Insert the keys into the shaft and slide the large
worm gear into place. Note: There is a large letter
“R” and an arrow on one side of the gear. This
gear MUST be installed such that the R and the
arrow are on the right hand side and the arrow is
pointing forward (Figure 30). This is a two piece
gear that is bonded together. If it is installed
backwards, the forces try to separate the gear and
can result in failure.
