Water in hyd. system I H I 35s mini trackhoe

There is no simple solution to this problem. How I eliminate moisture for my clients is to first flush the system with Schaeffer's 113 VarniClean. This will clean out any foam collected on interior walls, oxidation and any other contaminates. VarniClean is an in-service flush. You replace 10%-20% of the fluid and work the unit. This helps reduce down time. Second, you have to remove as much of the fluid as possible. Which means you detach hoses and drain them. It's a pain in the butt, however, saves you lots of problems down the road. And last, replace the fluid that has zero (0) foam tendency. Most fluids will report "pass" on the ASTM D892 test. That doesn't mean they don't foam, just not bad enough to fail the test. Having 0's in all 3 sequences of the test, proves no emlusfication occurs. This will allow any remaining moisture to evaporate safely. I recommend Schaeffer's 112 HTC Oil in the appropriate viscosity grade. PM me if you want tech data sheets and I can help get the fluids you need.

Thank You for your time and expertise. This is what I was expecting. It's about time for a complete servicing so I will bite the bullet. I went to the Schaffers web site.

Into every life a little rain must fall, Thanks for the info.

Hi Leonard, thinking you have the one machine another way of controlling this would be to use a polishing kidney filter system that you could mount permanently on the machine and as you operate the machine would remove the contamination, the best system for this would a towel roll type filter where the fluid is pumped through the end of the roll and particles are removed by agglomeration and the cellulose media will absorb the water, as this type of filter becomes loaded with water the media shrinks and you replace the paper towel roll when the pressure drops on the filter housing indicating the filter roll media is full of water.
Before you mounted the filter I think it would be sensible to test the fluid checking viscosity is correct and check the particle count which should be < ISO 16/13 on a small machine running a 2000 PSI, Breather filters for the reservoir most likely should be replaced at least every 3 months or less in dusty operating conditions,
