The Multiquip 2792351117 Piston Ring Set is a genuine OEM component designed for the B46S90 Whiteman walk-behind power trowel. Sourced directly from Multiquip, this ring set is manufactured to the exact specifications required for proper engine sealing and compression in B46S90 series machines. When it comes to internal engine components, using the correct OEM part ensures consistent performance and a proper fit within the cylinder bore. DHS Equipment stocks this part so you can get your trowel back to work without compromise.
Key Features
- Genuine OEM Compression Integrity — Manufactured to Multiquip's exact ring gap tolerances and material grades, ensuring proper cylinder sealing rather than an approximate fit.
- Direct Engine Replacement — Engineered to drop into the cylinder bore of B46S90 engines with correct ring profile and groove dimensions, simplifying the rebuild process.
- B46S90 Fitment Confirmed — Verified for Whiteman B46S90 walk-behind power trowels; always cross-reference your model code before ordering.
- Compression and Oil Control Restored — A worn or broken piston ring set causes loss of compression, increased oil consumption, and rough engine operation — this set restores full combustion efficiency.
- Long-Term Engine Protection — Proper ring seating reduces blow-by and keeps combustion gases from contaminating crankcase oil, extending the service life of surrounding engine components.
Piston rings seal the gap between the piston and the cylinder wall, performing two critical jobs: containing combustion pressure to generate power, and preventing engine oil from entering the combustion chamber. A complete piston ring set typically includes compression rings, which maintain cylinder pressure, and an oil control ring, which regulates oil film on the cylinder wall. When rings wear, score, or break, the engine loses compression, burns oil, produces excessive exhaust smoke, and delivers noticeably reduced power output — making timely replacement essential to keeping the engine running at full capacity.
