2.7 Lubricating gearboxes, axes 2 and 3
• Remove the filler (1) and drain (2) plugs. See Figure 7.
• Grease through the filling hole (1).
• The axes 2 and 3 must be moved slowly backwards and forwards several times while
greasing.
• Continue greasing until new grease exudes from the drain hole (2). See Volume below.
• Move the axes backwards and forwards a couple of times before the plugs are
replaced, so that excess grease is pressed out. This is to prevent over-pressure in the
gearbox with risks for leakage.
Volume:
- 1.2 litres (0.33 US gallon).
- About 2.0 litres (0.82 US gallon) should be used when changing the grease.
Type of grease:
- ABB 3HAC 2331-1 Molywhite RE No 00
Tools: See Tool list.
Figure 7 Drain holes, axes 2 and 3.
