Started doing Break in maintenance on New Aire

Yesterday tried to remove the top engine hatch in the bedroom. I thought it would be easy access to fan gearbox. Not so, removing bottom hatch not reccomended as it requires far more then just lifting it out, far more. So I avoided that and removed air cleaner and piping to get access.
By climbing in on top of motor after removing piping, I found total and complete access to the engine upper area for all required maintenance and good access to the fan gearbox. I see no need to use that hatch for anything going forward.
Just as the factory techs told me my fan gear box needed an early oil change. The magnetic plug had plenty of break in metal attached and the oil was metalic in reflection. Typical of break in activity but itís also good to get it out of the gearbox for extending oil seal life. I just used the reccomended Delvac oil for flush before refill. I see why early change/flush at 6 months is reccomended in service schedule.

Mine was changed from below. Required 2 man hours to pull down panels below the gearbox. Not happy with any design that makes so much metal during break-in. Suggests lack of proper machining.

Removing the intake system may provide access but at a higher risk od "dusting" your engine.

I disagree, opening and visual inspection of air filter Assembly and hoses are important and prudent procedures required at least annually as per service schedule posted by Freightliner.

I also disagree. Inspecting and cleaning the air filter will extend it's life and possibly the engines. I want to know what's going on.
