The heathen chinee genset is in the coach! It isn't bolted down, nor is it hooked up electrically, but the dam' thing is in the bay. The bay door closes without the fan interfering. Some days I've been living right. I was going to remove the yanker cranker to gain a bit of space, but there's several inches more it can move to the rear, so that isn't necessary. Plus, I like the idea of when everything electric goes Dixie in the coach, I can hand crank the genset and using it revive the electrics - an option not available with the Onan.
I had to disassemble the thing a bit to get it thropugh the door - the air cleaner box had to come off. I could remote it, but it would be a pain, I think I'll just put it back now the set is in the bay. The muffler will be remoted under the coach. While it could be replaced where it was, the heat shields for it attach to the original frame, not the set, and besides I don't want the extra heat in the bay. The set is tilted slightly sideways to give better clearance and the rear is raised slightly to allow it to slide rearward a couple of inches.
I'll simply use 12V relays to follow the remote panel inside, so the set can be cranked inside the coach or from the rear bay.. or by yanking the yanker. I believe the door fan will move enough air through the bay to keep it reasonably cool. If I have heat problems, I'll add some baffling to redirect the fan air. I'm going to get the placement exact, then mark the mounting beams, remove the set from the isolaters, and bolt the beams down in the coach. Then, replace the set on the isolators. There's sufficient space above the set to put taller isolators if need be. Testing will be done with the contractor tank on a stand until my pulse pump gets here. I'll build a small panel to go on the upper edge of the bay door to hold the relays and circuit breakers. Pictures later tonight.

"Tonight" turned out to be a relative term. Today sometime hopefully. I consulted with Ken H on getting pulses for the pump. I want to see if it can work without an electric primer. I can put one but it complicates things a bit. Time and use will tell.

I wasn't real happy with the clearance, so I set the thing up on a pair of 1 inch box stock. Now it's got plenty of shake room.After conferring with Col Ken, I think the move on this one is going to be a hole drilled in the dipstick with a nipple glued in to run the pump. I'll try the breather in the rocker cover first, but I suspect there won't be sufficient pulse there.

Pete,
The generator comes with gravity feed from the tank mounted at the top of
the assembly. I calculated that as about 0.084 psi. No available electric
pump nor regulator could control down to that after pumping from our
tanks. With the least pressure I could get, I still had, literally,
gasoline vapor coming out of the exhaust pipe. So I went to the crankcase
pulsation driven diaphragm pump used on many lawnmowers, etc. It works
great. I do still have the lowest pressure electrical pump arrangement I
could devise, but it is powered only from the starter, thus acting as the
choke. That's worked well too.

The option would be a header tank with an electric pump and float switch. A tank of gas in the generator compartment? None fer me, thanks.
After looking at options for the muffler, I ordered a 6 foot length of flexible exhaust pipe - nobody locally had any in 1 1/2". I'll bolt the muffler up to the frame underneath, and use the head pipe with two flanges cut in half to connect to each end of the flex pipe. I was gonna have my exhaust man bend me up a custom pipe with flanges, but it would still have to have a flex section in it - the muffler hard bolts to whatever. The 1 1/2" flex pipe fits nicely in Heliax<tm> hangers so I can keep it from flopping about. Pipe gets here next week, and I have a show the next two weeks, so it may be a bit before it's finished. I'll add a jumper to the new power panel so I can run on the 30 amp power cord. Just have to remember to turn the water heater off when the A/C is on. Meantimes I'll build up the relay and breaker panel and get it in the bay.

It is in the coach, and bolted in place. I raised it an inch and a half off the floor of the bay, and angled it slightly. Both give better clearance around the set. The widest part is the cylinder head on one side and the starter on the other. You could achieve the same clearance by rotating the set clockwise several degrees if you wished and not angle it side to side... but I'd rather keep it level. It is mounted using the same beams it was mounted on in the original frame, which keeps the original vibration isolators. I've six feet of 1 1/2" flex exhaust and a pulse pump on the way, due next week.
This install was made easier because much of the bottom of the bay has been removed for the Generac which was fitted. I've a roll of flashing metal, I will probably close off much of the opening to keep water and crud out. The fit was pretty much 'by God and by gory' using materials I had on hand and existing holes in the coach. Everything is bolted to a frame member except the right front, which is bolted through the bay floor. Given the experience, it would be a two day job. I spent a week, mostly because it was cut n fit, and once I got the heavy thing in the bay I didn't want to remove it.
It could be mounted on slides in a 26 foot if one wanted.
Currently 600 bux for the genset with tax and coupon. Maybe a hundred more for materials if you don't have them in the junk box. Ten cents a Watt ain't bad.

