Description
Overview
The Argo Standard Prop Release Spring holds preload on the propeller release mechanism in an Argo V-Drive system. It ensures crisp engagement during normal running and gives a controlled slip during sudden overload. This spring matches Part Number AM1056.
Features
• It delivers consistent preload force while engaging the prop drive.
• It allows safe disengagement under extreme torque reversals.
• It uses marine-grade spring steel suited for cyclic loads.
• It fits as a drop-in replacement in correct release assemblies.
Specifications and Materials
| Part Number | AM1056 |
| Function | Prop release preload spring |
| Estimated Material | High-tensile spring steel, likely corrosion resistant |
| Estimated Weight | ~0.02 kg (approximate based on small compression springs) |
In marine environments, corrosion resistance is critical, so manufacturers often favour stainless or coated spring steel to resist salt water attack, as explained by Airedale Springs in their “Springs in the Marine Sector” guide here.
Compatibility and Fitment
You must first check that your release housing can accept a spring of the same length, coil diameter and preload. Remove your old spring and match coil count, free length and end type before purchase. Using AM1056 in a mismatched assembly may cause slip or damage.
Compliance and Safety
Apply cyclic load only within the spring’s fatigue design limits. After installation, test propeller engagement under torque and verify there is no binding. Replace the spring at the first sign of coil set, fatigue cracking or corrosion.
Marine Applications
This spring is used in ski boats, performance inboards and V-Drive installations where prop release units protect the drive train. Replacing a weakened spring often restores crisp drive behaviour and avoids nuisance slip during acceleration.
