Central lubrication system – bleeding and removal of blocks
521 / 564
Some distributors are provided with a lubricating nipple. This lubricating nipple is used
to simplify troubleshooting.
All lubrication points of the subdistributor 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 346). 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.
