40-5 Recoil Starter Spring: The "Startup Reset Power Source" of Low-Power Models

The 40-5 Recoil Starter Spring is the "startup reset power source" for 40-5 low-power model recoil starters—it is cold-rolled from high-carbon spring steel, with a stable elastic torque of 1.2N·m, which can store potential energy evenly when the pull rope is pulled, and smoothly drive the rope to reset after release, avoiding jamming or incomplete reset.

Its surface is blackened for rust prevention, which can withstand moisture and oil erosion in the engine compartment for a long time, with an elastic attenuation rate of less than 3% (after 1500 uses); the number of turns of the spiral structure is precisely matched with the recoil starter reel, with no loosening or interference after installation, adapting to high-frequency startup scenarios.

In 40-5 recoil starter use, old springs are prone to rope reset difficulties (pull rope jamming, unable to restart repeatedly) due to elastic attenuation and deformation. After replacing this spring, the reset smoothness of the recoil starter is fully restored, and the rope reset success rate after a single startup reaches 100%.

Whether for small home generators or outdoor portable tools, the 40-5 Recoil Starter Spring can provide stable reset power for the recoil starter with "high elasticity + corrosion resistance" performance, being the core elastic component for "repeated smooth startup" of low-power equipment.
