Multiquip 21758 Hinge Pin CA4 Handle

The Multiquip 21758 Hinge Pin CA4 Handle is a genuine OEM replacement designed for CA4HC, CA5BC, and CA4HM Whiteman walk-behind power trowels. As a direct OEM component, part 21758 is manufactured to the exact specifications required for proper handle articulation and secure fit on C and CA Series machines. This is the same part supplied through Multiquip's authorized distribution network, ensuring you receive the correct component the first time. Compatible units include the CA4HC, CA5BC, and CA4HM models.

Key Features

• Genuine OEM Construction — Machined to exact dimensional tolerances required for the CA4 handle hinge point, ensuring the pin seats fully and holds securely without play or binding.
• Drop-In Handle Replacement — Engineered to align directly with the existing hinge bore on CA4HC, CA5BC, and CA4HM trowels, allowing straightforward installation without modification to surrounding hardware.
• Broad C and CA Series Coverage — Confirmed fitment across CA4HC, CA5BC, and CA4HM Whiteman walk-behind power trowel models, covering both C and CA Series configurations.
• Restored Handle Control — A correctly functioning hinge pin keeps the handle assembly stable and properly articulated, giving the operator consistent control over blade pitch and machine direction.

The hinge pin on a walk-behind power trowel connects the handle assembly to the machine frame at its pivot point, allowing the operator to adjust handle angle and maintain steering control during finishing passes. When this pin wears, becomes loose, or fails entirely, handle movement becomes imprecise or unstable, making it difficult to control blade pitch and guide the trowel accurately across the slab. Replacing a worn hinge pin restores the solid, responsive handle feel that operators rely on for consistent, high-quality concrete finishing results.
