It's got all the signs of being the work of a disgruntled Australian, doesn't it?!
Hmmm? Now who would fit that discription?

Nobody we know. I'm sure you're thinking of Squizzy, but I assure you, I sent him to the bush a couple of weeks ago to get re-gruntled, and he's fine now, really... :yup

Hey, I'm watching you guys! It's nothing like Vegemite..it looks more like a can full of neglect to me Jeff, a filter will generally get like that if the machine is left unused for long periods.
And I got all Un-Gruntled again on the weekend. I got one of those cheapie air compressors awhile back, just for blowing out/cleaning stuff and the odd tyre...well it seized solid...broke my 16" cut off saw...and everthing else I looked at needed fixing:Banghead Spent the whole weekend working on equipment when I should have been relaxing with my family

Was it one of those "Oil-less" air compressors? It wouldn't suprise me if it was.
I'm not entirely sold on that whole idea of a compressor not needing any oil.:spaz

No, Dusty. Look at the filter, and leave Jeff's ears alone....

Can hydraulic oil get microbe growth problems like diesel fuel can?:beatsme

That's a good question, and one that I don't know the answer to, but I'll take a guess.
I'd guess that the oil itself could get growth, however, the systems are dis-similar enough that it doesn't happen.
Fuel tanks are subject to being emptied and refilled much more often, which leads to the possibility of contamination entering on any given day. We've discussed keeping the tank full overnight, because of the condensation that occurs from moisture in the air. You don't have that in hydraulic systems. They get filled, and hopefully stay filled. (And you don't see sump bowls on hydraulic systems to collect the water, do you?)
Also, hydraulic oils gets circulated through the system, and heated up when the machine is run. It doesn't take too long to run the entire capacity of the system through the filter, and the heat probably isn't too healthy for the little critters. Fuel, on the other hand, sits in the tank and only gets drained away at a couple gallons per hour, and while the warmth of the machine running may warm it up, it doesn't ever really get hot.
Those two things would, I think, discourage the start of algae growth. If it can't get started, it becomes less likely to grow to be a problem.
(At least that's what I'd guess.)
I've never heard of it either, but it might be possible.
I think water does have to be present to get the growth started, although I did have about 1 teaspoon full of water in the drain plug cavity.
I've the suspicion that the crud on the strainer element may be a hardened paste of concrete dust/fluid mix. The environment that the loader worked in had concrete dust in the air continuously, and the dust would settle on everything in the area. Some may have been able to enter the system through the tank breather after many years of being in that type of environment.
I've cleaned the tank thoroughly now, and ran a magnet through the complete interior of the tank, with no metal present on the magnet. I don't imagine concrete dust could've been good for the system, if that's what it is, but am hoping the filter did it's job and pump/valve wear isn't excessive. The hydraulics work well, and will easily build to cut-out pressure on the gauge(1500psi), even at idle. My main reason for pulling it down was the excessive pump noise cause by cavitation from lack of adequate fluid flowing through the strainer filter when the fluid was cold/thick. It's now:thumbsup with it clean, even when cold.

Jeff, Cladosporium Resinae or as my mate used to call it "Gladis Moncrieff Spider Venom" grows on a water fuel interface...not actually in the fuel. And botanically it has been re-named by some rocket scientist and I can't remember what its called now
You can read more at the fuel doctors:

I have never seen it in oil but we used to sample for "Biologicals"??
I believe you have very scientifically and accuratley done a self diagnosis of your filter...its just crud that has had significant moisture present for a long time.

filter plugging
Jeff, I can't really tell from the picture, but your description of your filter being plugged with "belly button lint', leads me to believe that the stuff is actually hydraulic cylinder packing material. I have seen this before, and it usually comes from very worn/old piston packing and/or seals. It really doesn't seem to hurt anything, other than plugging your filters, as long as your hydraulics are still working ok.

Remember, we're talking about Jeff's ancient equipment here, so who knows...:beatsme

I should've mentioned this when I made the "belly button lint" comment, regarding the filter.
Before I washed it in a can of gas the oily/fibery "belly button" stuff was on much of the filter, but was washed away by the gasoline. It likely was just what you said, old cylinder packing.:yup
The picture I posted was after that was removed.
:bouncegri This is true Joe, but you forgot the part I like best....................it's "paid for" ancient equipment.Electra_Glide said:
And as for you Mr. Squizzy, all I can say is you're a man of many hats. Which is not a bad thing.
Here's another question for you guys. One of the flexible brake lines was getting pretty bad looking due to excessive flexing in one spot. I've decided to replace it.
When I removed it, it had more course threads than I'm accustomed to seeing on a brake line, and the hose said 3/16" 2 wire. It had male threaded ends with flares, on swivels. It looks like a common hydraulic line, rather than a flexible brake line on other hydraulic brake systems I've worked on. I checked the other flexible lines and they are the same.
Is it possible it uses standard hydaulic hose for the brake sysytem?:beatsme
I assume it uses DOT3 brake fluid. It smelled like brake fluid, and had a very thin viscosity. The brake cylinder looks like a standard manuel brake cylinder found on older cars.
I've no manuals or info to go on when working on this machine........yet.
If hydaulic hose will work I'll just have the hydaulic shop make me the new hoses.

Did you choose this method becasue of your personal expeience in dealing with belly button lint? :cool2

Yep here we are again....In the Truck of Ontopicism, perched on the edge of sanity...looking for Angel Gear as we go over the side.... Ya gotta laugh
Ok you two, I'm steering this thing back on course.:yup
In my search for the brake line I learned that my line was not a common hydraulic line. Apparently brake lines have a reverse taper to the ends, which I didn't even realize when I looked at it.
The hydraulic shop took one look and knew right away it was a brake line, and that he couldn't make one since he did not have the reverse fittings.
So I learned something new, and I got one that was close from Napa, and adapted it too fit.:thumbsup
And Digger, my belly button lint problem is easily solved by putting a wire wheel in the cordless drill, and going after it with that. Whatever's left over I blow out with the air compressor.
It's tough on the belly hair though.:wink2
