Wacker Neuson 5100074356 Involute Spline Shaft

The Wacker Neuson Involute Spline Shaft is a genuine OEM component designed for the RC110 ROPS, RC110 CAB, RC110p ROPS, and RC110p CAB compact track loaders. As a factory-sourced part, it is manufactured to the exact tolerances required for proper drivetrain engagement in your machine. Confirm your model number before ordering — this shaft is verified for the RC110 and RC110p series across both ROPS and cab configurations.

Key Features

• Exact Spline Geometry: — Manufactured to OEM tooth profile and pitch specifications, ensuring full engagement with mating drivetrain components and eliminating slop or uneven load transfer.
• Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, so the material grade, hardness treatment, and dimensional tolerances match the original shaft in your machine.
• Direct-Fit for RC110 and RC110p Series: — Confirmed fitment across RC110 ROPS, RC110 CAB, RC110p ROPS, and RC110p CAB configurations — drops into place without modification.
• Maintains Full Power Transfer: — A properly functioning involute spline shaft delivers clean, consistent torque from the drivetrain to the working components; a worn or damaged shaft causes vibration, slippage, and accelerated wear on connected parts.
• Built for the Demands of Compact Track Loaders: — Engineered to handle the cyclic loading and torque spikes common in loader operation, where drivetrain components face continuous stress through lifting, pushing, and directional changes.

An involute spline shaft transmits rotational torque between connected drivetrain or hydraulic components by interlocking with a matching splined hub or coupling. The involute tooth profile distributes load evenly across the full contact area, which reduces stress concentration and extends service life under heavy-duty conditions. When the spline teeth wear down or the shaft is damaged, torque transfer becomes inconsistent — leading to vibration, loss of drive power, and potential damage to surrounding components if left unaddressed.
