Filler / Oil Gauge / Drain Plug Locations
All IronHorse helical gearboxes have six (6) filler/oil gauge/drain plugs. The six plugs are located in
different locations depending on the actual box size selected. Filler / gauge / drain plug locations,
are shown below. Units are shipped configured for an M1 mounting position. Refer to the section
MOUNTING POSITIONS in this chapter to see the location of the filler / gauge / drain plug
locations for each different mounting position. If the mounting position is changed, the oil drain
plug should always be placed in the lowest position after a new mounting position is selected.
The
Recommended Lubricant by Box Size and Mounting Position table in this chapter lists the
proper amount of oil for each mounting position. Oil fill amount is listed in liters.
When filling the gearbox with oil remove the oil gauge plug. Add oil until it begins to come out of
the oil gauge plug. Replace the oil gauge plug and the fill plug. The gearbox now has enough oil
inside.
When changing the oil, it may not be possible to remove all of the existing oil without
disconnecting and lifting the unit. If lifting the unit is possible, simply lift the unit with proper
lifting equipment, lower the drain plug by tilting the unit sideways, and gently shake the unit until
all of the existing oil is removed.
The white cap shown below is a breather plug and should always be located in the filler position
on the gearbox. If the gearbox is used in a position other than M1, the breather plug will need to
be moved to the filler position after the new mounting is completed.
NOTE: The breather plug should always be placed in the filler position.
When filling the gearbox with oil, remove the breather plug, fill the oil
and re-install the breather plug.
