753 Bobcat

Hi all I am changing control valve seals and everything was going fine until I removed the spools and the book says I have to remove the valve in order to install the quad seals, I watched a lot of videos showing how easy it was to do with the fanged seals. Has anyone been able to get the quads installed into a valve body without a taper without removing the valve??

I've got a 753 F series. I removed the control valve a couple of years back. The exercise is a lot easier with the valve on a table. The hardest thing I found doing was getting the hydraulic pipes lined up and making sure not to cross thread them.

Hi all
I have a 753G series and am having trouble lifting the operator cabin.
I have removed the two nuts on the front (and washers) and the cabin moves a little bit but is being caught or stuck on something?
The manual I have doesn't have anything else that I need to do but I can't lift it up. Any ideas ?
Thanks operator

It should open if the two bolts are removed.

You need to look for anything that could be interfering with it first. Check to make sure there is no debris behind the cab or in the hinges, check that the throttle and levers are not catching. I had a 742B that the throttle lever would get in the way of the cab opening and closing. You may want to have a helper while one of you tries to open it the other checks for catch points.

Also, there are springs that assist in lifting the cab. If any one of them is bad you will have to use a jack or crane to lift it.

It lifts up a couple of inches with those nuts out but then gets caught.
It's a definite hard stop like something is blocking it. Is there anything on the seat or behind it?
Springs feel ok and have no signs of leaks. Positive they woRk as I can feel it catching

There shouldn't be anything in the way preventing it from going up. Perhaps one of the strong arms on each side of the machine is bent? Sometimes it helps to get a pry bar under the front to give it an extra boost. Once you get it up, make sure to prop it up with something other than just the locking mechanism. I like to put a steel bar on top of the lift arms across the width of the machine and under the cage so there is no possible way for it to come crashing down.

I will do that and try again, thanks

I had to use 2 2x4 screwed together to give me leverage.

Perseverance and clearing the seat bolts did the trick - thanks heaps

The RHS steer handle bar arrived today which is perfect timing to replace
