Central lubrication system – bleeding and removal of blocks
8.13 Central lubrication system – bleeding and removal of blocks
Lubricat-
ing pump
→ Main distributor →
Sub-distributor → Lubricat-
ing point
During all work on the central lubrication system, make sure of utmost cleanliness. In
no case should dirt enter the lubrication system.
Should the grease reservoir inadvertently have been run empty, then the grease pump
must be bled. For this purpose, remove the main pipe from main distribution and
switch on the pump for so long until air-free grease emits from the main pipe. Screw a
lubricating nipple into the input of the main distributor and using the grease gun, pump
grease into the main distributor for so long until grease emits at the bearings. Then,
reconnect all pipes.
If the pipe system is blocked, then the grease will be pressed out at the safety valve
(

) (directly at the pipe output of the pump). To remove this block, proceed as follows:

– Search for the blocked spot in the pipe system. Go along the stiffer grease pipe
from the lubricating pump through to the main distributor (the blocked pipe is stiffer
because it is under pressure) further to the corresponding sub-distributor and from
there to the blocked lubricating point. You can find a detailed plan in chapter 9.
– Disconnect the pipe from the distributor and screw a lubricating nipple into the cor-
responding (sub) distributor.
– Try to loosen the block strongly pressing grease into the distributor using the hand
lever grease gun.
– Proceed systematically: from the grease pump to the main distributor, from there to
the sub-distributor, etc..
– Once you determine that the line is permeable again, connect the line with the con-
sumer. Check the free passage by performing an intermediate lubrication.
– Shouldn't the method prescribed here lead you to any success, please contact your
ROPA service station.
Some distributors are provided with a lubricating nipple. This lubricating nipple is used
to simplify troubleshooting.
All lubrication points of the sub-distributor can be supplied with grease via this lubricat-
ing nipple, because there is a check valve in the outlet of the main distributor.
There is no check valve between the lubrication pump and the main distributor.
The main distributors can be recognised by the integrated lifting pin indicator (
See
Page 347
). Should you feel only slight resistance when greasing the lubricating nip-
ple at the main distributor, then the grease can flow freely into the grease reservoir of
the central lubrication pump. In this case the wing in central lubrication pump must be
turned by approx. 120° via manual intermediate lubrication.
