Default Hydraulic system leak

Starting to prep camper for an initial short trip in two weeks. All is good except the hydraulic reservoir is empty with a brown dead grass spot underneath the compartment. Did not have time this weekend to tackle it. Any advice would be helpful in tackling this issue.

Sounds as though your reservoir has a crack in it, or a leak at a fitting. Clean the area under it very well then put some Dextron type IV in it and see where it leaking. Sorry, don't know where to get a new reservoir. I doubt this loss of fluid is from the cylinder, but check the plastic tube from the reservoir to the cylinder, hopefully, there will be little or no fluid in that line.

We need to know where the leak is. Is the fluid on the ground under the pump area, between the pump and the hyd cylinder, or under the hyd cylinder? It would be unusual for the reservoir to crack. The pressure line from the pump to the hyd cylinder is usually steel and do rust thru with age. Look there, it is easy to replace. Could be a seal in the hyd cylinder. It can be rebuilt, a bit of a job to remove. As treeclimber said check for loose fittings and the plastic vent line. Try putting fluid back into the reservoir. If the top is up put aprox 1 or 2 inches in the bottom of the reservoir and if the top is down fill to 1 inch below the fill opening. Recycle the pump to bleed the air out of the line and if the fluid level goes down keep adding fluid until the air is out and the top will raise OK. This will help locate the leak and you may find that the leak is so small that you can go on your trip and fix any leak later. Try these things and let us know what you find. It would be very rare for the pump to leak. Use any Dextron fluid up to Dextron 5 but do not use Dextron 6.

Thanks to both responses. The dead grass is directly below the pump compartment. I may be able to look at it tonight after work. Thanks also for the Dextron VI warning. I just bought 3 quarts but did not have time yesterday to work on this issue.

Jim, not 100% sure but I think the tube back to the reservoir has a check valve at the tank preventing fluid from the reservoir to the tube. Otherwise, the tube would always be filled with fluid. Basically, if the cylinder has an internal leak it sends the fluid to the reservoir. If all is well, there should be NO fluid in that tube. Your right about a cylinder removal, not fun.

PS: where would one get a reservoir?

Oils have a funny way of moving around and away from the actual source, sometimes making it hard to find the leak.

An old shade-tree mechanic trick is to really clean everything (spray some degreaser on and then rinse), let it dry, then toss some baby powder/corn starch on the areas where you think the leak is coming from. A leak will create a path through the baby powder that you can trace back to the source.

I’ve done this on motorcycle engines where air flow just blows the oil all over, and it really helps.

Tree, JR MIGHT have the reservoirs. But, I think cracks could be repaired.

If repairs are needed, I'd certainly take the reservoir out so that I could clean the repair area thoroughly. And, if there was a crack, I'd stop drill the ends before applying any repair material.

Knotty, in Naval aviation, we chased hyd leaks all the time. Your right, they can be tough to find. Lint free rags to the rescue. Hopefully, Raguillard won't have too much trouble and it will be a simple repair. Just for my own info, I'm gonna check with JR and see if they have a reservoir.

Thanks for all the good advice. Will not get to look at camper until this weekend. But will certainly put all your advice in play. I do remember that there is no fluid in the plastic line. The grass is dead only under the compartment with the pump and batteries.

My father was a mech/flight engineer in the AF for 20 years...heard some great stories of how much planes actually leak (if most civilians had *any* idea...) and things don’t work (oh how he cursed the C5’s new “hi tech” systems that never worked right). Learned a lot from him (like the corn starch).
