BA, here was his question..
where is the best place to source the valve on the Marathon tank.
Rick asked about the tank valve, not the compressor outlet check valve, so there.

Tom,
I like how BA can use a curved line and outline in Red what is the critical part. It’s shows the training program at NAPA had some affect on an old Gumshoe detective.

Rick,
I just ordered and received my check valves from Valve Check Inc. They were great to deal with and when I told them that I heard about them from Prevost Community, they told me that several members have recently placed orders with them. Be sure to mention that you are from Prevost Community when you order. I tryed to convince them to be an advertiser on the Prevost Community site. If you can convince them to advertise, Tom might wave your dues for next year.

outbound line on the Thomas compressor …….’ll cover both bases.
Replacing the check valve as pictured on the Granger 3 gallon green Marathon AUX air storge tank part number is ……
Manufacture by SMC # NAK4000-NO4
Ordered that check valve on e-bay or you can check any vendor selling SMC parts. Price varies… some vendors will not sell one valve only.

Finally, spending the day with the coach, and finally got the second mini airbag changed. The bolt on top of the
airbag is really hard to access. I used a quarter inch drive ratchet with a swivel extension. There is no
room to turn the bolt, but I finally figured out if I removed the nut on the bottom of the airbag and turned the
airbag itself while holding the bolt with the rachet I could remove it. The threads on the airbag are plastic, and only
keep the bag centered, so it worked. Reversed the process for the install of the new airbag. One leak down.

Changed Al’s said valve with Prevost valve…belts still loose after 24hrs…need part number for the mini-airbag engine area…
Appreciate your assistance!

Prevost# 950208, 3″ on my bus.
Or do a mechanical replacement. See this thread here on PC:

or go to the “Articles” section for the way Jon did it.

Replaced mini airbag on cooling fan belts (3) AX73, now belts are tight for up to 60-72 hours…mini airbag under engine compressor is aired up all the time…must have another leak somewhere.
Front and rear air gauges drop to “0” within 12 hrs time…
