OIL LEVEL
–
Each wheel hub should maintain a proper oil level at all
times. Less than that would limit lubrication and over full would cause over-
heating and damage. To check the oil level, position the hub so one of the
face plugs is positioned at 12 O’clock (fig. 115-1, item A). The other plug
will be either at 8 O’clock (fig. 115-1, item B). (When positioned correctly
the arrows in the center of the hub should make an “L”.) Remove the lower plug; if no oil comes out, the oil
level is too low. Check wheel hub oil level every 100 hours.
If SAE 80W/90 or SAE 85W/140 with EP features oil is needed, remove the top plug also and fill just until it
starts to come out the lower hole (approximately 40 ounces). With the oil at a satisfactory level, re-install plugs.
CHANGE
–
The wheel hub oil should be changed after the first 50 hours of field operation. Subsequently,
it should be changed every 500 hours or yearly (whichever comes first).
To change the wheel hub oil, position the plugs so that one is at the 6 O’clock position, and the other is
between the 2 and 3 O’clock positions. Remove the bottom plug to drain the oil. Once all of the oil is drained,
rotate the hub so that the plugs are in the filling position (fig. 115-1). Refill wheel hub with gear oil as described
above.
GENERAL MAINTENANCE-
If your sprayer is going to sit for an extended period of time, occasionally
rotate the hubs by driving the sprayer forward and backward at least 1/2 of a tire rotation to adequately coat all
internal hub parts. This will prevent rusting if moisture inadvertently entered the hub during an oil change. Fail-
ure to rotate the hub and disperse oil may cause rusting and internal damage to the hub.
