Precision Fit: XRAY 388540 Brass Flywheel Collar

The XRAY 388540 Brass Flywheel Collar is a precision machined item that secures the #388531 flywheel to NT18 series crankshafts, helping to maintain true rotation under load. Constructed from brass, it is intended to provide consistent seating and extended service life in competitive use.

Main Features and Uses

  • Material: Brass for reliable durability and consistent mating surfaces
  • Compatibility: Specifically made for NT18 and NT18T engine crankshafts
  • Function: Keeps the flywheel mounted securely to prevent slippage
  • Application: Ideal for competitive track applications and frequent running
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 does the XRAY 388540 improve flywheel retention?

By providing a tight, accurately machined seat between the flywheel and crank, the collar reduces movement and helps maintain balance at high RPM.

Is any preparation needed before fitting the collar?

Clean the crank and flywheel bore to remove oil or debris, then fit the collar squarely before tightening to the recommended torque to ensure correct seating.

Can this part be used as a replacement for worn collars?

Yes, it is suitable as a direct replacement where the original dimensions match; replacing a worn collar restores secure flywheel mounting and reduces play.
