Prepare Meter Sense Ports
Refer to Figure 147, Figure 148 and Figure 149
Sense lines are connected from the chamber
to
5 or 6 meters. Sensing rows are:
329. Inspect the left side of all row units.
If all meters at the correct rows already have
adaptor
fittings installed at their sense ports ,
continue at “Connect Meter Sense Lines”.
If incorrect rows have adaptors, exchange the adap-
tors with plugs
at the correct rows, and con-
tinue at “Connect Meter Sense Lines”. See
step 330 to step 332 for exchange instructions.
If no rows have adaptors , continue at step 330.
330. At each Sensing Row from the table above, where
an adaptor is to be installed, remove:
817-829C PLUG, FLUSH HEAD POLYETH 7/16
This plug is located at , above the drive sprocket,
in between the air and seed elbows. Remove the
meter rain cover, and any seed disc present. Use a
small blunt punch to push the plug out from the
sprocket side. Unless needed where an adaptor is
removed, this plug is not re-used.
331. At each incorrect row, where an adaptor is installed,
remove and save one set:
803-374C NUT HEX JAM 7/16-20 PLT
891-122C AD 7/16MORB X 1/4HB BRASS
332. At each sense line row, select one set:
803-374C NUT HEX JAM 7/16-20 PLT
891-122C AD 7/16MORB X 1/4HB BRASS
Insert the threaded end of the adaptor , from the
sprocket side, through the sense port of the
meter. Secure with jam nut .
Connect Meter Sense Lines
Refer to Figure 146 on page 73, and Figure 149
333. Select two:
800-395C CLAMP SPRING BAND 1/2 OD HOSE
and the coil of:
990-021R HOSE 1/4 RUBBER AIR
Place a clamp on one end of the hose .
Connect that end to the top available adaptor
fitting
on the sensor chamber . Route the
hose along the air manifold, and then along the
supply air hose at the row, to the fitting
at the
meter port . Cut the hose to length. Secure
hose to fitting with clamp .
