The Multiquip 21036 Belt Guard Muffler Support is a genuine OEM component designed for HHN34TVD and HTN-31VTCSL5 mechanical ride-on trowels. This structural support bracket serves double duty — protecting the drive belt from debris and heat while anchoring the muffler in position during operation. Sourced directly from Multiquip, part 21036 delivers the exact fit and material specification your machine requires. DHS Equipment stocks this part to keep your finishing equipment running at full capacity.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original engineering specification, ensuring the correct bracket geometry, mounting hole pattern, and material grade for structural integrity under sustained engine heat and vibration.
- Direct-Fit Replacement — Bolts into position on compatible mechanical ride-on trowels without modification, aligning precisely with existing belt guard and exhaust mount points.
- Compatible with HHN34TVD and HTN-31VTCSL5 — Confirmed fitment on Multiquip's HHN34TVD heavy-duty 8-foot ride-on trowel and HTN-31VTCSL5 mechanical ride-on trowel series.
- Dual-Purpose Structural Role — A single component that both shields the drive belt from exhaust heat and secures the muffler, maintaining correct exhaust positioning and belt longevity simultaneously.
- Heat and Vibration Resistance — Positioned in a high-stress zone where engine vibration and exhaust temperatures are constant; the OEM-spec material grade is matched to withstand these specific operating conditions.
- Exhaust Safety Function — Correct muffler support prevents exhaust component movement that could direct heat toward operator or flammable materials, making prompt replacement critical when this part is damaged or missing.
The belt guard muffler support is a combined structural bracket that performs two critical functions on a mechanical ride-on trowel. It shields the main drive belt from direct exhaust heat, which left unprotected can cause premature belt degradation and unexpected failure mid-pour. At the same time, it holds the muffler securely in place, preventing vibration-induced shifting that could crack exhaust connections or redirect hot gases toward the operator or surrounding equipment. When this bracket is bent, cracked, or missing, both the drive system and exhaust integrity are compromised — making timely replacement essential to safe, productive finishing operations.
