I am a ASE master tech with over 40 years. You do fine work and pay attention to the details. I have seen some real hack jobs on TH-cam with so-called Generator Techs. Keep up the excellent work👍
Just picked up an old Generac model 044563 from caretaker. No start issue. Going thru it slowly. Little things needed fixing. Noticed a little oil by air filter housing. Your video's are spot on.
I have a 60 KW Katolite on a lab building. It's powered with a 350 GM V-8. Runs on natural gas. The only problem it has had in 14 years is the oil pressure sensor. The engine would come up to running pressure and stay there but the sensor would slowly drop down the reading until the control panel would shut down the engine. Other than that and changing the plugs once a year, it's done a great job.
Those are four pole rotors versus two pole. They run at 1600 RPM versus 3200. That makes them quieter and last longer. That's a total different kind of generator than these lawn mower standby generators 😁
Good stuff, I’ve had my Generac for about 15 years and she’s always been pretty good until recently, you gave me a couple good places to start. I do all my own mechanical and electrical at my house so I’m not an amateur but Not a generator expert. Thanks for the great info
I have this exact generator (model 0052541 16kw LP). Owned it since 2009. I believe it was new in 2006. I bought it from a generac dealer second hand in Redding, CA who was leaving the area. It will start with low-voc carb cleaner in the intake, but will not start on it's own. It has been a PIA forever. I replaced the main regulator assembly in 2019 from zillerelectric and it still won't startup on it's own without carb cleaner sprayed into the intake. I think the solenoid coil that sits in between the regulator might be the problem, it does get 12v to the coil (e.g. #14 wire). The valves are adjusted properly (.003), new RC14YRC plugs set to .040. I was trying to see which hose the LP uses from the regulator side to the carb intake, on mine it's the hose that is connected to " IN 2" which is closest to the edge of the side of the unit and sits on the right hand side when looking at the battery. "IN 1" goes to the NG side on mine and I am concerned it might be backwards as this unit has never worked right, even w/ the switch on the carb set to LP. I would guess this generator does not even have 20 hours on it as everything under the valve covers looks brand new. Oil was changed w/ synthetic a few years ago. Any suggestions would be appreciated. I have hired generac techs to come out and do an evaluation and they recommended the regulator swap-out, but that did not solve the problem and I ended up with hundreds of dollars in service calls without resolution. The propane company was here 2 days ago and they checked the regulator from the tank to be about 13.5 wc which feeds my unit. 10 years ago it was set to about 11 wc and had the same problems. Unfortunately this is the only unit which will run my 5HP well pump when power is out during public safety power shutoffs w/ PG&E and I don't care to spend $6k for a new one.
Great video brother. Generac teck from the nor west myself. A good t/s trick for a those older gens with that style air box and intake man. Is if it's running on lpv, hard starting and your out of ideas, flip the fuel selector to ng. If it fires right off, could have bad rubber gaskets @ the air box around the intake man.. took me awhile to figure that out , so I'm telling everyone I meet... keep safe keep warm.
They have gotten better since I started working on them in 2006 but there is a reason why they are more affordable and are sold to anybody at big box retailers. Thanks for checking it out, hopefully it will get warmer so I'll have better things to record.
They are a lot better than the first and second generation. Install is important, hopefully the installation company has a good reputation, the install is just as important as the equipment. Generac sells to every Tom Dick n Harry unfortunately.
@@HVACRSurvival the installer is a local electrician who has installed several units of various size over the past years. I have confidence in him; but bottom line is still the quality of the product.
I need to replace my oil cooler hoses. What are the specs or size of the hose? I see the part # as Genetrac 0C9806, 3/8" ID x 6" long, rated for 300 deg F. Are those the correct specs? Can I just get any oil cooler hose at any autoparts store?
Good morning great videos question I’m about to pick up a Generac serial number 4484389 please any pros and cons it’s used for my friend but it works thanks for your time
Will a worn/defective LP gas regulator create a situation where my Generac 04456-0 starts occasionally but for the most part won't start? I see in this video you refer to problems with the early Generac of which mine is one? Also any suggestion for a replacement regulator that won't duplicate this problem?
when you are referring to a regulator, are you talking about the lp regulator provided by the propane company or are you talking about the fuel regulator inside the generator? The one inside the generator is what I had problems with the most. The rubber tends to harden in the regulator and not react like it should.
@@HVACRSurvival The regulator inside the generator. The replacement I'm looking at has an additional port below the two main outlets that isn't there on the original. Can that port just be closed? Also any suggestions on how to remove cover from older Generac Guardian 12kw. Need to replace starter on this unit as well. Thanks very much for the response. Greatly appreciated.
I don't remove the cover to change the starter, I assume you must be a homeowner so make sure you unhook that negative wire from the battery or you will have a bad day if you short that thing to ground because that starter is constantly positive straight to the battery. Far as a regulator, be certain that it's the correct one, they may look the same but they are not all the same. I don't have access to the generator website like I used to so it would have to be looked up by either their parts department or maybe you could find something online.
Thanks Jack, I'm not doing allot of generators anymore and I never have been a gear head. Motors have never been of interest to me, so I'm far from a genius on motors, luckily I have family that are big into motors to lean on when I have problems.
This is a guardian series, uses an analog PCB, manufactured late ninedys early thousands, dis cont 2006, when they went to what they called " pre nexus"
pretty sure champion is the OEM plug manufacture, surely there's cross references online. I'd not hesitate to run Champions/NKG/Denso/motorcraft in place of them, just make sure you'r not buying counterfeit online and hope the parts houses aren't either :)
Champion for some reason is the brand they use on there motors. Generac truly designs and manufacturer's the motor. The larger Genrac generators have Ford, GM, etc. motors and they have whatever brand spark plugs they recommend. I'm not a gear head so I don't have time or the desire to cross reference the plug but because I have tried to buy them locally before from Auto Zone, Advanced Audio and Napa... I have found its a weird plug to match up. It can be done but it's odd and I believe NKG or Bosch might have been the few that crossed over but that was over 6 years ago since I looked...That's why I feel the way I do about it. My drive to do generators has gone way down because I'm not doing enough anymore compared to my prior employer so my thought is get in or get out but don't straddle the middle. (No body else wants to do them or learn them.) Think of it like a auto mechanic repairing a cars computer at the component level... The computer runs the car but that doesn't mean the mechanic is a electronic repair tech, so generally the mechanic has no interest in knowing why the flux capacitor is under 2.4 gigga Watts by 4.876% causing a random window to roll down every 47.8 days 🤣
Surprised you don't carry those step less clamps with all the other stuff you work on. Do you have an opinion on a better designed generator than a Generac in that residential range? Really enjoy your videos I share them all the time Thanks👊
I have a PEX stainless crimp ring tool but didn't have any of the small clamps. I use to run plumbing and electrical residential service in addition to all the stuff I do now. Most HVAC company around me have to do it all. I think Generac is a lot better now. I like Kohler but I'm not really experienced in them. I don't care for the Briggs n Stratton gen sets.
Man , you guys are really versatile , that's a job for an electrician innit ? Btw I see the mighty M12 is back , did Milwaukee do the right thing and replaced it then ? Cheers 👍
Yep, Milwaukee didn't have parts to fix it so they sent a new one. Around here electricians might know the codes and how to install it but not many want to learn to repair a generator.
I'm not a engine mechanic per say, I'm mainly required to change magneto's, adjust valves, change starters, chokes and safety switches. I do my work on site in the weather. So I haven't tried doing any bench testing.
when air cleaner is dirty or plugged... it will cause oil to be sucked up into air box through the crankcase breather hose .. found this problem many times.. change air filter your go to go..
None of these generators run long enough to even get the filter dirty. Most of them usually have anywhere from 40 hours to 150 hours or less. Thanks for the feedback and for watching 👍👍
Hello friend 😊 🌾 got problem 😭 1 - first name : generac 2 - last name : model number 00524440 16000 watts problem won't catch does not get fuel ( N gas ) problem may be out side regultor or inside regulator SOS = How can i check it out . battery = serviced oil = fresh spark plug ok start start = does not get fuel what should i do ? i call repair man but when i explained , they only looking for a mf stupid one can BF . why ?
Best thing to do is go on generac's website and search for dealers, look for the dealer that has the most certifications, then Google them and look for reviews. Unfortunately not everyone's created equal. Some don't care some don't know but it's unfortunately a fact of life. If you were close by me in Ohio I'd see if I could look at it but unfortunately I doubt you are.

