Gen hours

[Isaac-1]

I would say that is a lot for the mileage, my 2002 coach had 75,000 miles and 500 hours on the generator when I bought it in 2016, it now has about 94,000 miles and 1,126 hours on the generator (I know the hours as I just did an oil change) with about 150 of those generator hours getting put on this August while we were driveway camping by our house during extended power outages after hurricanes Laura and Delta passed through.

Checking the meter operation is a good tip. In this case I would guess the coach engine has been run less than 150 hours for 3.900 miles. My Miramar has about 320 engine hours for 12K miles. You should be able to check your engine run time via the dash "Info" display. Turn ignition on , no start. Push "Info" button repeatedly to toggle through the different displays, one should show engine hours. (Your Axis may be a little different)

In a hot climate, like southern Cal, it would not be uncommon to run the generator 12-24 hours a day when driving and camping without hookups. At 12 hours a day 753 hours is 63 days of camping in the 1-2 years the coach has been in service. The size of your coach lends itself to boondocking. Many special interest events like dog/cat shows, races of all kinds, air shows, rock hounding, etc, etc.


I would be ok i the generator starts easily, runs smoothly under load with no surging, is relatively clean with no oil leaks, does not smoke when running.


If properly maintained and runs well, 753 hours would not concern me.

Just as a point of interest we used to put 50 or 60 hours a week on the generator when we were racing cars. We would start the generator Friday morning before leaving and not turn it off until getting home on Sunday. It was easy to put 600+ hours a year on the generator and as stated they will go 10,000 hours with regular service. Recommended oil change intervals are 100 hours but if you aren't in a dusty area you can go 250 hours with no reduction in service life.

I have 25,000 miles on my 2017 Axis and 208 hours on the generator.

You know that the last digit is 10ths of an hour ?

Ours had a little over 12000 hrs before loosing a bearing on the generator but motor never gave us a problem

[RKins]

Mine has 2250 hours on it. I have put maybe 100 hours on it since we bought the coach in 2016. We run it when driving down the road to keep the inside of the coach cool.

Good point TB

In da sowth,

if we are in it during the summer, the genny is running while not on shore power.


MOST of the time, these workhorses are just idling...

[Wildwoods22]

My first glance made me think 75 hours. But it's 753.6

[super_rep]

We have 133,000 miles on the coach and 3400+ hours on the generator. We hardly ever move the coach without starting the generator. The generator and roof ACs do a better job keep the coach cool than the dash air, plus the fact that it uses less fuel than running the engine AC.

We also race cars and enjoy race events. The venues do not offer hook ups in most cases, so the generator runs so 40 or 50 hours in a long weekend is not uncommon. I also used to manage a fleet of bloodmobiles for a local blood service. Each bloodmobile had two generators and would run for normally 8 hours a day and between 5 to 7 days a week. Most of those units were retired with the original generators still in service. We kept the oil changes up and maintenance up and they ran and ran thousands of hours with out fail.

My personal generator tech says NOT using a generator is the worst thing for them. They are built to be used, USE 'EM!

Keep in mind there is a world of difference between a splash lubricated Onan QG4000 that runs at 3600 rpms compared to an Onan QD 8000 diesel generator with pressurized oil system that runs as 1800 rpms.

Our coach has 36K miles and 1,150hrs. on our Onan gas generator. Just remember there are two different maintenance schedules for a gas generator. Every 100hrs. and every 500hrs.

True but people are reporting over 10k hours on a splash lube Onan. I guess the easy tell is anything without an oil filter is splash lubed. Never thought about it in that detail. My home generac has a filter, but it’s propane and 15kw.
