Generator Installed on Incorrect Side

[leemccraw]

2015 Thor Hurricane Model 34F

I recently purchased the above unit used and with warmer weather began having problems with the generator shutting down because of over heating as per Rv repair dealer. The problem persisted and I took the unit to a cummins dealer who immediately recognized the generator had been installed by Thor on the wrong side of the coach. The generator is designed to be used only on the drivers side of the coach for proper air flow. Thor at first denied this occurred but later said this is a warranty issue and the warranty only applies for the first owner or one year.

Has anyone else had experience with this issue?

The gen set should not care as long as it gets proper air flow around it. Maybe something can moved a bit. Doesn't answer your warranty question but maybe a fix that doesn't dig to deep in your wallet.

Interesting. The Cummins/Onan installation instructions for my generator give clearance distance requirements but if I recall correctly, there is nothing, not a single word, that says the generator must be installed on the driver's side of the coach. I believe the Onan service center is blowing smoke up your a##.

Two things to check on one is they have a lot of bad fuel pumps on that generator. 2 Follow the gas line make sure that it is not kninked in any way and that the fittings are proper size they run hot and and it the lines are not flowing proper you will get the old fashion vapor lock

I do recall a problem with my ACE 29.2 a few years ago, I was having the same problem, only when the outside air temp was above approx 75-80 deg while driving down the highway, the Genny would shut down. On that particular model 29.2, the Genny was installed on the drivers side, behind the left front wheel. It was fairly close to the engine compartment.

After some research I learned that the gen was too close to the engine, as you drove down the road and heat was carried away from the engine compartment, that heat traveled right past the running gen, which would add to the heat already produced by the gen and create a hot zone, which would overheat the gen and it would shut down to protect itself from damage.

Thor had apparently come up with some type of heat shroud modification to increase the airflow and prevent the stagnation of heat in that area, I don't remember the specifics, you can do a search of these forums and find the thread. This was about 3-4 years ago!

It appears on the larger class A's, Thor has consistently put the Genny on the drivers side towards the rear of the coach, away from the coach engine, I haven't had the problem with the Miramar so far.

Hope this helps!

On our Infinity 34H the gennie was on the drivers side by the bedroom, only issues were that I insulated the gas line to the fuel pump & to the carb because it tended to vapor lock in 95+ heat also I had to extend the exhaust pipe 2" or the co2 alarm would shriek.... Then installed the Ven-Turi to run the exhaust up above the roof when camping. (not running down the road)
