Section 1: Assembly & Set-up
Quick Change Rotor
Use an overhead hoist for rotor installation.Attach chain, cable, or
lifting strap to the two Overseeder sling brackets and raise
Overseeder with the overhead hoist.
Refer to Figure 1-2:
Complete steps 1 to 4 if the Overseeder is equipped with gauge
wheel drive. Skip to step 5 if gauge wheels are not included.
1. Remove chain cover (#1) on the right-hand side by removing
1/4" x 1/2" long bolts (#2).
2. Disconnect right-hand spring loaded gauge wheel link (#3)
from right-hand gauge wheel arm (#4) by removing
5/8" x 2 1/2" bolt (#5) and 5/8" nut (#6).
3. Remove drive wheel chain.
4. Remove cotter pin (#7) that retains the right-hand gauge
wheel arm and remove gauge wheel arm assembly. Be
careful not to loose any components.
Refer to Figure 1-3:
5. Remove right-hand bearing mount plate (#1) from
Overseeder main frame.
6. Separate right-hand bearing cover (#2) from right-hand
bearing mount plate (#1).
7. Between parts (#1 & #2) are two bearing mount gaskets (#4).
Place one of these bearing mount gaskets between bearing
mount (#3) and bearing mount plate (#1).
8. Then place the other bearing mount gasket between bearing
mount plate (#1) and bearing cover (#2).
9. Retain these parts with 1/2" x 1 3/4" long bolts (#5), 1/2" lock
washers (#6), and 1/2" hex nuts (#7). Hand tighten nuts at
this time. Final torquing of these bolts will be later in the
assembly process.
10. Check to make sure set screws in the hub inside the bearing
mount (#3) are loose so it is free to rotate on the rotor shaft.
Refer to Figure 1-4:
11. Lift Overseeder high enough to roll rotor into position under
the Overseeder frame.
12. With rotor properly positioned, slowly lower Overseeder
making sure the right-hand bearing mount plate (#1) is to the
outside of the right-hand frame end panel.
Refer to Figure 1-5:
13. Connect rotor to rotor drive hub (#1) on the left-hand side
using 7/16" x 1" long bolts (#3) and 7/16" lock washer (#2).
Leave bolts loose.
Refer to Figure 1-4:
14. Connect right-hand bearing mount plate to the Overseeder
main frame using 1/2" x 1 1/4" bolt (#2), 1/2" lock washer
(#3), and 1/2" hex nut (#4). Draw nuts up snug, do not tighten.
15. Torque bolts to the proper specifications, see "Torque Values
Chart" on page 61. Tighten bolts in the following order:
a. Rotor to rotor drive hub.
b. Bearing mount plate to Overseeder main frame.
c. Bearing cover through bearing mount plate to bearing
mount.
