Multiquip 820985 Turbo Charger Stud HHN34

The Multiquip 820985 Turbo Charger Stud HHN34 is a genuine OEM component designed for the HHN-34 heavy-duty mechanical ride-on trowel. Sourced directly from Multiquip, this stud delivers an exact OEM fit, ensuring the turbocharger assembly seats and seals correctly without rework or modification. Verified against the HHN-34 parts catalog, the part is a direct drop-in replacement for worn or damaged hardware on this machine. Keep a spare on hand to get your trowel back in service without delay.

Key Features

• Genuine OEM Hardware Grade — Manufactured to the exact thread pitch, length, and tensile specification required to secure the turbocharger assembly on the HHN-34.
• Direct OEM Replacement — Installs into the existing turbocharger mounting position with no drilling, re-tapping, or fitment adjustments needed.
• Confirmed HHN-34 Fitment — Engineered specifically for the Multiquip HHN-34 heavy-duty 8-foot mechanical ride-on trowel platform.
• Turbocharger Integrity — A correctly torqued stud maintains the clamping load that keeps the turbocharger sealed under heat cycling; a stripped or broken stud can cause exhaust leaks and boost loss that take the machine out of service.
• Exhaust System Safety — Proper stud integrity prevents hot exhaust gases from escaping at the turbocharger flange joint, protecting the operator and surrounding components from heat exposure.

A turbocharger stud is a hardened threaded fastener that clamps the turbocharger housing to its mounting flange on the engine. It carries the combined load of exhaust heat, vibration, and boost pressure that the turbocharger generates during operation. When a stud stretches, corrodes, or breaks, the turbocharger can work loose from the manifold, resulting in exhaust leaks, a loss of boost pressure, and potential damage to surrounding engine components. Replacing a failed stud promptly with the correct OEM part restores the clamping force the joint needs and keeps the engine performing as designed.
