How to work on 763 valve connections

[chuckinnc]

Im new to skid steers, bought a 763 last fall & noticed while it sets it leaks all the hydraulic fluid from around the main valve. I tried lifting the cab but still cant get to the valve easily, How can I get to the valve? For one thing my lift arms are in the way & when I shut the motor off to lift the cab the arms wont lift to move them out of the way?

For the arms, you need to lift them and use the lift arm support, its the orange “thingo” attached to the right hand lift arm (think its the right). Put it in place and lower your arms still its seated. Shut the machine down then pull the red knob on the right side of the seat to release any pressure that still in there. Now your arms are locked up and will not fall on you. The only thing is your tilt section may still have pressure, I'd suggest you remove the bucket first so you don't have anything that can still create pressure as you will be working on the control block.

Thanks Tazza, Ive never done this before so as simple as it sounds I didnt think of supporting the arms first, Ive done this many on my tractors loader, my 763 dosnt have a support so I will cut a piece of angle iorn to put on one side.

Just ensure its secured at both ends, you won't want to risk them faling in your head! Even if you can also attach a chain to the arm and the shed “just in case”.

As Tazza said, be super careful and make sure the orange safety bar is secure with safety 'clips' in place. A local bobcat dealer lost 'two' mechanics, both were working on the control valve, without the safety bar, it fell killing both. I remember that story every time I work on mine. If I scared you......good.

My thoughts exactly. With the spool out of the control block, there is NOTHING to hold the oil back if something was to happen to the safety lockout. I have never had even a close call, but stuff like that scares me, so i ensure when i work under the arms if i can't put the safety bar on, that i chain the arms to a secure point.
No matter how careful you are, acciedents happen.
Let us know how you go though!
