The Multiquip 1131 Worm Gear Case is a genuine OEM component designed for JTO-Series ride-on power trowels, AR14H rollers, J36E2 walk-behind power trowels, and international J Series and B Series walk-behind power trowels. As a factory-authorized part, the 1131 is manufactured to the exact tolerances required by Multiquip equipment, ensuring a correct fit within the drivetrain assembly without adaptation. Sourced directly through DHS Equipment, this part carries the assurance of full OEM traceability and verified part number accuracy for your records.
Key Features
- Precision-Cast OEM Housing — Manufactured to Multiquip's exact dimensional specs, maintaining correct gear mesh alignment and worm gear engagement within the drivetrain.
- Drop-In Drivetrain Replacement — Mounts directly to existing hardware on compatible Multiquip trowels and roller models, preserving original mounting geometry.
- Broad Fitment Coverage — Compatible with JTO-Series ride-on trowels, AR14H rollers, J36E2 walk-behind trowels, and J Series and B Series international walk-behind models.
- Protects Internal Gear Set — The case provides structural support and enclosure for the worm gear assembly; a cracked or worn housing allows lubricant loss and contaminant ingress, accelerating internal wear.
- Genuine OEM Part — Carries full Multiquip OEM designation, making it the correct choice for warranty-sensitive repairs and fleet maintenance documentation.
The worm gear case is the structural housing that encloses the worm gear and worm wheel assembly within the trowel or roller drivetrain. It holds the gear set in precise alignment, retains the lubricating oil that keeps the gears running smoothly, and absorbs the mechanical loads generated during operation. When the case is cracked, damaged, or worn, oil leaks out, contamination enters, and the gear mesh breaks down — leading to loss of drive efficiency, increased heat, and eventual drivetrain failure. Replacing a compromised case promptly with the correct OEM part restores the sealed, load-bearing environment the gear assembly needs to function properly.