Basically not pulling the fuel from the fuel regulator as strongly as it should?
No, air leak at the air box throws off the mixture, if you put it in ng it allows more fuel in...
Does the fact it's running on LP gas make it hard to start?
It seems to have a long cranking time compared to a gasoline unit.
Depends on how in tune they are. I have some that start fast but some of the older ones have some issues.
Nice job! I’m not a fan of generac generators at all, thanks for the video!

What's wrong with generac and what brands would you recommend
Nice work! I never see an HVACR technician work on a backup generator!
The electricians usually have a hard time with them around my area 🤣.
You got your impact back
Yep got it last week. Brand new because parts were not available.
great job all rounder
Thanks for watching 👍👍
GREAT INFO TX...IF ONE HAS 30PSI ONLY COMPRESSION ON A 9KW GENERAC GENERATOR..168 HOURS 3YEARS OLD ...CAN IT REPAIR OR NOT REALLY
Check your valve adjustment. if its ok then you would have to tear the engine down and replace the rings and whatever else is worn.
Just ordered the installation of a new Generac 17. Am I making a mistake? Has Generac corrected some of the issues you encounter?
They are a lot better than the first and second generation. Install is important, hopefully the installation company has a good reputation, the install is just as important as the equipment. Generac sells to every Tom Dick n Harry unfortunately.

Yes you can get the hose at the parts store. Tell them you want something that can handle oil. Use a regular clamp.
