AI Propane Gen Set Oil Pressure issue

We ran our generator Friday night for 3 hours w/o any issues. Saturday morning I started it and it ran for a short while before it shut itself off.
I repeated the process and got the same result. The light flashed 2 x after shutting off and the readout in the panel was 8111.5.

I can't seem to find out the significance of the 8111.5 reading but the light flashing 2 x indicates an oil pressure issue.

Our unit currently has 50 hours on it and I last had the oil change a little over a year ago when it reached 20 hours of operation.

Has anyone had a similar issue with theirs? Is there a DIY fix for me to try before I call to get it serviced?

Thanks!

Mark

Have you checked the oil level? I had no discernable oil consumption in 15 hours, but it is possible that your oil level is down, causing low oil pressure. You may find it easier to drop the spare tire to remove the access panel to check the oil.

Thanks Titus!

I did check the oil level and it was down. So I changed the oil and that took care of the low pressure indicator light!

Is there an easier way to check the oil other than dropping the tire?

I am not aware of an easier way. It might be possible to check the oil without dropping the spare, but it would be extremely difficult to add oil without dropping the spare. I have always done it at home in a paved driveway, where I can drop the spare onto a dolly and roll it out of the way. Dropping the spare also gives me the opportunity to hose it off and check its air pressure. I found that my spare was seated against some metal ridges sticking down from the frame. The ridges were gougeing into the tire, so I cut some short 2x2 blocks of wood and zip-tied them between the ridges. The spare now rides against these 2x2 blocks.

Yes - I had those same metal ridges against the spare. I think they are part of the factory spare tire carrier that Aisrstream just chopped off and left sticking into the spare tire. I also added wood blocks. Great minds think alike!

I should check mine to see if they are still doing that... at least there is a proven easy modification...

Any chance there are photos of blocks in place? Or maybe something that will become apparent when I look under...

I will e-mail you some pictures - not the best because the tire is in place, but you'll get the idea. I think the ribs (and associated imprint on the tire) will be obvious once you lower the spare. I put a 6" long 1 1/2 x 1 1/2 board between the ribs and ran zip ties through some existing holes to hold the board there when the tire is lowered. You will see that the tire sits a little lower when hitting the boards than it did when hitting the ribs. But it is still far above the bottom of the generator.

Thank you!! I am amazed that those pieces of metal did not cut into the sidewall of the spare tire!!

WACHUKO - I don't see the issue you guys are talking about. I have VB Air Rear Suspension which puts the spare/carrier at a different location than the non-VB units. I think this issue would only be on the Airstream modified spare carrier which is re-mounted closer to gen. The VB units use the standard Sprinter installed tire carrier which is way back towards rear bumper, almost at rear hitch

Good to know Alex. One less thing to worry about. I still have go down there this weekend to change the oil in the generator. So that means that I should have more space between it and the gen cover...

I did the spacers in the gen and can’t remember...duh!! let me just look at the photos I took....

My EXT has an underdeck storage box back by the hitch. It extends forward from the hitch about 15" and the spare tire is sandwiched between it and the generator. Do the later ones not have the underdeck storage? In some ads it is shown being used as a cooler - filled with ice and your favorite tailgating beverage. Bring lots of ice - it has ~ 20 ga sheet metal walls. There is a rubber drain plug at the bottom - apparently they are serious about that cooler thing.

TITUS - my 2018 does not have the underdeck storage. So my spare is butt up against the hitch, which makes it easier to remove and more room between it & gen. I still wonder to this date why they deleted this standard item. I wished that underdeck storage was still available. I was told by service folks it had to do with VB Air, as I saw the storage was still there on a 4x4 2017 (which at that time could not be ordered together with VB Air). But I do not know if that explanation is really true.

Correct... only non-VB Air had that storage.

Looks like plenty of space to work without having to remove spare... (humm, thinking outloud, I wonder if I should order one more TPMS sensor and install on the spare as well... just for kicks.. )

Mixed photos from before and after modifying generator exhaust pipe... but you can see the space available to work between gen and spare
