You need a complete new fan assembly.

By fan assembly do you mean just these parts here, or is there something beyond this?

Thats it.

I am just wondering about something. The fan hub on mine and in the pic is metal. It may be an illusion but the fan hub in the video you posted looks like plastic. Is that true?

I think it is metal it has just been filed down/expanded in the middle so it looks more soft than it is. Here is a close up of the other side of the assembly.

I do wonder if the fan assembly has ruined the tapered part of the motor though. I don't know how I would check that without getting the assembly off though.

I also wonder if I can find the parts somewhere else cheaper. Newell is quoting me 600 for just the fan assembly. Most other radiator fan assemblies are 2-300 online.

The best way I have found to remove a fan hub is with an impact gun. In your situation, it might be tough without removing the radiator to do that. Only option I can think of is the tite reach, if it will fit in there but you may risk damaging the radiator core if you are not careful.

The tite reach I use is the 1/2" professional, its designed to be used with an impact. I use my 3/4" drive Milwaukee impact on it all the time and have yet to break it.

I just went out and looked at my coach, and you could also potentially unbolt the entire fan steel support structure. Looks like to me it has two bolts in the top and 2 in the bottom. Then you might be able to move the whole fan assembly where you can get an impact in there to remove the nut on the fan hub. If you remove the hydraulic lines, you may be able to pull the whole assembly out. Just have some plugs ready as Richard mentioned you do not want to empty your whole hydraulic system.

Hmmm a lot of good thoughts.

As far as the hydraulic system goes... I already had that happen once. Within the first 5 miles of buying the coach, one of the high pressure lines split and sprayed all of the transmission fluid from the system all over the engine bay. I was smoking like I had a fire and pulled over to find a very small hole in one of the lines. Needless to say, I had to replace all of the fluid and patch the line.

So far, I have had a few pretty rough breaks in my trip to just get the coach home to be registered and titled. I am only about half way home right now and it has been 3 weeks.

I am going to try the impact wrench method to get it off. That seems like the best thing to try.

Should I just go ahead and spend the 600+ to get the replacement fan blades?

Separate question... do you know if these coaches come with an air line for air tools?

there should be an airline in the passenger side engine bay

Mine has a port right near the engine batteries, just as you open the passenger side engine access its down in the lower rear corner.

I doubt the shaft is damaged beyond repair. It is hardened steel, and the fan hub is cast aluminum.

There is a half moon key way in the OHLA shaft to keep the fan hub from spinning. It probably long gone in your situation but make sure when you replace the hub you use a key.

I’m not sure I understand what you mean by a key. Do you mean a notch where it connects with a notch on the fan assembly?
