Re: Replacement nylon fan for our 8.2 DD RV
Reply #10 –
First I talked to a Josh Harnesy at Superior fan via email. He sent info request form for me to fill out.
I filled it out, emailed it back, got a reply with part #828200-24" nylon fan. Not too much later I got another email apology from Josh saying that he missed the 8.2 L DD spec and the DD 8.2L fan mount has a 2.05 pilot diameter for the fan to locate on.
New, correct part number then was #828205-24" Number of blades went from 6 to 7
Really looking forward to getting coach home from storage in a couple weeks. Have to wait for our roof replacement on the house and the storage facility to have nice firm ground.
I already have (5)5/16-18x5" lg hex head bolts with the heads cut off and opposing flats ground on what was the head end--for finger gripping. Because I will be laying on my chest on top of the engine and working by feel over the fan and inside the shroud I plan on doing the switch this way: (1) loosen but do not remove fan belts. (2)Remove a 5/16 hex head bolt with my 1/2" socket and replace the bolt with the "headless stud". Repeat five times then slide the old fan rearward, lift it up and out.
Compare everything between the two fans. Install NEW fan belts, then reverse the fan removal process with using the new fan.
Because everything has to be done by feel I want to keep the holes in all the parts in alignment.
I have (5) studs because I will probably drop one or two and it is a real pain to get out from under the bed, go outside and then fish around until I retrieve the stud, then back in & under the bed. Keeps the grease dispersal to a minimum.
