Reassembly is carried out in the reverse order.

It is very important that the replacement part has the exact center distance length of the original part.
-
To check that the new part has the same center distance length as the original, simply place the 2 parts on top of each other and insert a screw into each center distance. If the screws go in, then the new part has the correct dimensions.
-
The thread used for the nut, the spindle and the bolts is not standardized, it is an M12 with a pitch of 1.5. 2 precautions are therefore necessary: lubricate abundantly and make sure when you screw that you are well in the axis.
