Central greasing systems are sometimes seen on lorry chassis.

A further problem if incompatible greases are used, they can harden and clog 
the lines when they mix. (Ask me how I know this.)

It is an old machine. There is a bowl filled with grease connected to a row of 
pneumatic valves so I guess the grease is supposed to enter this block. There 
is also plenty of tubes connected to blocks on the sliding surfaces and I could 
see there are grease on the sliding surfaces. It all seems to be driven by 
pneumatic and I have connected compressed air. One of the valves are marked 
lubrication and I have tried to switch this but nothing seems to happen.


Bijur central lube systems use way oil, not grease.  Grease takes a lot 
of pressure to send through thin tubes.  Bijur and similar central lube 
systems have metering orifices that get clogged when the system sits for 
a long time.  I have not had any luck cleaning them.  Direct from Bijur, 
they are surprisingly inexpensive.  If this is truly designed for 
grease, then I really don't know anything about it.

I don't know this application but in all the cases I have seen the 
grease is a light #1 NLGI grease for bank systems. The usual grease gun 
grease is #2. #2 is used for bearings and farm machinery, #1 is used a 
lot in reciprocating applications, like presses and such. DO NOT SUBSTITUTE.
