Choosing the Right Spring Starter Series for Your Engine's Displacement
Selecting a mechanical spring starter isn't a one-size-fits-all decision — the right unit depends entirely on the displacement and power requirements of the engine it needs to crank. Cqstart addresses this with a full lineup spanning nine series, each matched to a specific displacement range and built with the corresponding weight and torque capacity to handle it reliably.
At the smaller end, the 7 Series covers engines under 2L at just 11kg, ideal for compact equipment where weight and space are limited. Moving up, the 5 Series (1–4L, 16kg) and 1 Series (4–7.5L, 18kg) serve mid-range diesel applications. For heavier-duty needs, the 2 Series (7.5–11L), 4 Series (10–13L), 3 Series (13–16L), and 6 Series (16–30L) scale up in both capacity and weight accordingly, topping out with the 0 Group System, rated for engines up to 50L and weighing 50–55kg.
The W Series stands apart as a flexible option covering a wide 1–30L range, useful where application demands vary. Matching displacement to the correct series ensures reliable starts without over- or under-sizing the equipment.
