JohnC3 Posted September 17, 2021 Share Posted September 17, 2021 Hello Everyone, On my Class A (2008 Monaco Camelot 36PDQ) my Air dryer has developed leaks 4 times in less than a year. The 1st OEM (Wabco 006110500 1200 System Saver Air Dryer, Formerly Meritor R955205) started leaking from the regeneration valve in 01/21. We replaced the complete unit with one from amazon. It lasted 4 months and started leaking from the purge valve. We got a free replacement from Amazon and installed the replacement, That lasted about 6 weeks and started leaking from a pin in front of the front air hose. We then got a refund from Amazon and got Wabco OEM. That started leaking after 3 weeks before it started leaking from the regen valve. I replaced all of these myself. These units are located about 2 ft from the engine on a separate mounting pillar. I understand that some units had issues with hoses overheating (some were mounted close to the engine and the hoses were 2-3 ft long). I don't believe mine is that type as it is about 7 ft long (Leaves the dryer travels back around a pillar and connects to what I assume is the compressor.) I replaced all 3 units myself, and am wondering if I missed something in my unfamiliarity with air systems. I unbolted the old units cleaned the threads on the fittings with threads and teflon tape on the fittings. Any thoughts? and Thanks for any help you can give.

Ivylog Posted September 17, 2021 Share Posted September 17, 2021 Well, the good news is , yours is easy to get to…. mine is next to the transmission. Doesn’t sound like you’re doing anything wrong with the installation. Link to comment Share on other sites More sharing options...
Bob Jones Posted September 17, 2021 Share Posted September 17, 2021 Just a thought, and maybe off-base, but can you replace the entire unit with a different brand/design that does the same thing? My guess is the lines are probably a standard size. Link to comment Share on other sites More sharing options...
96 EVO Posted September 18, 2021 Share Posted September 18, 2021 John, I'm pretty sure I replied to your thread on IRV2 with my experience so I won't bother repeating it. Your dryer is mounted in the same location as mine, and while it's great for servicing, I still think it's mounted higher than it should be! The manufacturer recommends a downhill slope on the feed line from the compressor. whether that could be causing us issues, I really don't know.

Fonman Posted September 18, 2021 Share Posted September 18, 2021 Dunno if this could have any bearing on the first couple, but In general my preference is thread sealer vs teflon tape. Little shreds can let go and get stuck in valves causing leaks. 1 Link to comment Share on other sites More sharing options...
