Crown Replacement Battop for 309, 307, 303 Series: Clear Blue

Disclaimer: DX Bobbin manufactured after June 2024 Not Compatible with Crown Replacement Battop or JLF Conversion Shaft

We recently learned that a Crown 309 DX Bobbin for Tension Grommet that is manufactured after May 2024 does not fit any Crown Replacement Battop for 309, 307, 303 Series nor our Crown JLF conversion shaft. These products have a shaft diameter of 7.6mm with a +- .1mm tolerance.  Before June 2024, the DX bobbin was 7.8mm.  Without prior warning, Samducksa/Crown reduced the bobbin inside diameter to 7.7mm, leading to fit discrepancies with our these products. It will fit the current version of the Crown CWL bobbin, however. If you don't already own this bobbin, you'll want to bundle it with your purchase of this product.

Until Samducksa possibly reverts the DX Bobbin back to 7.8mm, we are offering the Crown 309-CWL Bobbin for Tension Grommet as a free pack-in with the Crown CWL-309-MJ-NEW-Helpme-KMS-ST30 Joystick. This chart explains the current discrepancy.

This Crown/Samducksa Replacement Battop is compatible with Crown 309, 307, and 303 Series joystick levers, including the Crown CWL-309-MJ-NEW-Helpme-KMS-ST30 Joystick.

Does not come with E-Clip. Use Existing or Bundle Spare E-Clip with Purchase. 

Please note that if you already own one of these Samducksa levers, please use e-clip and dustwasher from your existing lever to install. Alternatively, you can purchase the E-Clip for Crown 303/307/309 Series Joystick if you need a spare.
