  • Operator safety. The crank will not fly off or kick back during operation, and the motor can be unwound if not required.
  • Ease of use. Spring starters are a direct ‘bolt-on’ alternative to electric starters providing quick and easy installation.
  • Reduces battery costs. For certain applications, such as pumps, welders and gen-sets you can remove the need for a battery completely.
  • Lower electrical costs. Without the need for an electric starter a lighter duty alternator can be fitted or your existing alternator will last longer

How do spring starter motors work?

IPU’s mechanical starter motors come complete with a winding handle. Simply push a button on the motor to engage it and wind the handle until a coloured indicator on the motor changes. Then remove the winding handle and, to start the engine, pull on the trip lever on the motor. It’s that simple! We’ve even produced a video that shows just how simple they are to operate:
