The Multiquip 07028-057 is a genuine OEM Cotter Pin 5/32 x 1/2 designed for Whiteman plaster and mortar mixer models WM45HE, WM45HCE, and WM45H, as well as the G55H concrete vibrator. As a direct Multiquip OEM component, this cotter pin is manufactured to the exact dimensions and material grade required for correct installation. It offers a direct, drop-in replacement that restores proper fastener security to the assembly. Sourcing the correct OEM part ensures the pin seats and spreads exactly as intended, maintaining the integrity of the fastened joint.
Key Features
- Exact OEM Dimensions — Manufactured to the precise 5/32 x 1/2 specification, ensuring the pin fits correctly through the clevis or shaft bore without rework.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, this cotter pin meets the original material and hardness requirements for secure retention under vibration and load.
- Confirmed Fitment — Compatible with WM45HE, WM45HCE, and WM45H Whiteman mortar mixers, and the G55H concrete vibrator, all verified by Multiquip part number 07028-057.
- Vibration-Resistant Retention — A correctly installed cotter pin locks fasteners in place during operation, preventing loosening or disengagement on equipment subject to continuous vibration cycles.
- Safety-Critical Fastener — Cotter pins secure load-bearing and moving components; using the correct OEM-specified pin size prevents premature shear or improper spreading that can lead to fastener failure.
A cotter pin is a small but essential fastening component used to lock a bolt, clevis pin, or shaft in position, preventing it from backing out or rotating during machine operation. On mortar mixers and concrete vibrators, components such as drum pivot points, drive linkages, and handle attachments rely on cotter pins to stay securely assembled through constant vibration and mechanical stress. When a cotter pin shears, deforms, or goes missing, the fastener it secures can shift or separate, leading to loss of control of the assembly and potential damage to surrounding components.
