Icy Hydraulics

Post by fundytides » Sat Dec 08, 2018 7:27 am

My 40c has been outdoors for a few months while I used my heated space for other projects. Finally went to move it inside a few days ago and the blade wouldn't lift. I jacked up the blade, chained it in place and moved the crawler inside. Tried it yesterday and hydraulics were back to normal. Probably ice somewhere in the system but where would the water come from? Condensation? Do I just change the fluid and carry on or is there something special I should do to make sure there is no water left in the system?
have 40c 4 roller crawler, 1927 Ford T Touring car, 1931 Ford A Roadster, 1951 Standard Vanguard Saloon. Never a dull moment!

Change the fluid, which will help, but you don't get all of it out. From what I have found, Seafoam can be used in hyd systems to reduce or help with moisture. You need to get the hyd oil hot which is hard to do.
