We have a 1973 GMC Canyon Lands with an original 4.0 Onan Gen which seems to be worn .. still runs but very smoky and not putting out full power.

Does anyone have a suggestion for the best replacement. We really like the current one as it is very quiet and if it was in good shape, would fulfill all our needs.

Any suggestions would be welcome.

Thanks,
Lynda and Brian Bowden

Good Morning and Welcome.. 1-877-275-4462 is toll free Jim Bounds http://www.gmccoop.com/ . There is a chance the carb is out of adjustment. Too rich will smoke and the RPMs controls the output. Jim would be my first call. This might not be your problem, but the best place to start.

With out a doubt, the best thing I have ever done since I purchased my GMC
over seven years ago was to replace the Onan with a Honda EV series gen set.
It fits nicely in the existing compartment. Runs real quite and has a lot of
power. I can't say enough good about it.

This is a tuff one, I guess it all depends on how much you want to spend, Here at MGM-GMC, we use Generacs, i have installed 28 Prime Pact 50 g, and 7 Quite Pact 40 g Generators, i also have installed 4 Honda ev6010 and 1 ev4010.

For the money, I'll stick to the Generac's, they come complete with muffler, wiring, and remote panel. the hondas, these are options you have too buy.

the prime pact 50 g fits into a 23 foot just fine, got 7 of them in those and no problems at all, the ev 4010 has 30 amp service, the 50 g has both 30 and a 20 amp service, so you can run 1 a/c on the 30 amp service and the secound on the 20 amp service.

the ev4010 is rated @ .66 gals per hour @ half load, per Hicklin power systems, the prime pact is rated at .46 gal per hr @ half load.

cost, according to honda, the ev4010 is 2,739.00 per Generators.com, there lowest price and yes i'm sure if you spend the time., you might find them cheaper, plus you need to purchase the muffler and the remote starter switch.

the prime pact cost 1,829.00 complete shipped to your door and no tax.

both take about the same time too install, Generac has a 3 year warr. no hour limit parts and labor.

both ev's come with a 2 year warr.

I haven't had too use the warr on the honda's nor the generacs, i have had mine in for 3.5 years now and have a little over 400 hours on it, we camp alot out in the desert and go bugging around so the generac runs all day and nite, VERY HOT OUT THERE.
go to keep the ac on.

My thoughts are, It all depends on how much you want too spend.
and secound, Generac : made in the USA, ev's from
japan,made in :China.

Miguel,

You didn't mention the Generac 36G. Have you had any experience with
them? If I need parts (like an A6060 board), can you get them?

How in the world do you fit a 50G into a 23'? Enlarge the compartment,
surely, because the advertised dimensions greatly exceed the interior of
mine. Do they slide out, or how do you service them?

Remove tha back wall, seal it up and slip in the 50g tray for fit and drill the holes needed , than reset the generator back into the tray and slide it in, trust me, it can be done, now as far as the 36g, i have not worked on those, i did not want too install them when they were made, nice unit but i just didn't want the headache that i thought would come with them. I know a few SOB's that have them and they swear by them, (notice i did not say "swear at them!!) they love them so it's a crap shoot.

I personaly perfer the Q/P 40 g myself but all i need is 30 amp service, my royale was set up for that so putting a monster 6kw @50 amps was not needed, Bob Lamey was at my shop the other day or last friday, i asked him to bring his DB meter, the Q/P 40 g levels tested @ 70 DB @ 15', the honda ev4010 was ,well louder and the 6010 even more but thats all in what you prefer, i like American made products, i know that alot is being made in China and there are things we will just have too use from there, but i try to buy as much american as i can.

Please everyone, understand, i think the hondas are wonderful, great and what ever else good that can be said about them, but the Generacs are just as good.

The 36G was the Pinto/Vega of Generac, but that does not mean all the other stuff they make is junk.

Oh one more thing, the 50 g runs @ 2570 rpm !!!

As always, thanks for your time

Thanks, Miguel. I'll have to re-measure everything if I give up on the
36G. My compartment may be smaller than standard; I didn't leave any
extra room around the Onan when I remodeled 10 years ago. Not sure what
I'll do if I have to give up the electric cord storage compartment (and
vacuum cleaner storage inside) if I have to use that space behind the
compartment for the generator.

