Sourced through Multiquip's authorized parts network, 809784 is the correct service part to specify when replacing worn or damaged cylinder head hardware on the HHNG5. DHS Equipment stocks genuine Multiquip OEM parts so you can get the right component the first time.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to the exact thread form, grade, and dimensional spec required for cylinder head applications on the HHNG5, where under-spec hardware can lead to fastener failure or head sealing issues.
- Direct Drop-In Replacement — Matches the original bolt pattern and seating surface on the HHNG5 cylinder head, threading in exactly as the factory-installed hardware did.
- Confirmed Fitment for HHNG5 — Verified for Whiteman HHNG5 ride-on power trowels, so you can order with confidence for that specific machine.
- Correct Clamping Force for Engine Reliability — A properly spec'd cylinder head screw maintains the compression seal between the cylinder head and block; a stripped or incorrect fastener risks compression loss and engine damage.
- Corrosion-Resistant Hardware Grade — Built to withstand the heat cycling and vibration environment of a working trowel engine, resisting loosening and corrosion over repeated service intervals.
A cylinder head screw secures the cylinder head to the engine block, creating the clamped joint that keeps the head gasket compressed and combustion gases sealed within the cylinder. When these fasteners are worn, stripped, or improperly torqued, the head gasket can lose its seal, resulting in compression leaks, overheating, and engine performance loss. Using the correct OEM-spec fastener — with the right thread pitch, length, and tensile strength — is essential to achieving proper torque values during assembly and maintaining long-term engine integrity on your ride-on trowel.
