Lubrication and Maintenance
15" SEED OPENER DISC bLADE/
bEARING ASSEMbLY
Approximately 1" ± ½" of blade-to-blade contact
should be maintained to properly open and form seed
trench. As blade diameter decreases due to wear, it is
necessary to relocate machine bushings from inside to
outside to maintain 1" ± ½" of contact.
NOTE: Proper blade clearance is critical. blades
should have 1" ± ½" contact in this area. When
blades are turned by hand in opposite directions
against each other, there should be only light
resistance to turning. Re-adjust blade scraper if
necessary to center it between the blades.
NOTE: If proper blade-to-blade contact cannot be
maintained after relocating machine bushings or if
blade diameter wears below 14½", blades should
be replaced.
NOTICE
Excessive blade contact may result in premature
disc opener bearing/hub failures and excessive
wear on seed tube guard/inner scraper. When
properly adjusted, if one blade is held in fixed
position, opposite blade should rotate with less
than 5 pounds force at outer edge of blade.
REPLACE DISC BLADE/BEARING ASSEMBLY
1. Remove gauge wheel.
2. Remove scraper.
3. Remove bearing dust cap.
4. Remove cap screw, washer and disc blade/bearing
assembly. Machine bushings between shank and disc
blade are used to maintain approximate 1" ± ½" of
blade-to-blade contact.
NOTICE
Left hand side of opener uses a left hand threaded
cap screw. DO NOT OVER TIGHTEN. Damage to
shank threads require replacement of row unit
shank assembly.
5. Install machine bushing(s), new disc blade
bearing assembly, washer and cap screw.
Torque
⅝
"-11 Grade 5 cap screw to value shown
in “Torque Values Chart”.
NOTE: Replace disc blades only with disc blades
of equal thickness.
6. Replace bearing dust cap.
7. Install scraper.
8. Install gauge wheel.
It may be necessary to replace bearing only if there is
excessive endplay or if bearing sounds or feels rough
when disc blade is rotated.
REPLACE BEARING ONLY
1. Remove gauge wheel, scraper, bearing cap, cap
screw, washer and disc blade/bearing assembly.
2. Remove
¼
" rivets from bearing housing to
expose bearing.
3. After installing new bearing, install three evenly
spaced
¼
" cap screws into three of six holes
in bearing housing to hold bearing and bearing
housing in place. Install rivets in other three
holes. Remove ¼" cap screws and install rivets
in those three holes.
4. Reinstall disc blade/bearing assembly, washer
and cap screw. Torque ⅝"-11 cap screw to value
shown in “Torque Values Chart” at the beginning
of this section.
5. Replace bearing dust cap.
6. Install scraper and gauge wheel.
Approximately
