3-2.5 Disassembly of Tine Chain Case. Proceed
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

Figure 3-12.
5.Slide bearing housing and bearing off input
shaft.
6.Separate halves of the chain case housing. Be
careful not to damage the chain case gasket.
Replace if necessary.
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 #420 chain.
7.Push input shaft inward slightly. Lift up on hub
sprocket assembly and remove the #35 chain
from the sprocket. See Figure 3-13.
NOTE
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 proce-
dure.
8.To disassemble the hub sprocket assembly,
slide the spacer out of the bearing. On an
arbor press place a spacer or similar tool on
the OD of the bearing and press bearing out of
hub sprocket assembly. See Figure 3-14.
