Onan 7500 Diesel Generator

I have a cooling fan that needs to be replaced. I have removed the older broken one by removing the top cover of the gen set. The problem comes in reinstalling the new one which actually has all the fins on it as now there is not enough clearance to come from the top. I removed the wire cage on the bottom but there is a slight interference with the radiator shroud that will not allow it to fit that way. Has anyone replaced this fan on the 7500 Onan Diesel Generator that can tell me short of taking all the panels off and removing radiator or shrouds of how to get the new cooling fan into place ? Any suggestions will help.

    I bought my Onan in Ashland. Nice people and gave me a great deal. Ask for Veterans discount if you are one.

    I did find out to change this cooling fan. Not easy but didn't want to take a lot of things loose I didn't have too. Thanks to McGeorge RV/Camping World the service guys were really helpful and even steered me to another RV place in Ashland, VA that was the Onan go to guys. They got them on the phone and discussed it with them and let me talk to them also. They guys were at Kaeser's RV Service and they luckily had one sitting on their bench they were working on. They knew exactly what I was looking at and I even went by their place in Ashland and their mechanics told me what I had to remove and also what to watch out for when I did get it apart. So helpful both shops and would recommend them as since I was doing my own work they really didn't have to help as it was taking money out of their pocket. I am grateful for their input.
