Help with hydraulic hoses

    I have a curtis sno pro 3000(2003) and want to change the hydraulic hoses. The problem I have is that I cannot get a wrench to the hose connections at the manifold. I am blocked by the motor on one side , on the top by the float, on the other side the jack hose is attached (female connection) to a brass looking connection on the manifold. I thought I could remove the female connection for the jack hose to give me room to get a wrench on the other hoses(male connections) but the connection for the jack hose is a part of the manifold and still not enough room for a wrench. Any advice/help would really be appreciated

    thanks for the web sites but my connection is a 9/16 nut so I assume I need sae line wrenches. Also I ordered the replacement hoses from discount plow parts(mill supply) and the nut on the male end on the replacement hose is 5/8 inch. the one I'm trying to get off is 9/16 inch. Is that going to change the thread size going into the manifold? Obviously I can't check because I can't get the 9/16 inch out

    You can probably use a metric wrench to remove the old hose and install the new. There are several metric sizes that are very close to fractional, 9/16=.5625" and 14mm=.550", 5/8=.625" and 16mm=.630". Between the tolerances on the nut and the wrench you should be able to use a 14mm and 16mm wrench to remove/install the 9/16 and 5/8 nut.

    Here's a link to a conversion chart http://www.highlandlighting.com/conversion.htm
