Clogging of Filters used in Hydraulic System - Due to Cellulosic Material
Clogging of Filters used in Hydraulic System - Due to Cellulosic Material
(OP)
Hi,
A particular filter that is in use for the Hydraulic System of an aircraft that i maintain, keeps on clogging. When we cut open the filter, we find that it is heavily clogged with a dark greyish substance. When we send the dark greyish substance to the Laboratory for examination, the laboratory told us that the substance is a cellulosic material. I'm puzzled because i'm not aware of such material being used in the Hydraulic System. Does anyone have a similar experience?
One possible suspect is the filter itself, but when I tried to look through the filter OEM's website, but there is no material of the construct of the filter there.
Thanks in advance, and regards
Ethan

The crack team of assemblers I worked with did that with the cooling system on a diesel, put a rag in a line to keep the coolant from dribbling or some such while servicing. I guess the rag got pushed back where it wasn't hanging out anymore. A 2 stroke supercharged diesel actually depends on cooling and rag as found throughout the heads.
Best of luck finding it. I'd start with any reservoir.
