Bosch Frame Sleeve Set - BDU31YY | BDU34YY | BDU38YY

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

Instead of frame sleeves, there’s now a new mounting concept using frame bushings (EB1190002H or EB1190002J) along with new matching screws (EB1190002F or EB1190002G) for installing the BDU31YY, 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 adaptor remains unchanged.

It's important to know that for the wide version of the Performance Line SX up to MY26 EB1110000X (BDU3143) / EB1110000Y (BDU3145), you should still use the screws from the old mounting solution (EB11900011) together with the new frame bushings (EB1190002H).
