CARRIAGE FEED GEARBOX DRAIN & REFILL
Make a card-stock Vee channel as described for draining
the headstock. Run the lathe for a few minutes to warm
the oil if necessary, then remove fill plug (2), Figure 4-2.
With the Vee channel in place, remove drain plug (3)
and allow the gearbox to empty completely. Replace the
drain plug. To refill the gearbox use a funnel attached to
a flexible plastic tube inserted into the fill hole. Add oil to
the halfway mark on the sight glass, Figure 4-4 (about
qt).
