Air Bags / Air Tanks

At the Entegra U class, the Spartan presenter indicated that the lanyards for the air tanks should be pulled and checked twice a year, which is not something we have done at all. So, when we were on concrete, we pulled the lanyards in the order prescribed. When pulling the silver lanyard, which is for the wet tank, the rear and front air gauges on the dash were supposed to show little to no change in pressure. Alas, the rear gauge went to zero. No water was evident on the concrete. I climbed underneath and the silver lanyard is, indeed, connected to the wet tank located in the middle of the chassis. The other two lanyards (green and red) are connected to the two tanks under the driver and passenger seats.

Since we performed this test, the rear air gauge consistently reads zero after we have been sitting for a day or so. We are able to get to ride height and have had no problems when driving and the gauges are normal while driving. I called Spartan and they said that it could be a faulty check valve.

Am wondering whether anyone else has had an issue similar to this and, if so, whether a check valve was, indeed, the problem. Not sure why the check valve would have gone bad when just pulling on the lanyard.

Thanks in advance for any information!

When that happened did you continue thru the process of pulling the other lanyards? Was there pressure in those tanks when you pulled them? Can repeat that test again after a full air up and see if behavior repeats.

My notes from Spartan Academy:

Drain Air Tanks

Pull lanyards in RF wheel well in this order: (hold open until completely down)

1 Silver - wet tank
Check that neither gauge is down

2 Green - primary tank (rear brakes)
Check that rear has gone to zero and front still pressurized

3 Red - secondary tank (front brakes and accessories)
Both gauges should now be zero, (if not may be a sender or gauge problem)

Anything bigger than a 3Ē diameter puddle on concrete is too much water and requires maintenance, but probably safe to drive to shop.

Sounds to me like you have two problems. 1. Check valve leaking causing original problem. 2. Check valve still leaking, but in addition now wet tank manual purge valve leaking that you unseated when pulling lanyard.

RBR - Yes, we pulled the remaining lanyards and all three tanks emptied without any water.

JH - Since I agreed with your logic, I checked the manual purge valve on the wet tank and it could not be pushed shut any farther. Also, I sprayed the purge valve with soapy water when the tank was full and no signs of leakage.

Appreciate the replies!

I think you have a check valve that are bad. The one between wet tank and the rear tank.

Since you said the rear tank goes down quickly it means you have a leak somewhere in the air system.

The next question is where is the leak in the rear tank. Since the wet tank if feeding the rear tank as the rear tank uses air it is being refilled by the wet tank. So when the rear tank is empty then the wet tank will be empty also.

My first suggestion is to replace check valve between wet and rear tank. Then air up system and start looking for where the other leaks are.

I drain my tanks all the time. Prevents the possibility of corrosion in tanks that will lead to very expensive repairs. I know first hand.

X 's 2 !! and service your air dryer as needed..keep that air flow dry...You DO NOT want any dessicant into your air system...(drained water will look "milky") will coat every blamed valve, sensor, solenoids and everything else..royal Bugger-All to get everything cleaned...

Thanks for all the replies! Is it wise to replace these check valves on your own? Has anyone done it? Getting under there, it looks like major surgery.

Thanks!
Bill

Not being a certified mechanic I would not work on that stuff except in an emergency. That system is too critical for safety for my ability. Ask Spartan for their recommended shop in your area.
