Newell Coach Air System Leaks: Installing New Compressor Governor

What happens here

Align the new governor with the mounting holes on the engine block. Thread in the two mounting bolts by hand to ensure they start correctly and avoid cross-threading. Once the bolts are seated, use a wrench to tighten them. The creator notes he will look up the specific torque specifications later. Reconnect all air lines to their corresponding new compression fittings on the governor. Once fully installed, start the RV engine and allow the air system to build pressure. Monitor the supply and brake air pressure gauges on the dashboard. The goal is for both gauges to reach and maintain the appropriate pressure (around 120-125 PSI) at regular idle, indicating the governor is functioning correctly.

Goal: Install the new air compressor governor and verify proper air pressure build-up and maintenance.

Tools and materials

  • Air Pressure Gauges — Monitoring air system pressure
  • Wrench — Tightening mounting bolts and air line fittings

it's good to go and this gasket looks to be the same from every direction so let's check for that got that on there as i thread this in with my fingers when i have tools but i don't use them as much as i should at least i throw it in with my fingers to a certain point because i got a ratchet wrench sitting here and you know if you're using a ratchet wrench that's too far out then the head keeps sliding off you better having a socket in that scenario but i'm gonna look up the torque spec for these right now it's just seated so we're good on that well i went looking for more compression fittings and i was not aware how freaking hard those would be to find why i don't know like advanced didn't have them o'reilly's didn't have him pat boys didn't have him like the heck bro am i gonna have to go to a back to fleet pride on monday to get this stuff like why don't this is a pretty common thing i thought i guess not i don't know it started pouring down rain and thunder and lightning and you know i don't really care if i get wet but i'm not going to stand out there next to a big aluminum motorhome and uh potentially get struck by lightning i think i'm gonna go to the gym because you know that's about it let's wait it out oh and another thing there is still a tiny dribble that comes through that skylight now when it rains so when it rains i have to leave the cover open or it will drip onto that and saturate the roof which is not good um i can tell it's already done that before to somebody else but i'm not letting that get any worse so i open that up and i put down the cover of my stove as a little drip tray so we're really doing it here you know old news stuff it's just part of the deal so i went to the gym eventually stopped raining and i was able to find a like a non-chain small kind of truck stop that was open that had these fittings so i got a handful of them and i'm gonna put new ones on here because you don't that's like the main air source i don't want to reuse a fitting on that of all things so let me get that on there then we can fire it up and see if it builds pressure and holds it better than the other one i'm really hopeful that this helps because before the whole coach would kind of lean through the driver's side if it was not on high idle and sitting for a while because regular idle speed would not maintain um 120 or 130 psi whatever it's supposed to be to like hold the back up and i read on the the new guru forum that it's like 120 125 some somewhere…
