Generator Box Reconditioned

July 31, 2020, 09:15:22 pm

My generator box insulation was failing horribly, the deterioration was to the point I told the DW no more trips until it is repaired, guess what just became priority #1. My plan was to completely remove the generator, thank goodness for a tractor with a forklift attachment, remove the old insulation and use a self adhesive thermal acoustical product of some sort. I chose Design Engineering 050130 Boom Mat Under-Hood Thermal Acoustic Lining, 32" x 54" x .75" It took 3 sheets.

I called and spoke to the technical department about this use and what they recommended for taping the seems and edges , they suggested their cool tape or their Reflect-A-Cool Heat Reflective Adhesive Backed Sheets, 36" x 48" which I chose to go with so I would have more flexibility in sizing.
Amazon.com: Design Engineering 010412 Reflect-A-Cool Heat Reflective...
While I had the 10KW Powertech Isuzu generator out I replaced the following parts:
From Diesel Parts Direct, thermostat Part number 1Z8971606540, thermostat gasket part number 1Z8943259561
From Amazon, waterpump belt Gates 7335
Amazon.com: Gates- 7335 Belt: Automotive
From Power Tech, 4ea motor mounts part number 09MNTRED, Radiator Cap part number 03CR271
In addition I had the generator slide and frame powder coated and changed the Isuzu coolant.
Disclaimer: I chose the insulating product based solely on reviews of various web sources and since I just installed it I can't speak to the longevity or performance at this time. I will say it was very easy to work with and once the adhesive contacted the metal it was stuck.

Nice job! Mine was done by the PO. Do you notice a reduction in noise? I find mine is fairly loud and would like to find a way to cut the noise. Not a problem while driving but noisy when parked.

I didn't think there was any reduction. The original stuff was pretty heavy duty, I was amazed of the weight of the old stuff. I ran the genny 5hrs today to make sure the coolant system was free of air and full, still pretty loud inside however the coach was raised and had safety stands sitting on the rails if that mattered.

That thing looks sweet, Bill. Great job on the detail stuff.

Bill,

Beautiful (and thorough) job. I have the same coach, only 32 coaches younger on the assembly line. I recently tore out the old failing insulation and replaced it with new. I did not remove the generator and clean the compartment up as nicely as you did or replace the motor mounts.

I noticed two things from your pictures. First, I see you have a blank plate on the front of the electronics box. I assume all the guts were moved over to the first bay on the driver side. Are the two big (45 or 50 amp) circuit breakers over there as well? Secondly, I notice that, like me, you did not replace the overhead light. Did you remove the 12 volt power wire and if so, how far back up under the coach did you go?

When I was removing the carpet yesterday Foretravel had also installed thin soundproofing under the carpet for the drivers area. It was decomposing and I removed. My generator has the box but the soundproofing in it was also decomposing. I pulled it out last month. Bill you need to take a break finding more stuff for me to do. Nice job on your by the way.

Thanks Richard! Yes the electrical box had been modified by a PO, it contains the large breaker, voltage regulator and what appeared to be a reset button, I'm not sure what it does. The blank plate is actually mounted on a box with a air vent in the side.
The 12 volt wire is still there, I plan to install a LED strip light in the near future.

Good job. Tractors come in handy (I used mine to remove radiator), but I as able to disassemble the cabinet when I replaced the insulation a few years ago.

Great job. On the to do list this winter in Texas. Had my Generator fault yesterday, due to high temp I believe. Can't believe they didn't put in any gauges on these expensive items. Would be nice to monitor them from the coach. I have a big roll of Sound down Marine insulation in my bay waiting to go into the genny and engine compartment soon.
How much did it cost you to have the slide powder coated?I also need some welding done to the drivers side part that locks it in place.

Come on, you just took a photo of a new unit as it was being built. Can't fool all of us!

Really nice job. Bet it took a while. +++++

Don't forget,if you have the generator out,nows the time to change the end bearing,not that hard a job.

Bill & Marsha,
Nice Job! A lot of work, but worth it. We did our generator a few years ago when we replaced the pancake (generator head). We also powder coated the tray in black. Now for the engine area. The goal is to make it fire proof as much as possible.

Looks good John, I almost went with black as well! My engine bay needs redone as well, haven't decide on the product to use, fire proof is good also want to reduce heat to the bedroom.

Well I didn't forget however I didn't do it either, guess I didn't do enough research on all the items to square away when having the genny out.

Bill,

After seeing your pristine motor mounts, I have mount envy!

I have a quiet box and replaced all the insulation without removing the generator. Any chance of replacing the motor mounts without removing the generator? I think I might be able to get to the front ones; would that help?

Thanks,

Trent

I paid $150 also for sandblasting and powder coating.

One further question Bill. Did you have to replace any of the bearings in the roll-out tray?

I did not, cleaned them up really well and lubricated the best I could, they were really in pretty good shape once cleaned, they aren't used that much.

Trent, I'm not sure about your set up, my mounts have a 2 1/2" bolt through the center that sticks up through the generator feet an inch or two, the genny would need to be lifted to clear the bolt. Does your genny have excess vibration or have visible defects, if not I'm not sure I would go through the trouble and expense to replace.

Bill,

I replaced the insulation because of the total failure of the OEM insulation. I removed the quiet box panels and installed 1" of the Sounddown sound barrier with two layers of foam sandwiching a hard vinyl barrier.

My DW is still complaining about the noise from the generator, so I am going to try to add 2" of the Sounddown on the outside of the quiet box (where it will fit). This will make it about as quiet as I can make it, although new engine mounts would probably help with the vibration sound.
