Bosch Frame bushing kit, wide (BDU31YY, BDU34YY, BDU38YY)
<p>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.</p> <p>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.</p> <p>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).</p> <p>The following <a href="http://training.b2b.bosch-ebike.com/sui/itemDetail/10854?context=1&catId=10350&asId=0&tpId=0&tpeId=0" target="_blank">assembly video</a> contains all the important information.</p>

Please note: This frame bushing set is suitable for installing the BDU31YY, BDU34YY and BDU38YY drive units with wide mount. These frame bushings may only be installed with the corresponding bolt set EB1190002G for wide frame bushings (BDU31YY, BDU34YY, BDU38YY). The wide version of the Performance Line SX up to MY26 EB1110000X (BDU3143) / EB1110000Y (BDU3145) should still be installed using the screws from the previous mounting solution (item no.: EB11900011) together with the new frame bushings (EB1190002H).
