The Multiquip 21489 Flat Spacer 2.13 x 1.44 x.060 is a genuine OEM component designed for HTN27K and HTN28K mechanical ride-on power trowels. As a direct Multiquip OEM part, 21489 is manufactured to the exact material thickness and dimensional tolerances required for correct stack-up and alignment within the assembly it supports. Confirmed fitment covers the HTN27K and HTN28K models, so you can order with confidence knowing this spacer seats correctly without any modification. DHS Equipment supplies this part straight from the Multiquip OEM catalog, ensuring you receive an authentic replacement every time.
Key Features
- Exact Dimensional Spec: — Produced to a precise 2.13 x 1.44 x .060 inch profile, maintaining the correct clearance and component spacing the trowel assembly depends on.
- Genuine OEM Material Consistency: — Manufactured from the same material grade as the original, ensuring the spacer holds its thickness under the compressive loads typical in ride-on trowel drivetrains.
- Direct Drop-In Replacement: — Matches the original mounting footprint and thickness exactly, allowing straightforward installation without shimming or adjustment.
- Confirmed HTN27K and HTN28K Fitment: — Verified for use on Multiquip HTN27K and HTN28K mechanical ride-on trowels, covering both models in this light-duty 6-foot trowel series.
- Proper Alignment Preserved: — Correct spacer thickness keeps mating components properly positioned; an undersized or worn spacer can introduce unwanted play, vibration, or uneven blade pitch response.
A flat spacer is a precision shim used to set and maintain the correct positional gap between two mating components in an assembly. In a ride-on power trowel, spacers like this one are used throughout the drivetrain and blade pitch mechanisms to control alignment, axial clearance, and load distribution between moving parts. When a spacer is missing, damaged, or replaced with one of incorrect thickness, the components it separates can shift out of alignment, leading to accelerated wear on adjacent parts, inconsistent blade pitch, or unwanted vibration during finishing passes.
