Section 4: Maintenance & Lubrication
16.Apply a coat of grease to the seal and press bearing housing assembly onto the rotor shaft, taking care not to damage the seal. Reinstall snap ring.
17.Install rotor to the Overseeder by reversing steps 2 through 4.
Rear Roller Maintenance
Refer to Figure 4-7:
Rear roller wheels (#14) should rotate freely over wheel mounting tube (#15) and have a small amount of lateral movement between the two end plates (#12). This loose fit allows for the rollers to turn independently from each other which keeps debri from locking them up and allows the seeder to turn corners without pushing dirt in front of the rollers.
Rear Roller Inspection
Inspect roller wheels daily to make sure they are turning and not pushing dirt. Your should be able to hold one roller still while rotating the roller next to it with your hand. If this cannot be done, then the rollers should be cleaned of debri that has impacted between them.
Over time, the roller wheels will wear against each other and become loose moving back and forth laterally on the mounting tube. Spacers, 1/4" in width, should be added on the left end to take up excessive slack and to extend the life of the roller wheels and mounting tube. Also, the roller wheels should be inspected for breakage. Broken rollers should be replaced as soon as possible.
Inspect roller wheels for wear by sliding all rear roller wheels (#14) and end spacers (#13) to the right and then measure the gap on the left end. If gap between last end spacer (#13) and end cap (#12) is 3/8" or greater, then an additional 1/4" spacer or spacers should be added to the mounting tube. Never add too many spacers. Too many spacers will force the roller wheels tight against one another and won’t allow them to turn independently.
Rear Roller Disassembly
Disassemble rear roller mounting tube from Overseeder as follows:
NOTE: During disassembly, set aside all loose components and hardware in an orderly fashion and in a safe location for relocating and reassembling.
1.Lower Overseeder and rear roller to ground, shut tractor off, set park brakes and remove switch key.
2.Disconnect packer chain (#6) or turnbuckle (#7) from the left hand rear roller arm (#16).
3.Remove 3/8" bolts (#4) and scraper bar (#5) from left and right rear roller arms (#16).
4.Remove 3/16" cotter pin (#8) and clevis pin (#9). Lower front of left rear roller arm (#16) to the ground.
5.Loosen set screw in eccentric locking collar of bearing (#10) and then rotate eccentric locking collar counterclockwise. This should free the shaft from the bearing.
6.Remove rear roller arm (#16) with attached bearing (#10) from rear roller mounting tube (#15).
7.Remove flat washer (#11) and end cap (#12).
Rear Roller Assembly
1.Replace roller wheels (#14) and/or add 1/4" spacer rings (#13) as needed on the left side of the seeder:
Roller Wheels
a.Remove roller wheels (#14) from mounting tube (#15) until you reach the broken roller.
b.Replace broken roller with new roller and reinstall removed roller wheels.
Spacer Rings
a.Add spacer rings on the end of the mounting tube until gap measured in paragraph of “Rear Roller Inspection” is almost but not quite filled.
2.Replace end cap (#12) and flat washer (#11) on shaft of mounting tube (#15).
3.Insert shaft of mounting tube (#15) fully into bearing (#10). Turn bearing eccentric locking collar clockwise and then tighten set screw in locking collar.
4.Reattach rear roller arm (#16) to seeder panel with 1" clevis pin (#9) and 3/16" cotter pin (#8). Be sure to bend one leg of cotter pin to secure it in place.
5.Insert stop pin (#7) in seeder bracket and secure with hairpin cotter (#6).
6.Reattach scrapper bar (#5) to left and right rear roller arms (#16) with
7.Reattach packer chain (#6) or turnbuckle (#7) to rear roller arm (#16) with remaining hardware.
