5.8 Ramming System Lubrication (BS 50/60/70, BS 65, DS 70)
Background
Lubricating oil is distributed throughout the ramming system by the
action of the rammer. Holes drilled in the piston carry oil from the
bottom of the rammer to the crankcase as the rammer operates. Oil in
the ramming system must be maintained at the correct level to ensure
the ramming system operates efficiently.
Checking the oil level
Perform the following procedure to check the ramming system oil
level.
Note: If the Rammer has been transported in the horizontal position or has
recently been used, upright it and allow it to stand in the upright position for
15 minutes before checking the oil level. This will allow the oil to settle and
provide a more accurate reading.
5.8.1 Tip the rammer so that it is perpendicular with the ground.
5.8.2 Check the oil through the sightglass
(a).
The correct oil level will fill 1/2 to 3/4 of the sightglass. Add more oil if
necessary.
Adding oil
Perform the following procedure to add oil to the ramming system.
NOTICE: Do not overfill the ramming system with oil. 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.
5.8.3 Tip the Rammer forward to allow access to the sightglass. Secure the
Rammer in this position.
