Hey Guys; I have to pull a genset,12 kw Onan and wanted to find if anybody has or engineered a slidder tray for one? I don;t want to put it back in without a slider,if you know what I mean? I only have about 4-5 inches above the unit to get to the relays and that ain't enough to stick my head in, LOL I have a bad relay that keeps the fuel solenoid in and it is ok but the relay isn't so I have to pull it out enough to see in the panel and find the relay.. As usual,thanks in advance. Gomer | ||

Hey, Gomer! Yep.. BTDT. Post or send me a pic or two of your unit and how it is now mounted? I have just re-done mine...third time... to get the most "user friendly" (two different generators)way of servicing. I suppose if I were to dwell on it, I could do it even better, but that is not in the equation just now. Maybe I can do that "dwell" for you....and then go re-do mine ....again!!!!...  What's the Clinton Acronym?....KISS, as I recall. RCB | ||

KISS stands for keep it simple, stupid. meaning to do something very basic, not elaborately. All of the hi tech stuff may be cool/fun/interesting until something goes wrong with it. A model T can be fixed with a screwdriver, pliers, baling wire and bubble gum. A 2010 car is going to have to go to the shop because of all hi tech systems on it. About all you can do on a new car is change the oil, air filter and maybe the spark plugs if you are lucky. | ||

Marvin...still no e-mail... Might check the address. It is correct as listed in the top part of my "profile"... have no idea where the "comemail" came from. Re"noise"...one of the issues I dealt with in the re-do. RCB | ||

I have a double slide for sale if anyone needs one. I moved my generator to a new location and didn't use the slideout again. The slide when closed is 36x24x3.25. Jack | ||

Silly question but how do you handle the exhaust when on a slider? | ||

Many have a piece of exhaust that is spiral seamed and it is flexable. When the gen is in, it is in a large loop and that allows you for a foot or two of motion with a slide. Another style is an inner and outer tube that slide on each other with an exhaust donut of sourts. For the slide itself there are a couple of styles. Most common is for a gen that is mounted sideways where you can see 1 side of both the head and the engine. Some gen. are put in deep, so the pullys and the front of the motor are facing out. This is how ours is and it slides on a set of very beafy full extension drawer slides that were reinforced with angle iron. Putting the gen in deep, like ours, makes it a bit more difficult to get to things but it allowed the converter to subdevide that bay and put a wall between the gen and its radiator. This makes everything quieter because the exhaust fan for the radiator is not discharging noise along with the hot air AND gets it all into 1 bay. However, IMO, longways is way more common. It is easier to access things but unless you are willing to sacrifice additional space in an additional bay for the radiator it will be a bit louder if it stays in the same bay If you were a welder you could very easily copy a slide for a sideways mount with some measurements. On a sideways mount they are mostly anlge iron and steel rollers. Most professional conversions are also equipped with air bags for the generator. IMO the difference in vibration and sound is very very slight with and without those bags aired up. IMO not worth the fuss. I rebuilt our gen bay pulled the whole thing out and redid everything. I found "corrigated" exhaust pipe to replace the original spiral seamed type, I upgraded the insulation to a mylar coating I put LED lights in the bay new fuel line ect ect. Fun project. Thumbs up from me on a gererator slide. Either wat you choose to install a gen it is deffinatly a nice feature to have. | ||

I found that a lot of noise comes from the air intake. So I am expermenting with putting a muffler on it with exhust pipe welded and clamped together. Roger | ||

When you have the intake for the gen radiator and the exhaust from that radiator cooling fan both cut into the bottom of the bay there often also has to be a baffle directing hot air off the radiator away from that intake or it will cause overheating. Those who are using gas engines should either have an exhaust fan running prior to start up to vent possible explosive fumes or open up that bay before start up to be safe. That exhaust fan prior to start up is also a good measure on a deisel too. I have been kicking around hooking one in off the wire for the glow plugs so any time I preheat it vents. My old grey foam was very deteriorating, crumbling, it had a thin piece of lead sanwiched between one inch foam either side. I replaced it with the same PLUS a white mylar coating. It looks great and is easily wiped down with 409 BUT IMO the foam can absorb less sound covered in mylar. IMO the quietest gens have the radiator and its cooling fan isolated, use the bumpy egg create style exposed foam, use a second set of insulated doors just inside the bay door and run the exhaust out the roof. 5/8 fire rated drywall behind the foam is also good for safty sake. | ||

My gas Honda EV6010 is mounted on a 1" square tubing cradle with runners which slide in two channel irons and bolt in with four bolts. Simplicity itself. I chose not to use wheels or shelves on rollers because I figured I would be sliding it out so seldom that all that stuff was a waste of effort. However, my exhaust, radiator and everything else except the connections are on the cradle. The genset is also exceptionally well mounted on rubber feet from the factory, no vibration whatsoever. I have service loops on the fuel line and battery cable, the other electrics have quick connects. If I want to remove it completely I have to disconnect the fuel line and battery cable. To just slide it out just for access I don't have to disconnect anything. One point, if you install a fuel hose service loop be sure to keep it below the fuel line level to avoid air pockets. | ||

Roger, install 90 bends in the intake or use the sprial steel ribbon in the intake hose cuts out the intake noise. good luck | ||

When i went boondocking last summer, i found some sliders from dining table that had been burnt in the camp fire. Heavy duty too. I couldnt believe it. | ||

I installed my generator in a bay horizontal to the bus and built my slide using 2 inch square tubing that I found in the dumpster at work. It was a discarded ceramic tile display stand. I welded heavy duty roller bearings that I bought from McMaster Carr on the frame and that frame rolls inside of home made steel "C" channels. The exhaust is down thru the floor and when I need to slide the unit out, I disconnect the exhaust via a union or coupler that is just above the floor and that was recommended by Fred Hobe! It has worked very well since day one. As for air intake, I used a squirrel cage fan on the curb side of the same bay drawing air from the road or floor. That air passes thru a home made bulkhead that separates the bay in two, forcing air directly at Generator head. Attached to the generator is the radiator and another fan that exits all hot air thru another bulkhead going forward into another un-used bay and then directed downward thru the floor via home made duct! I originally installed egg crate foam on all walls and although it has served me well, I plan on changing the bay insulation. Maybe even use a sound box of sorts only to help keep it cleaner, not quieter. Even the way it is, it is VERY quiet until I open the bay door where it sits. Up stairs, you hear a slight hum with a slight vibe when shutting it down! I never once had an overheating problem as it constantly runs 175-190 on the hottest days! It's a 12.5kw Kubota from Wrico. If you need pics I can supply you them showing start to finish! Ace | ||

As for the exhaust, you can use a half circle loop of flex pipe that can move when you roll it out. Make sure you use stainless steel. It won't stiffen up over the years like galvanized does. Napa carries it, even in small sizes as well as other vendors. Mine has a squirrel cage that pulls heat through radiator and blows it out the bottom of bay.Uses a 110 volt motor that comes on as soon as generator makes voltage. One benefit besides noise reduction, is if you have exhaust leakage, you wont get carbon monoxide inside coach. The only down side is that this setup takes more space. My 4905 has the generator mounted parallel (10kw power tech) to side of coach, just inside baggage compartment. Don't need slide out this way. Everything is easily accessible. A partition is installed on back side for use of rest of bay from other side. Whole compartment is lined with foil covered soft insulation. | ||

Marvin...after a bit of consderation, these guys are way ahead of me ...because I do not have a "typical" bay situation. Mine is trunk mounted..floor 12 inches below door opening. What I would offer is, no doubt, not any way connected to your application... FWIW RCB | ||
