Title: Generator comparisons
Post by: OKIE9ERS on July 20, 2018, 04:27:05 PM
In the early stages of generator shopping...
$10,000 for an Onan 10KW quiet generator...
$7600.00 for a Wrico 10KW...
Talked with Justin at Wrico--man that guy knows his stuff...
$500 more for a 13kw Wrico
$1000 more for 13kw Onan..
Is Onan thay much better, if at all?
Thats Northern Tool pricing on the Onans..
Thanks

What rpm do these two examples spin at?

1800 rpm trumps 3600...

Both of them will need some busnut ingenuity for the install in order to be truly silent.

If no one can tell your generator is running, standing around the coach at a rally, then you have succeeded.

Wrico can help you with that in ways Onan cannot.

Happy coaching!

I would go with the Wrico. They know generators. They've been doing generators for bus conversions for a long time. I have been at bus rallies when Dick Wright is on the phone in the middle of a party helping a customer with an issue. He is good.

Your user name makes me think south west Hot!
I tend to think the Wright 13k is your ticket then.
The 3cylinders and some with turbo get my vote.
Totally agree with BW the install and that silencing part is a big deal. 


Good day

Dick dosen't do a quite box like Onan he will sell you stuff to do one though,I bought a 13kw from Dick in 2000 it was ok I had a few problems nothing major but it ate shutdown solenoids @$275.00 a pop.
Onan is a good generator but I think 12kw is as large as they go,I am not a huge fan of PowerTech some really like those.The bus I have now has a 20kw EPS (Engine Power Source) in a quite box a advertiser here it has to be the best generator I have ever owned IMO with the Smart Start.Me I would buy used or old stock and stay away from the Tier 4 engines

Personally, I wouldn't ownan Onan anymore since Cummins owns them. Crazy parts prices for engine repairs. Dick Wright can be great help if you have any issues. I would think 10 kw should be more than enough unless you are going to spend a lot of time at high altitude which will sap generator power.
Whatever you purchase, make sure the generator head is brushless..
Scott and Heather have had great service from two Honda gas generators paralleled.

Great thing about ONAN is their service and parts network no other brand can touch it

I second Floyd, Wrico 13k.  10K will only give you 40 amps of service, 50amps on the 13K for a total of 100amp service or same as your power cord.

Thanks all---
Yea Floyd, 110 plus today in western Okla...ugh..
I did like the personal touch from Wrico---they called me back and gave me way more info than my newbie mind could even grasp...
Considered used luvrbus, but worry about buying something on the verge of problems...really dont want generator issues..
Not crazy about the thought of gasoline either...
So...probably leaning towards the larger wrico...
Thanks again!!

Any good generator will go 15,000 to 20,000 hrs with not many problems.I work on a bus that has a antique 6.5 gasoline twin cylinder Onan runs 1800 rpms it has over 13,000 hours, a fuel pump replacement is all that has ever been replaced  since 1984 not to shabby

We got a 13kw Mecc Alte generator head from Wrico to mate to the Perkins in our 4106. Great generator head and pleasant experience.

You guys with the older generator are better off ,they added so much stuff to the Tier 4 final on the little engines it's a nightmare plus higher prices too.I have a friend that owns 2 BobCats with the tier 4 Kubota engines they are always in the shop.They are going to be expensive to maintain for bus people every bus owner needs a tier 4 engine in a bus with a old 2 stroke engine it will be a learning curve  ;D

That is a good generator Martin is the most preferred generator for entertainer coaches running 24/7 .When buying a generator never buy the minimum. I learn that on my 13K over size because altitude and heat,they lose 1%  power at every 10 degrees over 85 degrees and 3.5% engine power at every 1000 ft in altitude.I go through this daily when people do not understand why their generators ran 2 AC units fine till they reached AZ with a 115 degree temperature

I have a Martin 10KW since 1999.
Works GREAT.
The only problems were a hour meter, and a voltage regulator.
Both problems were my fault by not airing out / cooling out the generator compartment correctly.
I didn't have forced air passing thru the compartment to clear the gen head heat.
I just cut some access holes to rad area so air first is pulled thru the compartment before getting  to the rad.
That's it.
Frank

The Onan name is gone now they are Cummins Power,probably the reason Onan has 75% of the RV market is because of their service network it is well established across the USA

I have a 12.5 Kw Martin that I bought in 1996, still okay. Martin builds units for the military, and they are very solid. The catch is they are in Ohio for you guys out west, and those nice 2 cycles in Idaho are too far away for us in the East. A rebuilt used model is probably the most cost effective generator, and you dodge the Tier 4 junk.

I visited the guy in Idaho that has all the 2-71 DD generators,he bought those from Union Pacific Railroad they powered the refer cars for years and he has a lots I mean a a lot of those

I noticed they have four different levels of pricing giving everybody a price point. It might be nice to listen to 2 cycle music night and day.  ;)

Lol you would have a built in vibrator,the 2-71 would shake the sheets off the beds

Those generator sets aren't that good a vibrator. They run at 1200 rpm.

They vibrate even at a idle AT&T has a few of those I pickup parts that have vibrated off   and reinstall parts like the mufflers and you cannot keep a rain cap on 1.The 2-71 is the happiest at 12kw 65 hp you bump one up to 20kw they don't like it much,they have a large vibration damper same size a 6-71  they are not real smooth

I have a Powertech 10kw Marathon alternator and Kubota 4 cylinder engine. Bought in 1993, has about 1,200hrs on it and have done nothing to it (except change the coolant once and oil at 150 hours). Good Luck, TomC

Just curious what  "tier" means when referencing generators? power output, quality, ?

Level of emission control for off road engines,dumbest thing CARB and the EPA ever came up with for those tiny engines.I looked at one in a new RV no way would I go there

The kubotas that Wrico are selling now are tier 4
Title: Re: Generator comparisons
Post by: luvrbus on July 21, 2018, 04:35:20 PM
I didn't see any Tier 4 final engines on his website only interim Tier 3 and 4 he can sell those for a little longer,someone pays a fee who and how much I don't know. Same deal International got away with for a few years they just paid $1500.00 on each engine and kept selling in those in Monoco RV's and I/H trucks,now you see nothing but Cummins in the Internationals,There is a break in the HP rating for Tier 4 final for another year but I forgot where the break is I am thinking 22 hp. The one I saw in a Prevost had all the crap including the DEF tank mounted on it and was a Kubota turbo charged

I had Wrico build a custom 3 cylinder Kubota with 12kw power head to keep the generator (without radiator) at only 36" long. I bought it several years ago so it is still mechanically injected. Now all new engines are electronically controlled (no thank you). Good Luck, TomC
