Oil for lubrication is carried throughout the ramming system by the
action of the rammer. Holes drilled in the piston allow the oil to be
distributed from the bottom of the rammer to the crankcase. Oil in the
ramming system must be maintained at the correct level to ensure the
system operates efficiently.
Check oil level:
Check the oil level in the sightglass
(a)
daily before starting the
rammer. When checking the oil, make sure the rammer is on a flat,
level surface. The oil level should fill 1/2–3/4 of the sightglass. Add the
oil though the fill plug
(c)
located in the filter housing at the top of the
rammer. See section
Technical Data
for oil quantity and type.
Change the ramming system oil after the first 50 hours of operation
and then after every 300 hours of use.
Oil change:
5.7.1
Remove the oil fill plug
(c)
and the seal ring.
5.7.2
BS 500: Remove the sightglass.
BS 600/700/650, DS720: Remove the drain plug
(b)
.
5.7.3
Tilt the rammer back until it is resting on its handle.
5.7.4
Allow the oil to drain.
5.7.5
Wrap the sightglass threads with Teflon tape.
5.7.6
Reinstall the sightglass or the drain plug, and torque to 9.5 Nm (7
ft.lbs.).
5.7.7
Stand the rammer upright on a level surface.
5.7.8
Add oil through the fill plug. Proper ramming system lubrication is
indicated when approximately 1/2–3/4 of the sightglass is full.
NOTICE:
It may take some time for the oil to filter down to the
sightglass. Use care not to overfill the ramming system. Excessively
high levels of oil can create a hydraulic lock in the ramming system.
This can result in erratic operation and cause damage to the engine
clutch, the ramming system, and the shoe.
