Key Features
- Genuine OEM Spring Tension: — Manufactured to the original spring rate and coil geometry, so the locking pin engages and releases with the correct resistance every time.
- Drop-In Installation: — Designed to seat directly into the existing locking pin assembly without reworking the surrounding hardware.
- Broad Mixer Compatibility: — Fits a wide range of Essick and Whiteman plaster and mortar mixer models, including EM70, EM90, WM63, WM70, and WM90 series machines.
- Maintains Positive Drum Lock: — A worn or broken locking pin spring allows the drum position to shift unexpectedly during operation; a fresh spring restores the firm, positive lock the operator relies on.
- Built for Commercial Mix Cycles: — Rated for the repeated engage-and-release cycles typical of continuous-use mortar and plaster mixing on an active jobsite.
The locking pin spring provides the return tension that holds the drum locking pin firmly in its engaged position during mixing and releases it cleanly when the operator adjusts drum angle or empties a batch. Without adequate spring tension, the pin can back out under vibration, causing the drum to shift position mid-cycle or making it difficult to lock securely after repositioning. Replacing a fatigued or broken spring restores the crisp, positive locking action that keeps the mixer operating safely and predictably through every batch.
