Heat/Fume extractor blower.
Cleaning out my Generator bay and noticed a round hole in the side of the box. I saw it was a squirrel cage blower. I opened the evaporator bay door and saw this little blower back behind the cord reel. The blower is locked up and extremely dirty. I deal with these kinds of fans a lot in my HVAC business. It looks like a little Dayton 110V blower that is sold by WW Grainger. Problem is this, it looks like it could be bolted or screwed to the bay wall. It has a flexible duct running off of it through the coach floor. If that is the case the sound material covers the bolts or screws and if I touch it it will fall to dust. Also the blower will not come out with removing the cord reel. The reel looks like it may be caulked down to the floor and screwed and bolted in other areas. Any advise dealing with the sound materials and the cord reel before I just tear into it would be apprecieated.
P.S.
I have read all the threads on here about this blower but no mention of the cord reel or having to remove the sound materals. -

Steve, that blower is important because it evacuates and fumes that might collect in the generator box.
I cannot address the issue with access for removal and replacement except to say I have not yet encountered anything on any of the Liberty coaches I have owned that could not be removed and replaced without first doing some serious disassembly. That is not to say it can’t happen, such as access to the batteries is a challenge to say the least.
The insulation in the generator box has been known to disintegrate, but there are some good replacements on the market. It is a multi layer designed for sound suppression. You may be able to limit damage or when you get into the project you may just decide to replace it all. I believe there have been some posts relating to that.

Mine is tango uniform also. I ordered another blower fan unit, pt# 1TDR3 from ebay for $75 today. My difficulty getting the bad unit out was caused by the OTR evapartor fan/motor unit being 1/4″ too close. So I unbolted the fan/motor unit from the floor and moved it over a little and removed the bad blower fan unit. The insulation/sound proofing material in my genny bay is falling apart too. Its also dirty beyond belief.
I plan to kill 3 birds w/1 stone.
1) Remove the genny from its bay so as to re-insulate/soundproof it.
2) Install new gen blower fan unit
3) Flush genny cooling system and install long life Shell Rotella ELC concentrate coolant

Good project Don.. FWIW, you don’t need extended life coolant in your generator, it doesn’t have wet liners. It sure won’t hurt, but I don’t think there is any benefit. If I’m wrong, we’ll hear about…..

IMO, around here Shell Rotella ELC concentrate is the most bang for the buck. Tractor Supply sells it for $15/gal. Its easy enough to totally flush the green ethylene glycol out of the genny cooling system and refill with this red long life stuff.
They sell Peak Fleet Charge(100%) for $16/gal. Dang good price too!
I don’t want to try and totally flush all the green ethylene glycol coolant that’s in the coach systems now. I read what Jon wrote about doin that, NO THANKS. Drain what I can and replenish with more green stuff, and put a new SCA charged filter on, send in a coolant sample for analysis, and do this annually. Tractor Supply has the regular green stuff, Traveller Full Strength Extended Life
coolant on sale for $10/gal until 10/25/15.What do you think?

Once again, why are you using SCA for a non liner engine?
-
I’ve changed my mind, I’m not gonna use SCA charged coolant for the gen. I have 2 gals of TSC Traveller Long Life full strength coolant to go back in.
I have the genny ready to pull from its compartment. I plan on replacing the fuel and coolant hoses too while I have it out to re-do the heat/sound barrier material.
Pics to follow soon.