I would really like to see a complation of what the owners think of Generacs after using them a couple years.

The BusNut guys called them junk and there were a lot of stories, which I have at one time mentioned here about bad quality control, bad support, bad warranty, they even said they were too light to use as a boat anchor.

Nothing against Miguel, and his great service and if there are no complaints, GENERAC must have taken some big steps to improve the company/generator equipment. It just seems too much to fix for too much money(considering how busness is today).

I will admit, on this site, very few are talking of bad experiences, but go to busnut site and they laugh you off the board.

how can there be two different views of the same company/equipment?

I will admit, because there are few nay sayers here, I have kinda thought about a Generac but only for two reasons, I have heard you can get them cheap, and because you can get them cheap, consider them throw away when you need repair.

any thoughts? I am not flaming nor saying anything agianst Miguel and his fine business but I am confused on the different opinons between the two web sites.

For those of you out there who are concerned about the quality of products
that are made in China for western companies here several personal
experiences for you to consider.

1) The vertical stabilizer for the Boeing 737 is made by the Xian Aircraft
Factory in Xian, China. I can assure you the quality meets Boeing and the
FAA standards. How can I say that you ask? Well when I was a Field Service
Representative for Hamilton Standard I worked with the XAC to upgrade the
Y-7 aircraft they built with Hamilton Standard props (fitted to Pratt &
Whitney engines) and air conditioning. I routinely ate lunch with the Boeing
reps that were based there.

2) Pratt & Whitney had a contract with a company in Chengdu, China to make
jet engine turbine blades (can't remember the name of the company). My
office mate in Hong Kong was a metallurgist who worked for P&W and visited
that company regularly. I can assure you those parts met P&W and FAA
standards.

3) During my tenure as a HS Field Rep based in Hong Kong (1991-1999) I
traveled all around China. During those travels I met a lot of western
company reps that were assigned to or routinely visited companies in China
to assure the quality of the products that were produced there were up to
the same standards as those produced in their respective countries.

I'd be willing to wager dollars to donuts that Honda has company reps at the
factory in China checking to make sure the quality meets their standards.
Come to think of it don't they have reps based at plants in the USA where
their cars are made? It is also quite possible that the generators are only
assembled in China and the parts come from Japan.

You might find that the EV engines are made in NC.

if the ev motors are now made in NC then i stand corrected, as i said, there is nothing wrong with the hondas, just cost 2x what the generacs cost, the generacs are made here which means tha bulk of that money stays here in USA, not sent back too Japan or where ever.

Alot of good products come from japan, china and even mexico, that was not my point, i would rather buy american made from an american co.

you all get whatever you want, i have had my 40 g in for 3 1/2 years now and run her alot, never had anything go wrong.

It's like GM, i never would have purchased a car from them in the 70's and 80's, once they found out that they were messing up , they got there poop together and now make a good car, but thats all in a mateer of what one likes, i have aqn 1994 chevy 2500 pu, 228,000 on her and she still runs great, 2003 STS, 78,000 perfect, 2004 cts, same thing, 2004 duramax 121,000, no problems at all, now some of you out there could buy the same thing and have noting but problems, who knows why but again, get whatever generators you feel will do the job for you.

I meet a man who owns a GMC, everyone knows him that owns a GMC, he has a 50g in his unit and he seems too like it very well, put it into another persons GMC and they hate it???.

well thats it for me, my only point ways that the generacs cost half as much and work perfect, look, i install any generator you want, its your GMC.

Thanks

We run a Generac and have for over three years.
The unit has 187 hours on it.
We had a starter bolt work loose and Generac paid for a new starter and all
the labor.
We had very good service here in San Diego.
We did have a SOB in the 80's with a Generac and it was very noise.
This newer model is very quiet.

I replaced my noisy, old, still running with 8k hrs on it, oil leaking
Onan with a QuietPac 50 and got good service from it.

I had a starter fail after 100 hrs and Generac replaced it under warranty
at a FMCA rally. The warranty was better than Honda's, and the muffler
and remote switch was included in the price. I never had another problem
with it or Generac.

