7.25 Rear Wheel
NOTE:
Rear wheel wear drive plates (M)
should be rotated prior to wear in the wheel
weldment.
7.25.1 Wheel Speed/Conveyor Speed
The wheel and conveyor speed flow controllers are
shown in Figure 7
-
43.
To increase the speed of either component, move the
switch in a manner such that the corresponding num-
ber increases. Likewise, decreasing the number will
decrease the speed.
7.25.2 Wheel Drive Chain Tension
To adjust the wheel drive chain tension:
1.
Shift to park, disengage the PTO, lower the machine to the ground, relieve hydraulic pressure,
stop the engine, remove the ignition key, and wait for all moving parts to stop before dis-
mounting.
2.
Tighten nut (A), shown in Figure 7
-
44, until at de-
sired chain tension.
If the spring is fully compressed and more chain ten-
sion is required:
1.
Loosen nut (A) until the spring is not under com-
pression.
2.
Remove nut (B) and the bolt. Line up the second
hole from the top with the arm linkage. Replace
the bolt and tighten nut (B).
3.
Tighten nut (A) until at desired chain tension.
