Slide hydraulic leak
I was checking my battery in the front of my 3400 and I noticed hydraulic oil on the battery cover. I check my battery regularly and this is the first time I have seen this. I looked up at my tank and it is right at the line - with all slides open. The tray under the pump, though, had quite a bit of hydraulic oil in it and this is what was leaking down onto the battery cover.
I can see a drop of oil hanging from the back of my selector block. I tried to reach back and tighten all the hoses coming into the block and I couldn't budge them. All tight.
The dealership and I have been working on our kitchen slide over the last several weeks, so the selector knobs have been busy lately. I cannot see any continuous leak - probably have to run the kitchen slide in and out to see what's going on???
Any experience/advice?

You have been up early...
I would clean them real good, make everything squeaky clean, then activate one at a time and check for leaks, maybe in and out two or three times each slide. I know you would feel better if one were loose.
Good luck.

Ours has leaked since new. Been in the shop twice and I don't think it is fixed yet.(just picked it up last evening) IIRC, I believe from prior discussions the leaks can usually be attributed to a seal between the pump and reservoir. The leak on our unit is not bad. If they hadn't run those metal screws through the drip pan, a little kitty litter would suffice. I thought about just cleaning and sealing the screws and going ahead with the absorbent.

Mine leaks from the reservoir and pump connection. After getting it all cleaned up I find that a paper shop towel jammed in by the bottom of the pump/reservoir keeps it clean. I change the towel about every 10 days. It is damp but not sopping wet. The hydraulic slide system is on my list of what not to have on our next trailer in a few years.

Mine leaks off and on, without any particular pattern. I put two magic marker lines on the tank, one each to note where the fluid level is when the slides are out and in.

May I ask what parts of our units are made by old fashion craftsmen? Seems there is a lot of bragging about that.

We have at times a small amount of fluid that will appear on the top of the reservoir or on the shelf below the reservoir.We keep a paper towel folded under both places and it may be dry for weeks then perhaps a small amount of fluid will appear.Have never been able to find a leak of any kind and have no idea what might be the cause. We do use the selector knobs a lot as we keep the camper in the driveway and at times do not want all the slides out. I think it has something to do with using the selector knobs a lot but have no idea what???

My tank was leaking real bad so I removed the tank to replaced the o-ring, but I had no luck finding a new one, so I used a little waxed dental floss 5 or 6 wraps around the pump wh ere the o-ring goes and put the o-ring back on and on more leak.

Regarding the fluid leak from the selector valves. There is a brass fitting that screws into the valve body that the shaft for the knob comes out of. I don't know for sure but I would guess that there is valve stem packing of some sort behind the brass plug. If that is true, you should be able to slightly tighten the plug and stop the leak. It's much like an old time water valve that would leak around the valve stem. You could tighten it and stop the leak. If you tightened it too tight, it would seize the shaft and you couldn't turn the valve. I believe that assembly we have in our Montanas is supplied by Lippert. You could call them and verify if tightening that nut should be able to stop the leak.

Thanks for the tip, Hawkeye. Dave, I will check that fitting, but the leak seems to be coming off the back of the block somewhere. All tight there. It would really be nice if this was in an easier position to work on. Trying to hold a flashlight and work up and around the mechanisms in the front compartment with my two bad shoulders is not my idea of fun. Almost as much fun as laying underneath the Montana, dropping panels... almost.

What do you want to drop the panels for? Hang on to them, you might hurt yourself.
