Overview: crankshaft for 50ST series

This YS Engine YSS1011 crankshaft is offered as a spare specifically for 50ST-marked scale RC engines, focusing on fit and installation rather than broader cross-compatibility. Check your engine's documentation to confirm it matches the 50ST designation.

As the rotating assembly core, the crank requires correct bearing fitment, accurate end-play, and proper lubrication. During installation, ensure journals are clean and bearings are seated correctly to avoid premature wear.

In a tuning or rebuild scenario, treat this crankshaft as a mechanical interface component: inspect for runout, verify journal condition, and confirm secure connection to the connecting rod when reassembling the engine.

Fit the YS Engine YSS1011 crankshaft when servicing a 50ST-designated engine, verifying bearings, clearances, and following recommended lubrication and break-in steps.

Can this crankshaft be balanced for high-RPM use?

Balancing should only be done after confirming the YS Engine YSS1011 dimensions match your set-up; consult a machinist for dynamic balancing recommendations.

What tolerance checks matter most?

Measure journal runout, verify bearing bores, and check end-play margins against the engine manual to ensure safe operation.

Should I replace bearings when fitting this part?

It is good practice to inspect and often replace bearings and seals during a crank swap to prevent future failures.

How do I confirm keyway engagement?

Verify the key seats flush and the connecting rod is clamped correctly; any play at the keyway can lead to accelerated wear.