That's good, especially since on the 36G, even just tightening a loose
starter bolt would be a significant undertaking. Knowing, as I do now,
where those bolts are, R&R, plus removing things to get to those 2
bolts. would probably be a 2+ hour job.

Fact is, I probably could have gotten my original problem fixed under
warranty if I'd pursued it sooner and made the 150 mile round trip to a
repair location.

The shop had to pull it out in two sections.
The repair cost was over $300.00.
Paid for by Generac.
We have a shop here in San Diego
"El Cajon CA" his only repair service is R V generators "All Makes".
Very good people to do business with clean and fast.

I had a bridge rectifier fail in my Generac 50G at 59 hours. New part was 18
bucks and then got 2 spares from Ken H basically for free (Thanks Ken). It
might have been a heat issue so I remote mounted it closer to the access
door and then added more vents to the enclosure. I'm sure it will be OK now.
We have run the unit in 110 degrees ambient for 5 and 6 hours at a time with
no problems.

The PO put in a Generac NP-66G in my 26ft GMC. I'm not sure exactly how many hours are on it since the hour meter was broken when I first got the coach.

I've only used it about 50 hours in the last 5 years, so it does not get a lot of use. I probably have used it more during power outages at the house then on the road.

I may go a couple of months without ever running it, but it always starts up easily.

The only problem I have had with it was a bad low oil presure switch. It cost $10 from a local generator repair shop.

It runs fairly quite.

Funny thing is, i got onto busnuts web site, and 90% of the Generacs they are talking about are Diesel units, infact, 75D's, the other 10 % were older gas units.

Maybe generacs at one time were junk, but so were the last 3 american made cars, but times change, as i said, i have installed a grip load of these Generacs and to date, only had problems with one unit and found out what that was and Generac sent me a new unit right away and paid me for my labor, the problem was: the customer purchased a 50 G from me, but insisted on installing it him self, after weeks and alot of phone call to me, he started it up and it ran for a few and would shut off, time after time it would shut off, i asked him to bring it in and let me check it out but said i was too far away to drive (23 miles), contacted another GMC and the bright idea of disconnecting the low oil press. switch was disconnected until they both damaged the motor so bad that it finally started to smoke, he never added oil to the crank case. he admitted what they did, i contacted Generac and they said they would send me another unit free of charge however i would have too install it, a
nd not the customer.

I called Honda on a 6010 that started to hunt and man that took an act of god to get anyone to help me. again, i have installed 4 6010's, and have pulled out 3 of them and have the 4th one at my shop right now to pull out, anyone can come to my shop to verify that it is being pulled out and is going to be scraped , i also installed a microquite 4kw that i also pulled back out and installed a 50G, the reg. on the onan micro cost 380.00 and they seem to go out often, customers get upset and just cannot believe that Cummins/onan parts cost so much.

I would like to make it very clear, i do not sell Generators, those that want a new generator ask me and i give them the info for all of the units that fit, and i tell them to make the purchase them self as this gives them the direct warr. on the generator, next thing i know, a truck pulls up to my yard and there it is, whatever generator they picked. I never say that the Hondas, yamahas, kohlers, onans or generac are better than the others, i let the GMC ownwers decide, like wheel spacers, i will never sell those to a customer, not because of anything other than, they do not work on every GMC, nothing too do with the bearing load, i have repacked many GMC's with many miles on them and the bearings look fine, it's just that they need to decide if those are going too work for them.

At my shop, i try to stick to stock as much as i can, headers, final drives, spintec 3" exhaust and there off and running, you want an MSD whatever, i let them get it and i just do the install. Now for those of you with the MSD stuff in your GMC's, if they work for you, Great, and i'm not saying that they do not work, i'm saying that if that is something you want, then get it and i'll install it for you.

Funny thing is, i was up @ jim k's shop one wekkend and saw a GMC that had a 75G Q/P stuffed in that hole, hell i wondered how they did that, i asked the owner and he told me that they had to lift the body and add 2" lift kit to it in order to make it fit. heck 7.5 kw, now thats alot of power, way more than ever needed but thats what he wanted and thats what he got.

well i'll stop boring everone, have a great Sunday and God be with you all.

Just my saying it doesn't make it totally true but the Forge for a lot of their small engines is 20 miles up the road from me. They have a number of plants in NC and SC for non automotive products.

