Generator Replacement

[Jsroberts6]

I'm needing to replace my Cummins Onan 5500 HGJAB-1038E generator in my Fleetwood Bounder Classic 34B. My question is, do I have to replace it with another 5500 HGJAB-1038E, or could I replace it with a 5500 HGJAB - 6755 for example? I've noticed there's a bunch of 5500 HGJAB - XXXX models. As long as it's a 5500 HGJAB, will it be an easy swap? Thanks in advanced for your help!

They are all built on the same platform, so physically they should be easy. I'm not even sure what the difference is between them. I think the remote plug for inside start is the same on all of them.

Do you use your generator a lot? How many hours on it? 5 grand is a lot of scratch. Are you sure it can't be repaired? Other than being heavy they are pretty easy to remove. Most are on a steel frame with 4 bolts. It took 3 of us to lift it out and get it on the bench but easy to work on once the outside cowling is off.

Colaw has a 5.5HGJAB-1038D. I'm not quite sure what the difference the E vs the D is. I think a lot of these model numbers just have to do with when they were manufactured, the ignition system and the control board. When I had mine out and worked on it I ordered parts for it without the last 4 digits

Depending on how much you use it, how old your coach is, most of the time when they have used generators they are relatively low hours. Went and picked one up for a friend that had 55 hours and was half the price of new.

Thanks amosnandy. Here's a little more history. The coach is going on 10 years old. I purchased it brand new, and have had issues with the generator off and on since the beginning. For example, if I drive in rain, it shuts off. If I sit in traffic (cold or warm weather), it shuts off. It struggled to keep 1 of the roof AC's running. On my last trip a couple weeks ago we ran into a storm and the generator turned off. I wasn't too worried. After the rain was over I tried to restart it and got an error fault 32. I got home and changed the oil, plugs, air filter and it still wouldn't start. I checked everything Cummins recommends so I called a professional. The repairman found that the stator/rotor needs replaced. He quoted it to be around $2,000 to $3,000. I'm finding brand new HGJAB - XXXX models going for $4,000. Since I've been having problems from the beginning, I'm more inclined to get brand new. The exact model I have goes closer to $5,000. That's why I'm asking if any HGJAB model would work. The repairman only said to make sure it's carbureted.
