The Multiquip EM507251 Bull Gear Spacer is a genuine OEM component designed for Essick plaster and mortar mixer models EM-900S, EM-900P, EM-700S, and EM-700P. As a factory-sourced part, EM507251 meets the original dimensional and material specifications required to maintain correct gear alignment within the mixer drivetrain. Sourcing the genuine OEM version ensures the spacer seats and registers exactly as the mixer was engineered to accept it, preserving proper load distribution across the bull gear assembly. DHS Equipment stocks this part to keep your Essick mixer running at full capacity.
Key Features
- OEM Dimensional Accuracy — Manufactured to the exact thickness and bore tolerances required for proper bull gear positioning in the mixer drivetrain, preventing gear misalignment under load.
- Drop-In Installation — Engineered to register directly onto the existing shaft and gear stack without reworking or shimming, matching the original assembly configuration.
- Broad Essick Mixer Compatibility — Confirmed fitment for EM-900S, EM-900P, EM-700S, and EM-700P plaster and mortar mixer models.
- Drivetrain Stability — Maintains correct axial spacing between the bull gear and adjacent components, keeping torque transfer consistent and reducing wear on surrounding gear teeth.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, carrying the same part number (EM507251) used in factory assembly and authorized service documentation.
The bull gear spacer is a precision positioning component located within the mixer's gear reduction drivetrain. Its role is to maintain the correct axial distance between the bull gear and neighboring shaft components, ensuring the gear mesh stays properly aligned as the mixer transmits torque from the engine to the drum. When this spacer wears down, becomes deformed, or goes missing, the bull gear can shift out of position — leading to uneven gear contact, accelerated tooth wear, increased noise, and ultimately drivetrain failure. Replacing a damaged or worn spacer promptly protects the more costly surrounding gear components and keeps the mixer operating as intended.
