Multiquip EM303 Friction Clutch Belt Guard

The Multiquip EM303 is a genuine OEM Friction Clutch Belt Guard designed for a wide range of Whiteman ride-on and walk-behind power trowels, hydraulic ride-on trowels, rammers, and select ancillary equipment. As a direct OEM replacement, the EM303 is manufactured to the same specifications as the original part, ensuring correct fit and function across compatible models including HHXDF4-DF5, HHXD5, HHN34TVD, HHNG5, MD80, MD105, J3036H55, BS90C, BH11C, BH90C, JS60C, JH90C, JH55C, MT85, MT60H2, MTR40HF, and MT-E55. Sourcing a genuine OEM part means you get the exact guard profile and mounting configuration the machine was built around — no guesswork on fitment. When it comes to protecting drive components, the right guard matters, and the EM303 delivers the coverage your machine depends on.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the guard profile, mounting points, and material thickness match the original exactly.
• Broad Model Compatibility — Fits Whiteman ride-on trowels (HHXDF4-DF5, HHXD5, HHN34TVD, HHNG5), hydraulic ride-on trowels (MD80, MD105), walk-behind trowels (J3036H55, BS90C, BH11C, BH90C, JS60C, JH90C, JH55C), and rammers (MT85, MT60H2, MTR40HF, MT-E55).
• Direct Bolt-On Replacement — Designed to install in the original mounting location without modification to brackets or hardware, getting your equipment back in service faster.
• Drive Component Protection — Shields the friction clutch belt from debris, impact, and contact during operation, preserving belt life and clutch engagement integrity.
• Operator Safety Coverage — Properly enclosing rotating belt and clutch components is a critical safety requirement on power trowels and compaction equipment — the EM303 restores that protective barrier when the original guard is damaged or missing.
• Verified Part Number — Order with confidence using Multiquip part number EM303, cross-referenced to the correct guard for all listed models.

The friction clutch belt guard on power trowels and rammers serves a dual purpose: it physically shields the rotating belt and clutch assembly from dirt, debris, and accidental contact, and it helps direct airflow and contain components in the event of a belt failure. Without a properly fitted guard, exposed rotating parts present a safety hazard and become vulnerable to damage from jobsite debris. A cracked, missing, or improperly fitted guard should be replaced promptly to restore both operator protection and the mechanical integrity of the drive system.
