Before you start:
• Remove he motor cover (See Section 4.2.9).
(1) Hold the DynaTilt motor gear so that it cannot move.
(2) Move the quadrant assembly up and down while you examine the play between
the gear teeth (see Figure 4.52).
There should be 0.1mm of gear play.
(3) Use your hand to rotate the DynaTilt motor gear.
The DynaTilt mechanism must operate smoothly with no stiffness or free-play.

Pivot Screw
DynaTilt Drive Motor
Figure 4.53 DynaTilt Drive Motor
The top LH screw that attaches the DynaTilt drive-motor to the LH side plate is installed
through a clearance hole (a circular hole that has a slightly larger diameter than the
diameter of the screw). This screw is known as the pivot screw (see Figure 4.53).
Each of the three remaining screws that attach the DynaT
ilt drive-motor to the LH side
plate is installed through a radial slot (a curved slot that moves around the radius of a
fixed point). This means that the DynaTilt drive-motor can be turned around the pivot
screw to increase or decrease the amount of gear play between the DynaTilt motor
gear and the quadrant assembly.
Tools:
• Allen Key: 4mm.
