The EZD 52 pinion is in two sections!
Due to this unique design, the EZD 52 can be installed "around the drive shaft". This means that installation no longer involves sliding the unit right down the entire length of tube. Instead, the housing slides radially onto the pinion and the drive shaft, snaps into position and holds the two halves of the pinion together. Then the rack can slide into position and be secured in the normal way.
