Haldex Air Dryer service due?

It's been some time since I last performed the service on my Haldex air dryer, and not sure why but I'm sensing it's due to be serviced again.  It shows no sign of any white powder nor water in the system when I open the relief valve in front of the rear wheels and the dash air gauges show normal readings.    Nonetheless,  I seem to have misplaced my file containing the p/n's of the kit and where I purchased it back then.  Searched best I can on  Barry's "beam-alarm" website (which BTW is an excellent info resource)  but must be looking in the wrong places, as I'm not having any luck finding the p/n of the kit I need.  Help?

I plan to have mine serviced again this fall when it hits the two year mark.

I keep a major kit in the parts box, and go through mine every 3 years. I'm thinking for replacing mine with an AD 9 Bendex, they seem to have become the go to air dryer. Easier to find parts.

Having just updated to a AD-9, it is essential you monitor the air purge outlet on the bottom for excessive oil.  If you have a doubt where your air dryer exhaust is located, just park on a gravel pad and wait for the Dryer to purge, soon you will see a area about 12" in diameter where the gravel has been moved.  Now with the engine off, wiggle under your coach with a flashlight  and look up  for excessive oil, if the area is dripping oil, it's time to service the dryer even if it's sooner than the 3 year mark.

Preparing to rebuild Dryer on our new to us coach. Wondering what advantages would be to replacing with modern Bendix unit would be if the 20 year old unit has performed so well?
