Replace Gauge Wheel Caster and AntiRotate Pins
Refer to Figure 2
NOTE: To replace gauge wheel caster and
and anti-rotate pins, the gauge wheels
will need to be blocked up so the weight
is off the tires. Blocks should have a minimum support capacity of 4 tons.
1. Once unit is blocked up and weight is off
tires, remove tire (4) from hub (3). Remove bolt (10) and lock nut (9) securing
spindle to caster. Slide spindle (2) and
hub (3) out of caster (7).
2. Remove bolt (5) and lock nut (1) securing vertical shaft caster (6) to caster (7).
Caster (7) and pivot thrust washer (8)
should fall to ground. Discard caster (7).
Keep pivot thrust washer (8) for reuse.

Replace Idlers
Refer to Figure 4
1. Detach meter from opener and set meter aside.
NOTE: It is not necessary to detach hose
from meter.
2. Detach spring from idler bracket weldment. Remove snap ring (4) from front idler (10). NOTE: It
is not necessary to remove both snap rings.
Discard snap ring (4). Keep spring for reuse.
NOTE: If meter drive units have been timed for
staggered drop on twin row spaced planters, do
not remove drive chain from sprocket without
first noting which sprocket tooth is up. Check
that sprocket is timed with same tooth up when
chain is reinstalled or re-time meters when finished according to the instructions in operator’s
manual.
3. On backside of drive mount weldment (2), remove bolt (6) and washer (8) securing idler pivot
(3) and idler bracket weldment (1) to drive mount
weldment (2). Keep bolt (6) and washer (8) for

5. Turn sprocket by hand for two rotations. Insert
meter drive adapter tool into hub of sprocket.
NOTE: To test torque, remove chain from
sprocket. Complete test with parts at temperatures of 65 degrees or higher. Using 5/8"
socket and an inch-lb torque wrench, measure
drive torque by rotating sprocket in normal direction of travel.
NOTE: Meter drive units with torque readings in
excess of 10 inch-lbs should be replaced. Units
with torque variation, as sprocket is rotated,
greater than 3 inch-lbs should be replaced. Order assmebly 403-117s, one per row as needed.
NOTE: It is not necessary to completely remove
chain from row unit while replacing idlers.
6. Secure idler pivot (3) and bushing (9) to drive
mount weldment using bolt (6) and washer (8)
removed in step 2.
NOTE: DO NOT apply any lubricant or anti-sieze
compounds to these parts when reassembling.
