Hi. Im trying to replace the frame bushes in my 2024 mondraker dune with a bosch BDU3145 sx motor.
I contacted my local bosch dealer and ordered the updated bushes for my frame/motor but the ones supplied are incorrect. Ive been supplied a narrow and a wide bush and a short and a long bolt with a small step. One of rhe new bolts have a much longer head than the other.
My frame uses two narrow bushes and a long and a short bolt with the same lengh head.
Ive since found info that on the sx motor I use use the original bolts and not the updated ones with the step . Can anyone else confirm this?
Also the original bush has a lip either side whixh locates its in the frame. The new bush doesnt. Its a loose fit in the frame bit a tight fit ln the original bolt. Om guessing once fitted the bolt goes into the new bush, which then expands into the frame hole?
