Flushing a TPH backhoe

[psj12]

I have a three point hitch Chinese LW7 BH that was used on a Chinese tractor and used the remotes and standard 10W hydraulic fluid the transmission used 90W. I have purchased a Kioti tractor that uses the tractor transmission/hydraulic oil. Is there a simple way to flush the 10 W hydraulic fluid from the BH without contaminating the new tractor transmission?

You can either use your tractor fluid to flush the old fluid or remove the hoses and let them drain, and remove the hoses from the cyl and move the cyl rod to pus out any fluid in the cyl.

Then re-install all hoses and operate the cyl about 10 times to fill and expel any air.

Maybe hooking up an air compressor to the pressure inlet on the BH will let you cycle the cylinders and expell the oil. Put the return line into a bucket. Should work for some of the cylinders anyway.

I like the air pressure idea!
