Checking and Changing the Ramming System Oil

Background Lubricating oil is distributed throughout the ramming system by the vibrating 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 that the ramming system operates
efficiently.
Checking the Perform the following procedure to check the ramming system oil level.
oil level
Note: If the rammer has been transported in the horizontal position or has recently
been used, place it upright 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.
1. Tip the rammer so that it is perpendicular with the ground.
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.
1. Tip the rammer forward to allow access to the sightglass. Secure the rammer in
this position.
