Flushing out 54 Major hydraulics

[David Lewis]

The hydraulic oil in my 54 Major looks like melted coffee ice cream - there's a lot of moisture in it from condensation over the years. I can easily drain and fill it, but I'd like to flush the system through to clean it, and then refill and add some Sea Foam to keep it clean. What should I use to flush out the system that won't hurt it? Kerosene? Diesel? Your help appreciated.

i got mad at my major and pulled the pto shaft and used a pressure washer and clean most of the trash out, i had the front end 2 feet off ground when i did this so the water would drain out, i also use so strong soap while i was at it, It help but not that much, this year i had to pull the lift housing off for pump repairs and i could really get into the corners and got 95% of the junk out. The oil looks good now. i used diesel 2 times before i used hot water.

Diesel will kill the seals (killed the seals in my MF 135)

Kerosene seems to be what to use
