BenTheWheelHorseMan 43 #1 Posted February 21, 2016 I just bought a Cub Cadet 104 with a starter generator and a free a few minutes of running the starter generator gets too hot to touch and it smokes out of a small hole near the back of the housing. I know this is the wheelhouse forum, but this is the only place I know. Also the engine runs super high rpms so that may not help the starter generator any. All feedback is appreciated.

pfrederi 18,360 #2 Posted February 21, 2016 I would first suspect the voltage regulator. Field coil contact in the regulator may be stuck making the generator output the maximum it can. What is voltage when running? Is there an amp meter can you wire one in ??? 1 Share this post Link to post Share on other sites
squonk 42,645 #3 Posted February 21, 2016 I would go with the regulator as the culprit as well. But if the Genny is getting hot and the Genie escaped out the small hole in the back, better plan on getting it overhauled. 1 Share this post Link to post Share on other sites

I will look into replacing the voltage regulator as well. Is it possible that the high rpms of the engine could cause it? I think I need to set the governor to slow it down.

pfrederi 18,360 #5 Posted February 21, 2016 RPMs very very doubtful. If teh regulator was working it would control the field (increase the resistance to ground of the field coil) so as to reduce the generators output Share this post Link to post Share on other sites

BenTheWheelHorseMan 43 #7 Posted February 22, 2016 Is it possible that the heat and smoke could have been cause by worn bearings? I have a friend that said he has one and replaced the bearings and it was fine. Still planning on a full rebuild but I wondered if that could be the problem.

Does it have oil points (spring loaded covers on the ends. put in some oil... not much just a few drops and see if it runs quieter. Again what is the voltage when it is running and can you check for amperage otherwise we are guessing Share this post Link to post Share on other sites

I have not done that to this point. Share this post Link to post Share on other sites
pfrederi 18,360 #10 Posted February 23, 2016 In addition to amperage check the voltage when running should be 13.6 to 14.5 or similar. 1 Share this post Link to post Share on other sites
stevasaurus 23,090 #11 Posted February 23, 2016 (edited) One thing to maybe be aware of with the Cub Cadet starter/generators...the Cubs use a "clockwise rotation" starter/generator. Might have CW stamped on the back end. Wheel Horses use the "counter-clockwise rotation" starter/generator...CCW. This may make a difference if you have to order parts. Sorry guys...I got it backwards. Cubs use the Counter-clock wise rotation. Wheel Horse uses the Clockwise rotation.

That is kind of what I was thinking as I was reading this, wonder if it is the proper S/G or if it may have been replaced with a CCW unit which is the most common type? 3 Share this post Link to post Share on other sites

Steve is usually right on and I followed his lead, @specialwheelhorse caught us all napping; Senior Moments are great. But, I remain curious as to this not being the correct rotation S/G on the Cub. 1 Share this post Link to post Share on other sites
stevasaurus 23,090 #17 Posted February 24, 2016 Richard, I was involved in a thread a few years ago, and I had to find it today , but you can change the rotation on a starter/generator by changing out the field coils. Let me post a link to that thread...if someone changed out the field coils, you may be OK. Might need SOI to come in and help to determine if that is what you got.