After 11 days in two weeks of shows and traveling, I'm back on the genset. My muffler guy is welding me a pair of 1 1/2" nipples onto a pair of flanges I made to mate up to the exhaust pipe and muffler. I've a length of 1 1/2" ID flex exhaust hose. I believe at this point I'll bolt the muffler to the crosspiece which holds the bumper shocks just inboard of the driver's side shock. I've three 12V relays, two to work the inside panel start - stop, and one to run the compartment fan. We'll feed the start and stop fused 12v, the change being we will have to hold the stop switch down until the engine stops... it's simply serised with the run switch on the genset. The start parallels the momentary start switch on the set. The fanb relay will run off the 12 V supply from the generator itself, and will turn the fan relay on as long as the set is running and producing 12V. The fan itself is fed via that relay from the house 12V bus through a 30A fuse. The genset 12V also runs the Hobbs clock and the light on the remote panel. This setup allows the genset wiring to remain unchanged, with the exception of one series connection. No cutting of wires required, no rewiring of the inside panel required.
AC wiring needs only three #10 conductors from the genset breakers to the Shore/Generator relay, and from the relay to the new AC panel.I may replace it with a manual switch. I'll keep the 240V receptacle which came with the genset and put it on the new panel. I've a 'fool killer' which I used on the now defunct Yomamamaha genset to power my home when the commercial power fails. I use it to backfeed the house via the welder plug in the garage, with the main panel main breaker turned off. All I have to do is move the GMC to the garage door and plug her up. I've ordered a 30' 6-3 and ground shore power cord for the setup so it works on a 50Amp outlet. The existing 30A cord gets a receptacle on the bitter end, so when only 30A service is available, I can plug into it and feed both sides of the AC panel, although I'll have to be careful of load to not trip the pedistal breaker.
All that's left is placing and feeding the pulse pump.

Eight more pictures - exhaust and muffler detail. I hope the muffler doesn't drag, perhaps on a 23' it will clear. Otherwise, relocation will be the move... but relocating it will be somewhat of a PIA. Of the needed parts, the muffler came with the set. The gaskets were the cheapest exhaust gaskets Advace had ($8 with discount) I cut the two I needed out of one of them and kept the other for the future. I made the flanges out of a piece of 1/8 flat steel I had, and had my muffler guy weld the 1 1/2" OD nipples on to fit the flex pipe - $10. Couldn't find 1 1/2" muffler clamps so I used band clamps. Ain't real pretty, but is real tight which is what I was aiming for. I think in this length the flex pipe is rigid enough to stay where it's located. If not, I'll clamp a mount or two on it.
Next up is the fuel feed and associated pump.

Johnny,
You keep saying you've posted photos, but I haven't yet seen a link to
where -- perhaps you're only putting them on the forum? Us old
died-in-the-wool emailers will never find them. :-(

And, I rather email too - but something or other kills sending it to yahoo. Patrick 'splained it, basically "It won't work". If they ever fix that, I'll go back to email.

If you are ever in a cold damp area, you will freeze up your carb on the
new generator. Does it have a 'heat' supply or will you be making one or do
you never stray to cold damp areas?

There are several answers to that, Mike, not necessarily in order, and to a degree mutually exclusive. One, you don't have to be in a cold area to freeze up a carb... I managed it in 65 degree air over Perry, Florida in a run out 150 one fine afternoon. When I figured out what was happening and hit the heat, the dam' little thing nearly quit on me before it cleared up. Two, I don't spend a lot of time in cold damp areas. Matterofact, I turned down an offer from the CBC because we lived at the time in Tulsa, neither of us like the winter weather there, and EVERY place in Canada was/is substantially north of there. Three I have to wonder what contractors in the Great White North do with their gensets - I'm thinking either Harbor Freight or Northern Tool or their Canadian equivalents sell there, and these things are ubiquitous. Do they simply not work ten months out of the year? Four - and this is probably the telling point - the engine pulls fumes and blowby and whatever directly from the rocker cover into the airbox on the carb side of the filter through a 3/8ths hose about two inches long. I suspect it gets enough heat thereby to keep it from freezing up. And finally, the greatest use is liable to be running the roof A/C on the road. In cold damp situations, I won't need the roof A/C anyway. I don't dry camp except one show per year in Charlotte in late May/early June. every place else has shore power.

Johnny,
If you haven't tried GMail, do. It automatically "threads" on Subject: and
hide past posts unless wanted. To me it offers the important benefits of
the forum with the best of email.
