it looked to be 1/8" or a little more in the bottom.
it seems "packed tight" and not just floating around or loose.
id probably have to disturb it somehow to flush it out.

If you don't want to tear into it, drain the system, pull the filter and 
wash it and see if you can flush out any sludge with the filter out. Careful 
using solvents as they may attack the O-rings. To completely drain the 
system you'll need to pull the line off. Just how much sludge are you seeing 
in there? If it is a lot you may need to just rebuild the whole unit so you 
can get it clean. If one of the hydraulics is letting down while running and 
then jumps back up, thats probably a broken spring. You have to remove the 
"head" (the end next to the battery box). You'll proably want to change the 
little nylon valve while you are in there. Those hydraulics run trouble free 
for years but when they start acting up, they can be a real pain and get 
quite expensive depending on what you have to have. The last one we opened 
up had to have the filter.
