35AX Crank Drive Washer Details

This OS23108000 35AX drive washer from O.S. Engine acts as a slim axial spacer for compatible drive assemblies. Positioned between the crankshaft and drive hub, it controls endplay and helps maintain correct alignment under load.

The washer ensures steady spacing at the hub interface, which reduces uneven wear and helps the driveline run more smoothly. It is typically fitted when rebuilding the crankshaft or when replacing worn thin spacers to recover intended axial clearance.

Experienced RC technicians will find installation simple: remove the drive hub, note shim order and alignment, install the 35AX washer, then recheck axial play. Always rotate the assembly by hand to confirm smooth operation before final tightening and engine start-up.

While not a direct performance tweak, maintaining consistent spacer thickness affects driveline geometry and can indirectly contribute to smoother running and longer service life for engine-driven components.

How can I verify this part matches my hub dimensions?

Measure the washer inner diameter, outer diameter and thickness and compare with your existing spacer or hub bore. The OS23108000 is intended for assemblies that accept the 35AX form.

How often should I replace the washer?

Replacement interval depends on running hours and exposure to shock; inspect the washer during routine maintenance and replace if you see wear, burrs or bending.

Why use a dedicated washer instead of stacking shims?

A single, correctly sized washer offers repeatable thickness and better concentricity than a stack of mixed shims, which helps keep the driveline aligned and reduces uneven loading.
