9.5.2 Re-assembly of DON-x20...DON-x40
Both oval gears are placed on the axle shafts with the magnets oriented towards
the upper meter body (4). Verify that the axle shafts are not loose. Both oval gears
are equipped with embedded magnets, allowing them to each be mounted on either
axle.
Install the rotors exactly perpendicular from each other (90° in orientation). They
will only work if installed precisely. Manually test full rotation after installation as
the rotors will not completely rotate freely unless installed precisely 90° from each
other.
Proper placement of the O-ring within the groove is necessary for leak free
operation. After placement, items (1 & 4) will then require assembly.
Tighten the upper meter body to the lower meter body (1 & 4) with the screws (5)
in an alternating pattern (1, 3, 2, 4). Tighten to each to a torque according to table
chapter 9.5.2. The alternating tightening procedure is preferred for proper and even
assembly.
Install the pulse detector board, the o-ring into the provided groove, and then install
either the electronic cover (9) or optional electronic assembly.
