Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How should I install the XRAY 388550 nut?

Thread the nut onto the crankshaft so it seats against the #388531 flywheel, then tighten securely with the correct spanner. Inspect the fit after the first run and recheck periodically during maintenance.

Is the XRAY 388550 suitable for other engine types?

The nut is designed for NT18 and NT18T engines. While it may fit similar crankshaft designs, compatibility with other engines is not guaranteed without checking the shaft profile and thread.

How do I inspect the nut for wear?

Check the threads for burrs or corrosion and ensure the nut remains tight after running. Replace the nut if the threads are damaged or if it no longer holds the #388531 flywheel securely.
