Multiquip 20540 HD Gearbox 2" Handle Case

The Multiquip 20540 HD Gearbox 2" Handle Case is a genuine OEM component designed for HDA-Series walk-behind power trowels. Sourced directly from Multiquip, this part meets the exact specifications of the original, ensuring a correct fit within the handle assembly. The 20540 is the factory-designated replacement for HDA-Series machines, so you can order with confidence knowing it matches your equipment.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original dimensional and material standards, ensuring the case housing seats and seals correctly around the HD gearbox assembly.
• Direct Handle Assembly Fit — Designed specifically for the 2" handle configuration on HDA-Series trowels, allowing the gearbox to mount without modification or re-engineering.
• HDA-Series Compatibility — Confirmed fitment for Whiteman HDA-Series walk-behind power trowels; verify your model before ordering.
• Structural Integrity for Gearbox Protection — The case housing shields internal gearbox components from debris, impact, and contamination — a cracked or damaged case accelerates gear and bearing wear.
• Correct OEM Part Number — Ordering by Multiquip part number 20540 eliminates ambiguity and ensures you receive the exact replacement the machine was built with.

The HD gearbox handle case encloses and protects the gearbox mechanism housed within the trowel's handle assembly. It provides the structural enclosure that keeps gears properly aligned and shields them from dust, concrete slurry, and mechanical impact during operation. When the case becomes cracked, broken, or otherwise compromised, internal gearbox components are exposed to contamination and physical damage, leading to accelerated wear and potential handle assembly failure.
