2005 Newmar Northern Star & HWH Leveling system

[Charlie and Martha]

Our jacks settle down (no oil leaking) and we come off level quite a bit. Sometimes no problems at all, other times it comes off level in a few hours. Also, the jacks sometimes are slow to come back up even when wiped clean prior to retracting them.

On my coach the leveling reservoir and controls are located in generator compartment up front behind the passenger side head light and near the fire wall.

With Jacks deployed the reservoir sounds empty when tapping on it ). I know I need to retract the jacks before I check the level of the hydraulic fluid. There appears to be a large cap/bolt on top of the reservoir and I assume that this is where I would check/fill the reservoir if required.

I have googled within the Newmar forum for information on how to do this correctly but have found nothing specific to my system. I didn't inherit the manual for this piece of equipment when I bought the coach used.

Can someone tell me the correct procedure for doing this please?

Charlie with all your jacks retracted you remove the silver Bell vent and the shaft should have two lines inscribed on it to show correct level of your fluid in your tank.
If you do not see the fluid level between lines you need to add oil, HWH is clear oil or you maybe using transmission oil that's red and easier to see.
Sound like its a fluid problem, may sound like pump straining putting down jacks with not right fluid level.
Make sure all the solenoids T handles are tight.

Thanks,

I was pretty sure the elongated nut was the vent but not totally. In my case the bell vent is black with road dust. It needs a good cleaning before I attempt to check it. Does it matter what kind of transmission fluid I use? Thanks for the information. I really appreciated it.

You can use either HWH or any trans oil should not matter, when you remove the bell may just spin and not unscrew thread portion of bell vent, may need thin pliers to grip and turn thread pipe portion of vent, to remove whole vent.
