Multiquip 9111 LS H Arm Return Spring

The Multiquip 9111 LS H Arm Return Spring is a genuine OEM component designed for a wide range of Multiquip rammers and ride-on and walk-behind power trowels. As a direct OEM replacement, part 9111 is built to the same specification as the original, ensuring consistent function across compatible equipment. This spring fits models including MT85, MT60H2, MD80, MD105, HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, STX6H, HTX6H, HTXG6DF, HTXD6i, STXD6i, STXDF, HDA-Series, HHN31V, HHN34TVD, HHXD5, HHXD5-ES, HHXG5, HHNG5, HHXDF4-DF5, HTN-KHOLER/ONAN/HONDA, and EHHNK5. Sourcing the correct OEM spring protects the integrity of the arm return mechanism and keeps your machine operating as intended.

Key Features

• Genuine OEM Spring Tension: — Manufactured to the original load and return-rate specification, so the H arm cycles with the same force and speed as when the machine left the factory.
• Drop-In Replacement: — Matches the original mounting points and coil geometry for a straightforward swap with no modification to surrounding hardware.
• Broad Multiquip Fitment: — Verified for MT85, MT60H2, MD80, MD105, HTX44 series, STX55 series, STX6H, HTX6H, HDA-Series, HHN series, HHXD/HHXG/HHNG series, STXDF, STXD6i, HTXD6i, HTXG6DF, and EHHNK5 equipment.
• Consistent Arm Return Action: — A correctly tensioned return spring keeps the H arm snapping back to its neutral position on every cycle, maintaining operator control and blade pitch response on trowels and proper ramming cadence on rammers.
• OEM Part Number Accuracy: — Ordering by Multiquip part number 9111 eliminates guesswork and cross-reference errors when sourcing a replacement spring for mixed fleets.

The LS H arm return spring provides the restoring force that pulls the H arm back to its neutral or home position after each actuation cycle. On ride-on and walk-behind power trowels, this action directly influences blade pitch control and steering response — a fatigued or broken spring causes sluggish or uneven arm return, leading to inconsistent blade angle and loss of finish quality. On rammer applications, the return spring contributes to the consistent up-stroke timing of the mechanism; a failed spring reduces stroke efficiency and can place additional load on surrounding components. Replacing a worn spring promptly with the correct OEM part restores predictable, repeatable performance across every work cycle.
