Lubrication
Every 150 hours of operation grease front axle pivot pins (1-Fig. 5.6.4) and kingpins (1-Fig. 5.6.4)
grease points.
Check the oil level in the front axle housing (2-Fig. 5.6.3) and clean the breather (2-Fig. 5.6.4)
of the
front axle every 150 hours of operation.
To check, remove the filler / level plug (2-Fig. 5.6.3). The oil should reach the edge of level hole.
To clean the oil breather, remove it, clean in fuel oil and allow it to dry. Tighten it to a torque of 10 Nm.
Replace the oil in the front drive axle housing every 600 hours of operation plug (2-Fig. 5.6.3) short
after tractor stop. The drain plug (3-Fig. 5.6.4) is located at front of the front axle housing.
Check the oil level in the epicyclical reduction units of front drive axle every 150 hours of operation.
To check, set the wheel hub with the filler/level, drain plug 1-Fig. 5.6.6) in horizontal position as
indicated by the line (2-Fig. 5.6.6) and remove the plug. The oil level should reach the hole level.
Replace the oil in the front final drive housing every 600 hours of operation or once a year, whichever
occurs first.
To replace, proceed as follows (Fig. 5.6.6):
set the plug in its upper position and then loosen it to release possible internal pressure,
set the plug in its lowest position and remove it,
after draining the oil, set the plug in horizontal position as indicated by the line and fill the
system with a fresh oil of recommended grade up to the level of the plug hole. For capacity, see
Table 7.
fit the plug and tighten to a torque of 80 Nm.
