3-6.5 Disassembly of Tine Chain Case. Disassem-
ble as follows:
1.Remove chain case from tiller.
2.Remove self-tapping screws, hex bolts, lock
washers and hex nuts from the outer edge of
chain case.
3.Remove hex bolt, lock washer and hex nut
from the center of chain case.
4.Remove self-tapping screws from bearing
housing. See Figure 3-63.
5.Slide bearing housing and bearing off input
shaft.
6. Separate the halves of chain case housing to
obtain access to reduction chains. Be careful
not to damage chain case gasket. Replace if
necessary. See Figure 3-64.
NOTE
The drive system has 2 chain reduction steps.
Each step reduces the speed and increases
the torque or power down to the axle shaft. The
reduction is done with the use of a #35 chain to
a #50 chain.
NOTE
The chain case is lubricated with 12 ounces of
plastilube #0 grease to keep the bearings and
chains operating in a constant lubrication bath.
7.Push input shaft inward slightly. Lift up on hub
sprocket assembly and remove #35 chain from
sprocket. This will allow slack in the other
chain which can be removed by lifting off the
sprockets. The hub sprocket assemblies will
also be removed from the housing during this
procedure. See Figure 3-65.
8.To disassemble hub sprocket assembly, slide
spacer out of bearing. On an arbor press
remove bearing by placing a spacer or similar
tool on the OD of bearing and press out. See
Figure 3-66.