I know my EU2000 is made in China, i have had it too the repair shop 3 times now under warr. and upon opening it, there is a sticker saying Made in China for Honda Motor works.

the problem with that unit is, sand gets into the on / off switch and will not make contact so she will not start, change the switch and ready to go, the problem is, you have to take it apart so much that after the warr is over and it goes bad, i'll just throw it away and get another unit.

I had an origional 5 kw generac in my '92 Class C. Started everytime and ran just fine.

I also know an applications engineer at Onan / Cummins, he says they put a generac (I don't know which one) on a load test, full load 100% duty cycle and the engine case split in two pieces...

I'd still buy a Generac no problem

I'm sure this has been discussed before, Does anyone know of list of
how the GMC should be stored - off the ground or not? and How?

Thanks, Rich

>>>>> Funny thing is, i got onto busnuts web site, and 90% of the Generacs they are talking about are Diesel units, infact, 75D's, the other 10 % were older gas units. <<<<<


I have not visited the BusNut site in some time now, but when I did, most Generacs considered were gas. Since the GMCmotorhomes use gas for the GenSets, I thought this was a concern.

I think repair should be minimal but they were talking problems from the git go. Now some may not think much of replacing a bolt that takes two hours to disassemble the unit to replace or whatever, it is your time and time is money or in retired persons thinking, time is travel time.

I recall one of the guys at work complaining about his Generac, that he scraped. The RV was stored for the Winter, the Generac was working at that time. Come Spring He said the clutch was froze and he could not start the GenSet. Turned out the clutch froze from sitting and GENERAC told him the warrantee was void because he failed to properly maintanance it. The mantainance they were speaking of was the Generac had to be ran once a month every month to keep from freezing up from corrosion... He was, majorly upset.... I dont think he bought another Generac.

I only posted the original post to learn more about the long term of the generac. Not to put anyone or a business down. Generac equipment will speak for itself as all equipment will.

Thanks for any comments that were given, seems to be a 50/50 reliability.

Thanks, Gary.

Nice installation. Unfortunately, when I rebuilt the coach in '98/'99 I
didn't plan ahead for any modifications in that area and they entail
MAJOR rework now. My compartment is exactly the width of the access
door and the top slopes from door height to about 5" lower at the
interior. Very small. :-(

I just thought of something here, If a 2 dollar bolt came loose and that time is too much too much time for a small repair, heck we all better throw our GMC into the ocean and make a reef for the fish, because we spend alot more time keeping these things running, alot more that a 2 dollar bolt, wish my GET MORE CASH motor home only had a simple lose bolt, but it seems like i'm always fixing something in it, but should i get an SOB!!!

All GMC's should be stored in Arizona, new Mexico, or southern
California and attended to daily by the owners..........Terry

I bet I could rework my compartment to match what Gary has done,
however.

Ken has recounted the problems he's had with his 36G, and I should do
the same. I haven't had the sorts of problems he's had, but I have had
some issues.

The most annoying is that my Generac won't start up without at least
half a dozen attempts. I press "Start" and the engine fires up and
then shuts down after one second. This is repeated many times. Then it
starts and the RPM's vary widely, sounding to me like the throttle
control chasing its own tail. Then it shuts down. Finally, after often
half a dozen attempts, it starts and runs fine. My suspicion is that
it is not bypassing the oil pressure switch during the startup cycle.

It does shut itself down for no apparent reason from time to time. It
may be too much heat, or vapor lock. The generator did shut down once
within a couple of minutes of the main engine shutting down, and that
could be a vapor-lock situation. That's happened twice now.

I have added ventilation to the Generac to enhance it's air flow, both
on the intake and exhaust sides, trying to prevent an overheat, but I
still had a shut-down on the way up to Flagpole Knob in June, again
associated with a couple of unanticipated shut-downs of the main
engine during that slow crawl (<5mph) up the rough dirt road to the
top of mountain.

Other than that, it's run just fine, including running for hours at a
time while parked and while driving on the highway.

Rick,
When I put my fuel line into the gen compartment I used AN stainless and put
a loop in the line that would trap fuel. I think if the fuel runs back out
of the line into the tank it takes several attempts to start the genny.

Might be something to look at.
