Noticed a small oil puddle on the ground in my storage yard. Right rear. Hmmm
Repair shop said earlier that the hydraulic fans were leaking. $$$$ to fix. Told them to clean the area in their cleanup booth.
Drove five hundred miles with a good grade along the trip. Pedal to the metal.
Crawl underneath to look. Pumps totally dry.
Aha, the hoses come together at the front of the rear bulkhead. Look to be aero quip type
Union area oil wet.
My previous trips were all flat ground and no load. Not this time.
Looks easy to access and fix. Anyone fixed one? Re tighten? Shorten and retorque?
Replace lines?
Be tempted to see if the hoses fitting tighten up....

Bob, I'm not exactly sure of the area where you have the leak. But, if it is any help, I had a leak at a T fitting on one of our fan motors. I don't think it was ever bad enough to cause a puddle under the coach. I took the hoses off, removed the fitting, cleaned everything, reassembled and have not had any further leaks. I have attached a photo showing the fitting.
Last fall when we were having some service done at Tennessee RV in Knoxville, one of the techs noted that our hydraulic fan motors were "leaking" oil. I took a look at them and there was some seeping, but nothing dripping. These fan motors are very expensive. I don't recall the price exactly, but over $1000 each from FT. But they can be rebuilt for much less. The reference to who can do this work is on the forum. I talked to the service writer at MOT and he said don't worry about them unless they actually drip. No drips, so I just keep an eye on the hydraulic oil level, which is a good idea anyway.

Yes I was told the motor(s) were bad. Based on the info here I decided to monitor the amount. I replaced the fuel filter parts a while ago to fix a leak on the ground.
You got it. Same area. Nothing wrong with the filter causing a leak.
Hydraulic hose leak.....Now that it was degreased you can see where its leaking at the hose connection three feet from the fans location.
Not sure if yours is the same, maybe not. But degrease the area and verify what's actually leaking.
We just had the leaking hydraulic fan motor repaired while the coach was in our local repair shop recently. I'm looking at my invoice - $117 for a seal kit, and 2 hrs labor = $337 total. No leaks since 11/30/13.
Touched the 1/4 plastic hose that runs into the fuel filter and it almost fell off in my hand. Giant fuel leak as the nose of the coach was up a hill. Motor would run for 10 seconds then stall. Hold line up to slow leak down to pressurize the fuel system for another ten second run. Took three times to turn the coach around so the tank was downhill.
Old hard plastic hose. Went to the local cummins/truck repair. $2.25 90 degree fitting with a compression collar inside to crimp the hose. Cut the end square install everything. Pressurize the system. Another leak six inches down the line. Crud.
Lucky I bought two of the fittings. Barely enough hose to reach but no leaks this time.
Five cans of gunk. Three before I started the repair to clean the engine Bay Area totally.
Saw fuel on the fuel filter. Aha. Not the motors or the lines. Stupid two dollar 16 year old plastic line.
Wonder how much fuel I have wasted for how long? Or power lost?
Hard to see the other end of the plastic line. Anyone know what and how the other end attaches. Behind the unit. Naturally.
Not very safe. Line breaks. Motor stops. Mechanic buddy rebuilt the fuel filter unit. Did not replace the line. Wanna bet the line was the leak all the time? Hmmmm
