When you need a dependable crankshaft solution to get your roller back to full operation, this is the correct OEM part for the job.
Key Features
- OEM-Matched Crankshaft Tolerancing — Manufactured to the precise dimensional and material specifications of the original component, ensuring correct bearing clearances, stroke geometry, and journal finish for T-series roller engines.
- Direct-Fit Assembly — Supplied as a complete crankshaft assembly that installs into the engine block using the original mounting points and hardware — no modifications or custom machining needed.
- Verified Fitment for T-Series Ride-On Rollers — Confirmed compatible with Multiquip T23, T26, and T33 ride-on roller models.
- Restored Engine Power and Compression — A properly fitted crankshaft maintains correct piston travel and combustion timing, restoring full engine output and smooth operation to your roller.
- Prevents Secondary Engine Damage — Running a worn or damaged crankshaft accelerates wear on bearings, pistons, and connecting rods; replacing with this genuine OEM assembly stops further drivetrain damage.
The crankshaft assembly is the central rotating component of the engine, converting the up-and-down motion of the pistons into the rotational force that drives the machine. It works in close coordination with the connecting rods, bearings, and flywheel to deliver smooth, consistent power output. When a crankshaft becomes worn, bent, or damaged, the engine loses compression and balance, leading to vibration, reduced performance, and ultimately engine failure if left unaddressed.
