Hydraulic fluid for slide leaking.

Having trouble tracking down a leak in the hydraulic fluid for slides. Have to add fluid to get slides to work on 2002 U320 every couple of uses. Carpet in bay is oily but having trouble locating where oils is coming from. Connections don't appear to be the problem. Does not take much to get slide working, couple of pumps from small oil can gets it going. Thank you in advance for your help.

Miles, I had a leak on one of the pressure switches on the equalizer ram that is overhead in the bay in the middle of the coach, crawl in on your back. Had one in the rear slide, ram. Rebuilt myself with help from seal store in Vegas. Now I have one from the pump motor that I have not tackled yet. Lay news paper or paper towels down in bay to locate. Mostly can see with bright light on your back. There are numerous places for leaks, slide locks, rams, pump, actuators, hoses, etc. It's an Easter Egg Hunt. Let us know what you find.  Jim.

Spotted some oil on motor, not sure if it was from motor or came from somewhere else. Put white paper down but that has not revealed anything. Carpet in bay is oily. If there is a leak from top of slide will it drain down to bay?  Thank you for the suggestions.

There are several places for a leak, I assume main slide.  I don't have a second slide. 

But first, when you say you are adding oil, you should be using Dexron or multipurpose ATF fluid.  Our 2002s have the train slide system.  It was a one year only thing.  You need to check the oil level and fill with the slide extended.  Most other years, the oil is checked with the slide retracted.  Before you add oil, what is the tank dip stick saying for the level?

If the oil was full after your last top off, I'm surprised that a few squirts of oil is enough to make a difference for the system, but I guess it could.

Your slide pins could be leaking.  If it is the bottom pins, you can lean in and look up to see if you find a leak.  If it is the top pins, you should probably see a leak spot on the top of the slide.  If it is leaking down into the pin receiver block hole, it should drain down and out the drain hole in the center, outside, edge on the bottom of the slide.  The hole is about 3/8" in diameter.  Something to check. If the drain line is block with dirt and debris, you can blow it out with compressed air from the bottom.  Put a rag over the receiver hole on top.  Otherwise, you can blow a lot of dirt  onto the top of your slide and the bottom of your awning.

Your sync cylinder could be leaking.  Mine is mounted to the top of the third bay (counting the generator access door) in the center channel.  Like, fourdayoff said, put down some paper towels or newspaper to show where the leak is. 

It could also be leaking near the pump.

Over the last 11 years, I've had a pin leak and a sync cylinder leak.  If it's a sync cylinder leak, get it repaired as quickly as you can.  If the mechanism gets out of sync, it can cause a lot of damage.

Appreciate the reply. Probably need to look at the top of the slide. We will keep at it.
