Since August 2025, there has been a new mounting concept for the BDU31YY (Narrow variant, or wide variant including adapter), BDU34YY and BDU38YY drive units.

The frame sleeves used so far are being replaced by frame bushings. The frame bushings and associated bolts are backwards compatible with the drive units that were still installed with frame sleeves. The adapter remains unchanged.

It's important to know that for the wide version of the Performance Line SX up to 2026 EB1110000X (BDU3143) / EB1110000Y (BDU3145), you should still use the screws from the old mounting solution (EB11900011) together with the new frame bushings (EB1190002H).

Comes supplied in a pair.
