Multiquip EM600012 Main Transmission Housing

The Multiquip EM600012 is a genuine OEM Main Transmission Housing designed for Essick mixer models EM900SD, EM120SM, and the EM12M series. Sourced directly from Multiquip, this housing is manufactured to the exact dimensions and material specifications of the original component, ensuring a correct fit without guesswork. If your Essick mixer is showing signs of transmission wear, housing cracking, or gear alignment issues, the EM600012 is the correct factory-authorized replacement to restore your machine to full working order.

Key Features

• Genuine OEM Construction: — Cast to original structural tolerances, this housing maintains the precise internal geometry required for proper gear alignment and load transfer within the transmission assembly.
• Direct Bolt-On Replacement: — Engineered to match the original mounting points and bore dimensions of the EM900SD, EM120SM, and EM12M series, so installation follows the same procedure as the factory-original unit.
• Essick Mixer Compatibility: — Confirmed fitment for EM900SD, EM120SM, and EM12M series Essick plaster and mortar mixers sold under the Multiquip portfolio.
• Structural Integrity Under Load: — The transmission housing bears the mechanical forces generated during mixing cycles; a cracked or worn housing leads to gear misalignment, excessive vibration, and accelerated drivetrain wear across the entire transmission.
• Factory-Authorized Part Number: — Part number EM600012 is the Multiquip-designated replacement, eliminating any confusion when ordering and confirming you receive the correct housing for your specific mixer model.

The main transmission housing is the structural core of the mixer's drivetrain. It encloses and aligns the gears, shafts, and bearings that transfer power from the engine to the drum, keeping all rotating components in proper relationship with one another. When the housing is cracked, warped, or otherwise compromised, gear mesh deteriorates, bearings lose their seating, and the entire transmission becomes vulnerable to rapid failure — often taking surrounding components with it.
