At 14 years and 115K miles I figured it was about time for some preventive inspection and upgrades. Thanks to Prevost's excellent Maintenance Manual and the very helpful articles posted primarily by Jon and Mango Mike, the job was easy, a little dirty but hey, the accumulated oil and grease kept it from rusting. The job was aided by the fact that I've got a nice place to work, a reasonable set of tools, a set of air/oil jacks and 1" impact wrench from Harbor Freight, and a great assistant. Thanks again to Mikes site and various posts for the tool tips. Jon's new stands would have been nice but the blocks I borrowed from Petervs worked just fine. Would recommend the project to anyone who has a decent place to work on their bus and who doesn't mind getting their hands dirty (disposable gloves and coveralls are almost a necessity).
Included in the project were removing the wheels for ease of access, a good cleaning and inspection of brakes and suspension, and the replacement of all the flexible brake hoses, brake chambers, shocks and airbags. After the work was completed it was dead simple to do a good soap bottle/ultrasonic leak check of air lines, couplings, and Norgren valves with the wheels off.
Inside the bus we removed the electric Cadet and Wabasto heaters for cleaning and inspection. The Webasto heater motors were all badly worn and have been replaced along with their respective heater hoses. In some ways this was a worse job than the heavy external stuff.
By the way, the tidy floor, daily tool pickup and numerous other nasty chores were done by Beverly who actually enjoys helping in the bus barn and who now knows the difference between a quick release valve and a leveling valve. She ain't bad behind the wheel either.
