Hydraulic Leak and Air Leak - 390BH
Well, We are on our 2nd outing in the RV and I just keep learning! Today I left Kissimme KOA and the RV was bouncing like no body's business and I just learned (through this forum) I did not let the air bags inflate! I actually think it was the jacks because I pulled into Target and retracted them again and all was well. Lesson learned: Just make it a habbit to retract-all TWICE!
Now - We just got to Ft Wilderness at Disney and I have two issues I really need help with:
1. I have hydraulic fluid leaking. I saw it under the door where the pump/reservoir are so I opened the door and I had fluid in the tray under the pump/reservoir. I do not see any fluid on the lines, but I see some fluid where the reservoir is bolted to the block. I read somewhere that a lippert pump is known to have o-ring issues but to be honest I have no idea if mine is a lippert or not. I was thinking of removing the reservoir but how on earth would you do that and not spill the fluid everywhere since it is mounted horizontally? Do you have to somehow suction the fluid out before doing it? Do the slides need to be in/out when doing it? I was hoping I could take it off and clean the face (I've read that gunk can cause the seal to break) and put it back. Any advice here?
2. I have an air leak somewhere. Here is what I notice. When the parking brake is engaged the rig is nice and quiet and pressure builds to 125ish. With the parking brake off, wheels blocked, trans in neutral.. I hear a loud rushing sound near the rear of the rig and the air pressure won't rise above 75 on 1 or 2. If the tank is over 75 it will bleed down to 75 too. Also, when I press (and hold) the brake while at a stop light my air pressure keeps falling and I hear a hissing at what seems like the front. These two may be totally different issues but I could use some guidance on how to diagnose the problem. I started trying to figure out the issue because of the gauge leaking down while at a red light. Today I was backing into our spot and after a few brake uses my air alarm came on.
Our last trip we put 5,000 miles on the RV (our maiden voyage) and this trip we are going to do ~2,000. I'm very comfortable driving now, but am learning how little I know about these rigs as i encounter these issues.
Thanks for any help you guys can provide. Love this forum and I find myself searching on here all the time!
