Looks good, i wonder how much air flow it will have cut down on, hopefully it will still have more than enough to keep cool.
Alrighty. I got the hydrostatic pump out yesterday. Not too much drama. Hardest part was getting to the 15/16" bolt on the underside of the pump. I had to cut a wrench in half to get 1/8 turns. First I removed the large mounting bracket at the back of the pump which gives you great access to hoses. That also gives you the ability to jack the rear of the pump up.
Next I removed the servo assembly on the left side for access to the two large hoses on that side. You disconnect the three linkage points and two small hoses. All the adjustments should still be good.
The two large hoses have elbow fittings that can be removed after pulling the pump.
There's a T fitting on the other side that can be a little tricky getting lose because of large hoses going to the front hydraulic pumps. Note that 15/16" and 1" stubby wrenches are really needed for this job. Some hose connections quite tight and requiring a cheater pipe.
To get to that lower attaching bolt I first used a pry bar to lift the pump but then came up with this come-along rig. That worked quite nicely and left the underside clear for loosening. Your basically just feeling your way around the front of the pump. Prepare to put your face right in there unless you have really long arms!
Here's what you see when the hydrostatic pump is out. That's the rear of the hydraulic pumps. They're splinded together with an internal coupler. There's a large sealing o-ring. You see I've already sealed and covered loose hose ends with this machine sitting outdoors. After the photo was taken, I covered the exposed area with a shop towel, plastic sheet and e-taped tight.
Here's the hydrostatic pump on my tailgate. The linkage bracket was removed along with the large elbows (those have o-rings also). I couldn't get the extension pipe off so it's going with the pump to the re-builder. I doubled wrapped and taped the pump for shipping. That won't be cheap. That sucker is HEAVY!
