Cummins 400ISL Engine Fill Location

I have a 2005 Monaco Dynasty with the 400 HP Cummins ISL engine. I am about to change the oil, filters, and grease the undercarriage. Does anyone know where the oil fill is located? It appears that it may be on the rear of the engine, but I'm not sure. I haven't found any other removable caps that look like oil fill caps.

Hi and welcome to the forum.

I'll move your thread to the Monaco Owners Forum but on my 2007 (Winnie) 400ISL the fill is under the rear hatch next to the dip stick.

good luck

rafferl....Just some added info. Your ISL has two drain plugs, one is just above the other. It allows you to drain some of the 24+ qts and then drain the rest. You have a couple of grease fittings on each side of the axle(s) near the brake air cans that are sometimes missed. You also have two on the u-joint where the driveshaft connects to the rear end. Either will fill the entire u-joint. There is one fitting on the slip joint of the drive shaft. When filling this one, you need to place your finger at the rear of the slip joint (between the u-joint and slip joint) where you'll feel a hole at the center of the pipe. Place your finger over the hole while filling the slip joint fitting. This will prevent the grease from pumping out the back of the slip joint. The front fittings are fairly easy to locate, but there are three on the steering column. One is obvious, (down low) one is harder to find about half way up and the third one requires that you pull the housing off of the steering column inside the coach.

Because of the torque these things produce, they recommend that the driveshaft be lubed every 5000 miles.

Don, Thanks for the information on the lube points. Where is the fill location for your cummins engine? It appears that the fill tube on the 400 hp engine in my 2005 Dynasty is on the rear side of the engine just in front of a plate stamped with the indication "TDC". This tube is about 1 1/4 inch in diameter. Is this the engine oil fill point?

Thanks for the help.

You can fill it where you mentioned on the front of the engine or you can go in your bedroom closet and remove the floor access and fill it from the valve cover top. I have done it both ways.
