LUBRICATION BOX
The C-30HDNI model features a fully enclosed
lubrication
box, which utilizes the "SPLASH" method of lubrication.
Before using your new pump, 7 gallons of SAE 30 motor oil
must be added directly into the lubrication box. Make sure the
pump is on a secure level surface when checking the oil level
inside the lubrication box.
Visually inspect the oil in the
lubrication box (Figure 25) by
making sure the oil is at the correct
operating level as indicated by the
dip stick. Also reference the oil level
decal (Figure 26) adjacent to the
lubrication box.
CAUTION
The oil level must be
checked daily to
ensure adequate oil level and oil
cleaniness.

PISTON HEAD LUBRICATION
The
rubber piston cups are a natural wear component and
will require periodic replacement. The life of the rubber cups
depends on many factors, proper oil level, oil cleanliness,
abrasiveness of aggregrate being pumped and material slump
etc.
IMPORTANT!
To ensure maximum cup life, the oil
level in the lubrication box
must be
maintained at the proper level. In
addition the lubrication box must be
cleaned periodically.
As the rubber piston cups wear, fine cement particles will
accumulate in the bottom of the lubrication box. Once this cement
paste reaches 1-inch in height, it is recommended that the
lubrication box be drained (flushed) and cleaned and the oil
replaced with new SAE 30 motor oil.
There are two clean-out ports
located at the bottom of the lubrication
box.
Any questions regarding the lubrication box clean-out
procedure, contact the MAYCO Service Department.
