Great video thanks for the information. I have owned a Predator 8750 for about 5 years that has less than 10 hours use, 6 of those hour just today. I wired it to run my house and while running I noticed different voltages on each leg of the 240 volt plug so my search began to learn how to troubleshoot and fix this issue. You mentioned in this video that if the generator was used to run your home neutrals needed to be unbounded. Please explain this or point me to the right information. I'm still trying to understand why a never used generator would have different voltages so the search continues.
I’ve broken off a long shank bolt doing this “push out” method before as well. A tip I’ve used since then is to rotate the stator/engine upwards slightly (15-20d) and fill that stator hole with water about 3/4 of the way. Then use a short screw with Teflon tape and give it the beans. I usually ditch the impact for this method but using this hydraulic technique makes life easier and I’ve never broken off a bolt inside the stator since. Nice video and channel.
Just bought a Predator 9000. Already had to work on it. The back cover had been Smashed on. It was bent badly. It cut into the wires running into the back. As soon as I started it, it started arching! Turned it off immediately! Like to never got the cover off! It was about 1/2 in on too far! That is what caused the wire to get cut. Fixed it, put the cover back on and now it is working great! And this was new out of the box!
Nice video. I have a Predator 9000 with 30 hrs on it. It overheated and melted the wiring in the stator. I can replace the stator and rotor based on your video, but finding the parts is proving difficult. Suggestions?
I just got a 6000w with a 13HP 420cc engine what do you recommend for a break in procedure? How long to run it with out load? and then like half load? before I give it all the beans?
I have a predator 4000 that only produces 4.8v AC on both legs. I've done all the tests, new avr, brushes, etc, resistance is with spec around 1 ohm both legs and 50-60 at the brushes. haven't pulled the head apart yet to inspect the windings, but what would you suspect the issue to be? this generator has 0 hours on it, bought it a few years ago, but then didn't try to use it up until recently, and found it to not be working.
What are the most common causes of small 2000 watt inverter gens that run but no power output. No idle up from computer. Just runs but doesn't put out.yamaha,or firman 2000
I just picked up a predator 4375 that was in a flood and totally submerged in muddy water. I took it apart and cleaned it all up the best I could and used a full can of electric parts cleaner on the power head, I changed the oil and gas and this thing is running great and making power. I cant hardly believe it lol. How long do you think it will last?
Hey there! I was wondering if you might be able to help. I have a predator generator that delays in making power. The engine runs fine, and once it kicks on, the power is good and consistent. It takes about 3-5 minutes for the power to come on after we start the engine. Any ideas?
Loss of residual magnetism. First try running it more frequently. It is a self excited gen it must either have residual magnetism or a pmg permant magnet gen rotor to produce field current. Residual is cheaper so most likely.
Where are you out of? What I have the Duramax 9000 inverter, and yesterday at camp, I turned camper ac on, and I lost all power. The generator is still running but has no output power. Generator turns on runs great, but 0.0 OUTPUT power. What went wrong? It's pretty new maybe 1 yr 6 months old
Question, i have a predator 8750 420cc that i bought with a blown engine. I rebuilt the engine to where it runs perfect, but figured out i have no power. I checked the wiring to see if they were color matched THEY WEREN'T. all colors were moved down one pole, the black was grounded, and the ground was connected to the red wire. I corrected the wiring and still no avail. Could there wiring messed up something?
I have the 9000/7250 manufactured Aug 2019, purchased in Mar 2020, has NEVER worked right, but did not know it until after their 90 day + extended warranty were both expired. The Black wire leg started tripping the breaker. HF is still jerking me around on a replacement breaker since they redesigned this model & their parts are all screwed up. Found identical breakers online, put one in, fired it up, had power on 1 120 outlet, but the other was dead, it ran for a bit then I heard a POP but didn't see any sparks or smoke, & shut it down. Engine still starts & runs great, but no power out at all. I may have crossed a connection between the harness from the powerhead to the wires on the engine end, because I hooked them up by color, not realizing they stupidly change wire colors on a lot of the connections in the back of the control panel where they are one color but as they enter the harness to come out to the engine end, they are no longer the same color! I have no idea what or where the POP came from, cannot see any burn or scorch marks anywhere inside the powerhead when I removed the cover to look. I am now clueless as to which parts to check, or how to even check them, and I can't find wiring diagrams for this model anyplace. ANY pointers from anyone! HELP!! I now own an expensive boat anchor instead of a generator!
