Service Checklist for a 2006 Monaco Knight 38PDQ DP

[Bronccat]

Our 2006 Monaco Knight 38PDQ has the Cummins ISC-330

I am planning on doing everything myself and I am operating under the assumption that everything is due.

Is there a check list for servicing a DP? So far here's what I think I know:

Change the oil (TBD) and filter (Fleetgard LF9009)
Install a Fumoto drain plug valve (maybe)
Change the fuel filter (FF5488)
Grease fittings (is there a diagram anywhere?)
Air dryer cartridge (system saver 1200 (picture in manual) R950011 filter - does brand matter?)
Coolant filter (gotta look for P/N)
Service the Generator (oil, filter, fuel filter)

Thanks!

Depending on the chassis there is generally a maintenance schedule. Also need to check oil in front hubs. I don't think they have a coolant filter. I never had a DP with one but my 6.0 Ford had it.

Do you have all the manuals for your coach. I bought my coach used but it came with all the manual including the Roadmaster Chassis manual which had the lubrication maintenance required with a chart showing how often and what to use as per the lubricant. It also came with a nice diagram of the grease points.

The operator manual also has a complete parts lists towards the end that has all the filters plus a list of recommended spare parts. You can download an electronic copy of your manual here.

You can also request a complete set of electrical schematics here
Contact Monaco Coach

Fill out the center column with VIN, while your at it request a copy of your data sheet which has all the main components listed by manufacturer and Model # and sometimes SN.

I would advise that you find your nearest Thomas Built Bus dealer
and take your coach to them for a complete evaluation and full
service on all systems. Your chassis is familiar to them since you
are likely the same as a school bus. Don't know your
chassis, but, for example,on a Freightliner, there are 42 specific
grease points ! They will also have a full maintenance schedule for
everything on your coach. In my opinion, if they do not have
the equipment to lift your coach to have full access, then find
another shop that does.

Also, this is the first of six youtube videos that show a very thorough pretrip inspection. You can find the rest at Static Nomadic's youtube channel.

Monaco use to sell a 3/8" thick, by 8.5" x 11" book that contained all the lube points, oil and grease info for the Roadmaster chassis. You might call Monaco and see if they still offer it through their parts department.

Thanks all, great information here.

I am fortunate to have purchased a one owner coach and I need to dig a bit deeper into the docs I have and perhaps try to get the most recent service records.
