Multiquip 45951 90 LB Isolator

The Multiquip 45951 90 LB Isolator is a genuine OEM component designed for MD80 and MD105 mid-sized hydraulic ride-on power trowels. As a direct Multiquip OEM part, it meets the original design specifications for these machines, ensuring correct load rating and mounting compatibility. This isolator is verified to fit the MD80 and MD105 series, making part selection straightforward when servicing your trowel. Sourced from Multiquip and sold by DHS Equipment, the 45951 is the correct replacement when your original isolator shows signs of wear or deterioration.

Key Features

• OEM-Rated Vibration Control: — Engineered to the exact 90 LB load rating specified for these trowels, ensuring the isolator absorbs operational vibration without sagging or over-compressing.
• Direct Bolt-On Replacement: — Matches the original mounting configuration on MD80 and MD105 frames, dropping into place without modification to brackets or hardware.
• Confirmed Fitment for MD Series Trowels: — Verified for MD80 and MD105 hydraulic ride-on power trowels, so you can order with confidence.
• Preserves Operator Comfort and Machine Stability: — A functioning isolator dampens vibration transmitted through the trowel's frame and handle assembly, keeping the machine stable and reducing operator fatigue during extended finishing runs.
• Genuine Multiquip OEM Part: — Manufactured to Multiquip's original material and compression specifications, not a generic substitute, so performance matches what the machine was built around.

An isolator is a rubber-bonded mounting component that absorbs and dampens vibration between two connected parts of a machine — in this case, within the frame or handle assembly of the ride-on trowel. On hydraulic ride-on trowels like the MD80 and MD105, isolators prevent excessive vibration from transferring through the chassis, protecting both the operator and surrounding components from the constant oscillation generated during concrete finishing. When an isolator deteriorates — cracking, hardening, or collapsing — vibration increases noticeably, accelerating wear on fasteners and structural components and making the machine significantly harder to control.
