Bosch Drive Unit Screw Kit, narrow - 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.

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.

This bolt set is suitable for installing the BDU31YY, BDU34YY and BDU38YY drive units with narrow drive unit mount.

These bolts may only be fitted with the corresponding frame bushing set EB1190002H.
