The Multiquip 28441ZH8003 is a genuine OEM Friction Spring designed for a broad range of Multiquip, Whiteman, Essick, and STOW equipment. This is a direct OEM replacement sourced from Multiquip, ensuring correct specification and compatibility across plate compactors, concrete and mortar mixers, masonry saws, pumps, walk-behind trowels, generators, and more. Compatible models include MVC-64H, MVC-70HW, MVH-120GH, MVH-150GH, WM70, MC-42S, MC-64S, EC-42S, QP-202TH, MS18H5.5, CA4HM, and many additional machines across the Multiquip portfolio. Because this spring is shared across such a wide equipment range, always confirm your model code before ordering.
Key Features
- Genuine OEM Spring Tension: — Manufactured to the exact load rating and free-length specification required across the Multiquip equipment range, so the spring delivers consistent friction control from day one.
- Drop-In Replacement: — Matches the original mounting points and hook geometry, allowing straightforward installation without machining or modification to adjacent components.
- Broad Cross-Equipment Compatibility: — A single verified part number covering plate compactors (MVC, MVH series), mortar and concrete mixers (WM70, MC, EC, CMS, WC series), masonry saws (MS, MP series), diaphragm and trash pumps (MQ-D, QP series), walk-behind trowels (CA, JA, J series), and portable generators.
- Maintains Consistent Friction Control: — A correctly tensioned friction spring keeps throttle, governor, or engagement mechanisms operating smoothly; a fatigued or broken spring leads to erratic speed control, slipping engagement, or loss of governor response.
- OEM Part Number Assurance: — Supplied under Multiquip part number 28441ZH8003, so you can match it directly against your parts manual or service bulletin without guesswork.
A friction spring is a small but critical tensioning component used throughout construction equipment to maintain controlled resistance in governor linkages, throttle assemblies, clutch engagement mechanisms, and similar moving systems. It works by applying a calibrated spring load that keeps linked components in steady contact or returns them to a neutral position after actuation. When a friction spring loses tension through metal fatigue, corrosion, or physical damage, the result is typically inconsistent engine speed, slipping or dragging engagement, or a governor linkage that hunts and surges rather than holding a steady setting. Replacing a worn friction spring with the correct OEM part restores the designed operating response and protects the surrounding linkage components from accelerated wear.