@@theequipmeptguru9030 ok. That was the conclusion I leaning towards after all the electrical diagnostics that I did. Would you happen to know where I can get a stator/stator-rotor from that fits my unit? I found some, but I don't know if 5-6kw compatible with 8kw.
Hi , quick question, I have a duromax xp 4000 s that stops producing power with a 2 inch submersible pump, it pumps for a minute and stops producing power for like 30 seconds and then pumps for a minute strong and then doesn't fit 30 seconds, annoying when you're trying to keep up with water
@@danalmeida5380 FLA is a rating that should be printed on the motor, Full Load Amps. so 10.5A @ 115V is roughly 1200 watts, half the generators output. sounds like you have a faulty AVR on your hands
I’m not sure how you got that 14mm(12mm for yours) my motor keeps turning over backwards. I tried to shove a couple things to lock it up but had no success just keeps turning
@@theequipmeptguru9030 got it done was able to use a extension to lock into the metal fan blades, was also easier to use a deadblow hammer on the bottom mounts to shimmy the generator off as one piece. Luckily was able to use another generator assembly off an old one with a bad motor. I’ve now realized I need more generator parts😂
a lotta guys will wind a thin piece of rope or twine into the cylinder- stops the piston from reaching all the way to the top of the stroke, so it won't turn over,
I hope you don't mind getting some bit of critique... I don't profess to be better than you but, there are things that you can objectively tell whether it's been done right or wrong. Overall, you seem to have a rather heavy-handed approach on things; Dragging and throwing stuff around like tools and parts, and this seems to manifest in the quality of your work... First, you broke the bolt that would've dislodged the rotor, destroyed the end bearing when you forced the stator off with what looked like a crow bar, and then ultimately dropped the rotor on a hard surface. I mean, that rotor looked usable and only the stator needed replacing. If I was the customer, I would've been upset having to spend more for a replacement rotor. Anyway, when you were still trying to tighten the bolt to free the rotor, the end bell (and stator) was still attached. Further, the end bell was still on their rubber supports, limiting its movement and hence, destroyed the bearing when the stator and end bell were forced off at a weird angle. I also don't remember you using a torque wrench and just relied on the impact driver to tighten screws on soft aluminum. Finally, you didn't check the frequency/RPM nor address the surging behavior of the engine in the end. I can only hope that you take this positively. More power to you. 🙂
I have a predator generator & the circuit breaker popped so I tried to reset it and now it won’t reset. Or provide power Did my breaker go out or do I have to replace the outlets
If you tighten the alternator bolts without a torque wrench, it will loosen, and rub the rotor since all the bolts have a different pressure that will be accentuated by vibration ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bvjjrhhiOZo.html 11:34
⚠️Portable Generator Safety Tips: 1) KEEPING OTHERS SAFE: Please do not allow an unqualified person or your children to operate and service the portable generator. Just because some manuals don’t say that doesn’t mean it’s safe. That is important against the generator safety rules. We also need to be keeping an eye on our children too. You need to make sure that your children are not playing near the portable generator especially when it’s running so they won’t get electrocuted. Generators pose electrical risks and they can be hot during an operation. Please keep your children away from the portable generator at all times. It is important to keep our children safe especially our little ones. Be aware of all the hazards. 2) WHERE TO RUN YOUR GENERATOR: Some people use their portable generators indoors which increases the risk of carbon monoxide poisoning. It’s important to have carbon monoxide detectors if you have a gas generator. Never ever use your generator indoors even if your doors and windows are open and even in the garage is not safe to use a portable generator. Also please never use your generator in your deck or balcony. It is never safe to use your generator indoors and in enclosed areas of your home. Your generator needs to be 15-20 feet away from your house. 3)FIRE SAFETY: Never refuel your generator while it’s running. You need to let your generator cool off before refueling it and before storing your generator. Never overload your generator too. Never ever back feed your generator into a wall outlet. Also never store propane tanks indoors. Please keep flammable things away from the generator as well including cigarettes. Keep cigarettes away from portable generator. Having a fire extinguisher next to the generator is also important against the generator safety rules. It’s also not safe to move your generator while it’s running. 4) GENERATOR OPERATION: make sure your hands are dry before touching the generator. Never use your generator in wet conditions. Don’t let your generator get wet. You need a generator tent if you need to use your generator during wet weather. Please don’t wear loose clothes when operating the generator. Turn on your generator before plugging in appliances. Use the right cord for your generator. Please do not use worn out cords. It is always important to follow the safety rules when using a portable generator. Hope this helps. This is just a safety reminder.
