Message: <blockquote data-quote="nobull1" data-source="post: 31557" data-attributes="member: 722">Discovered a new leak the other day and thought others might want to know what I did to remedy the problem. Here are the notes I made to myself just in case I have to do another, or heaven forbid this one again. The first ones lasted 2600 hours and are replaced with what I think are a superior replacement so they should out last me. It is a good idea to drain the hydraulic fluid first so it won't run out when you pull the spools. Lock the loader arms in the up position with the orange bar to make access over the side of the machine to the control valve.When replacing the front and back seals of the two spools in the control valve remove the front rubber covers and seals first. There are two screws that hold each cover on and are hard to get to. It is easier if you first remove the emergency release valve and a couple of the lines to the control valve. After removing the two front boots and you can remove the top valve and it will just come right out from the back with little problem and one seal attached to the spool, then sticking your finger in the front hole remove the other seal. The bottom valve will be easier to access when the top one is removed, and comes out the same way. When replacing the seal on the spools make sure you take notice of the way it goes on, with the raised bump on the OD of the seal to the inside of the control valve (which at first appears wrong). When you replace the front seal behind the boot it goes the same way bump towards the control valve. Both spools and boots should be removed at the same time and the two front seals and boots should be replaced before replacing the spools with the back seals. The spools will just slide right in and you just have to replace the two screws attaching each spool. IMPORTANT TO NOTE: Do not at anytime take the clip off of the back of the bottom spool as there are two balls and springs that will go flying if you do. You just have to take the two screws that hold the cover to the control valve off and pull the spool and cover out. Once you have the spools installed it is just a little time to reassemble and replace the fluid. When we did my machine it took about 3 hours with minimal problems except for access to the front boot bolts. Overall a pretty easy job once you know what to do and what not to do. I have been told other Bobcat machines are similar and just might have a few more things you need to remove to provide access room for the spool removal. Brian</blockquote>
