7.2 Venting an oil progressive system
- See Figure 39
A requirement for venting an oil progres-
sive system is that the system has already
been fully assembled.
• Slightly loosen the main lubrication line
on the hand pump or pump unit, actuate
the pump/pump unit until bubble-free oil
discharges at the main lubrication line.
• Retighten the main lubrication line at the
pump.
• Slightly loosen the main lubrication line
on the main metering device, actuate the
pump/pump unit until bubble-free oil
discharges at the main metering device.
• Retighten the main lubrication line at the
main metering device.
• Slightly loosen the main lubrication lines
of the main metering device at the out-
lets, actuate the pump/pump unit until
bubble-free oil discharges at the outlets.
• Retighten the lubrication line at the main
metering device.
• Repeat venting at the secondary lubrica-
tion lines, secondary metering devices,
and lubrication lines.
• An additional venting as described be-
low is necessary if problems occur while
venting the metering devices (air still in
the device, too little lubricant discharge).
VP and VPK progressive metering devices:
• Loosen the right and left plug screws at
the last metering section as viewed
from the metering device outlet.
• Actuate the pump/pump unit until bub-
ble-free oil discharges at the plug screws.
• Retighten the left and right plug screws.
VPB progressive metering devices:
• Loosen the right and left plug screws at
the first metering piston as viewed from
the metering device outlet.
• Actuate the pump/pump unit until bub-
ble-free oil discharges at the plug screws.
• Retighten the left and right plug screws.
