The Multiquip 12950811700 Cylinder Head Assembly STXD6i is a genuine OEM component designed for the STXD6i hydrostatic ride-on power trowel. Sourced directly from Multiquip, this assembly meets the exact engineering specifications required for the STXD6i platform, ensuring a correct installation with no guesswork. If your trowel is showing signs of compression loss, overheating, or engine performance issues, this is the factory-correct replacement to restore full operation.
Key Features
- Genuine OEM Cylinder Head Integrity — Manufactured to the exact material grade, port geometry, and combustion chamber tolerances specified for the STXD6i engine, ensuring proper compression and sealing from the first startup.
- Direct-Fit for STXD6i Trowels — This assembly matches the original mounting pattern and head bolt configuration of the STXD6i, allowing for a straightforward installation using standard tooling.
- STXD6i Compatibility Confirmed — Verified fitment for Multiquip STXD6i hydrostatic ride-on power trowels, so you can order with confidence.
- Restores Full Engine Output — A correctly sealed cylinder head maintains the compression ratio the engine depends on to deliver consistent blade speed and hydraulic drive performance across the trowel deck.
- Prevents Escalating Engine Damage — A cracked, warped, or blown cylinder head left unaddressed can allow coolant or combustion gases to contaminate engine oil, leading to accelerated internal wear across the entire engine assembly.
The cylinder head assembly forms the top of the engine's combustion chamber, sealing the cylinder bore and housing the intake and exhaust valves that control airflow through the engine. It works in conjunction with the head gasket to contain combustion pressure, which is what drives the piston and ultimately powers the trowel's hydraulic system and blade rotation. When the cylinder head is cracked, warped, or suffering from gasket failure, compression drops, engine temperatures climb, and the machine loses the power it needs to finish a concrete pour on time. Replacing it with the correct OEM assembly restores the combustion seal and gets the STXD6i back to full operating capacity.
