saw mill hydraulics

we just use the corner of an aluminum snow shovel (don't know where we would find one up here ...LOL) put a cup of oil in the corner and use a propane torch to heat the under side (do this out side) the oil will heat up and if you see any bubbles or hear crackling from under the flame then you have water, pure oil will just heat up and not bubble/crackle Jim

So Jim what you are saying is my plastic snow shovels not going to cut it?

Always knew you BLUE NOSERS were a LITTLE OFF... LOL

A problem with ATF is that it absorbs/attracts moisture In a normal automatic transmission this usually is not an issue since there isn't constant air movement in and out like there is on most hydraulic systems due to cylinders moving.

So did the crackle test today Failed badly. The water in the ATF just about jumped out of the spoon Blew out all lines . Is there a certain filter that I need to install . Will any filter work?? as long as it will screw on?
Guess I am curious about filters as to why there are so many different sizes for cars.

There are hyd filters that will remove a little water.

Best thing is to drain and refill.

 

[rasorbackq]

Thought that if I got a new filter it would be the best way to get rid of any water in the filter.

You should have a drain at the lowest part of the hyd system, and if any water gets in, and not emulsified, you can turn a small valve and drain off the water.

Ones the fluid has been emulsified, you need to replace it, and clean the system. All of the surfaces will be covered.

Also, once the fluid has been emulsified, the mix will develop new compounds, not good for the hyd system.

Looking st your system, it looks like the lowest point of the hyd system is the suction hose, and that is where any free water will collect or freeze.

Rasor.. like Jj said, it's best to dump all the oil out you can, replace it with new, then add a water sorb filter, you can get a Stauff sf-6520W filter or any other with water sorb, run it for several hours then replace the filter again with another one. you can use water sorbs all the time if you want.. i think Thursday will be a GREAT day to work on it outside... should be a nice balmy 22 below.... jim

Whole system has been drains . My plan was to fill up the reservoir and let it gravity flow out to clean up the walls Not sure how much ATF can be inside the pump and 2 drive gear boxes but I did get out all I could with the air hose . Will check today at Can tire for a filter . The ATF looks just like Pepto-bismol

The next tankful may look similar.
