Hi guys,

Sorry, I tried searching, but oddly enough, didn't have any luck. I couldn't even find something on youtube! I'm sure it's my lack of search skills, haha.

Anyway, I recently bought a used 5455 snowblower (with hydraulic chute rotation) and 2751 quick attach and would like to flush the old hydraulic fluid out and refill with new before I hook it up to my machine (BX25D). Could someone please point me to a thread that explains the procedure or give me a quick how to.

THANKS!

Cylinders are a bit messy but you can do it by taking the hoses off and pressurizing one end with air. The piston will move down and force fluid out the other end. Then reverse the operation to force fluid out of the other end. The hoses could be left on and used to direct the fluid into a bucket if you have a way to get the air pressure into the hose end.

if you really want to get more oil out then you would need to either install some of the preferred fluid into the cylinder ends or take the cylinder apart and drain it out.

You could naturally hook one hose to your tractor and force the piston one direction and fill that side of the cylinder with the tractor fluid while the far side is being drained into a bucket. Then switch ends and go back and forth between the ends being connected or drained until you felt good about it.

There is not that much fluid in the cylinders that would contaminate the tractor fluid but you can minimize that amount if you want to put in the effort and create some messiness.

Have fun

I bought a used rear blade with three-way hydraulics last year and wanted to get the oil out of all three cylinders. I simply removed the couplers from the ends of the six hoses and used enough compressed air to move the pistons back and forth, first one way, and then the other, while draining the oil into a container. I did this a number of times until I was satisfied that the old oil had been removed. I ended up with something like 1-1/2 gallons of oil.

I use UDT2 so had no desire to mix whatever was in the cylinders with the liquid gold in the tractor.

THANKS GUYS! Well, that sounds simple enough. It's kind of what I had in mind, but since I have no experience doing it, I though it best to ask here first. I've certainly messed things up before by just winging it and hoping for the best, haha. I'd better find the time to get this taken care of soon...snow will be here any time now.

I definitely appreciate you guys taking the time to help out :)

Don't forget to remove the shear pins and ensure they are the correct size for your snowblower. I have found many instances where the owner didn't care enough to use the correct shear pin and instead replaced it with a stronger bolt that wouldn't break when the impeller struck an immovable item. Also, warm the gearbox in front of a heater, and then drain and change the gearbox oil in both gearboxes.
