Great product. Everything fits on my generator. Will again buy next year

This product worked at intended. Happy with it.

Reasonable price and includes everything! Way cheaper than having it serviced and I know the job was done well

Everything was very easy to install and made for my Generac 24KW It been about 3 weeks since I installed the maintenance kit and have had no problems. The system is 3 years old runs perfectly. The maintenance schedule is based on hours run I believe I have about 40 hours on the system which is an indication of low power outages. I do the maintenance annually just because I do not want any problems. This is my fourth Generac over 25 years as I move frequently and do not want my family to be burdened with power outages.

As you would expect it to come.

I liked the price but the oil should be includedm

I decided to do this myself for the first time. I have a Generac Guardian Series 22KW 999 cc Engine, Model No. GOO70422. So 7042 in the list below.If the first 4 numbers of your Generator's model number begins with: 6055, 6098, 6103, 6244, 6250, 6258, 6551, 6279, 7034,7035,7036, 7037, 7038, 7039, 7040, 7041, 7042, 7043, 7045, 7048, 7049, 7077, 7078, 7141, 7142, 7145, 7146, 7163, 7173, 7174, 7175, 7176, 7177, 7178, 7189, 7209, 7210, 7218, 7219, 7291 then this is the right kit for you!This kit consists of:1 Oil Filter part no.: 070185E1 Air Filter part no.: OJ84782 Spark Plugs part no.: RC12YC (which is the Champion equivalent of Generac part no.: OGO767A)I recommend doing the Spark Plugs and Air Filter before you do the oil change since the motor doesn’t need to be hot for that part of the job and is more comfortable to work on cool. Especially in the Summer!Spark Plugs: The Champion RC12YC spark plugs come pre-gapped from the factory at .38 so you’ll need to widen the gap slightly to get it to .40 as recommended by Generac. If you are using a ramp style plug gap gauge you will want the center of the electrode to be centered on the .40 line on the gauge. You’ll need a 5/8 Spark Plug socket and a Torque Wrench. Plugs should be torqued to 25 Newton Meters.Note: I needed only the wrench and socket to remove the plugs. I did not need any flexible extensions as some did. Flexible Extensions can cause the Torque wrench to get inaccurate readings so I would not recommend using one.Air Filter: The Air Filter housing has one clip that flips up from underneath the front lip. There are two tabs on the backside that stick through two square shaped openings on the back and you’ll need to pull backwards on the housing until they pop through the square shaped openings, thus releasing the housing. The rubber hose simply slips off the hard plastic connector it is connected to.Oil Change: Run the motor (push the “manual” button) for about 5 minutes or so until warm and then push “Stop” to shut it down. Unscrew the cap from the flexible drain tube, and drain the oil into a container that you can later take to the auto parts store for recycling. I used a disposable Tupperware container and then transferred the dirty oil to an empty Orange Juice bottle with a screw cap. I put the old oil Filter in a ziplock baggie.Next, replace the Oil Filter. This is the messiest part of the job. I highly recommend unscrewing it by hand with several layers of paper towels under the filter and surrounding the entire filter itself as you unscrew it (lefty loosey). Put some clean oil on the rubber gasket of the new one and hand tighten until gasket touches and then tighten an additional 3/4 turn. Add 1.9 quarts of oil.Note: .9 quarts will leave approximately 3.2 ounces of oil in the bottle (Mobil One Oil has ounce markings right on the bottle). The oil dipstick has 2 holes in it. The oil level should be just above the upper hole in the dipstick (the oil is difficult to see but If you hold the dipstick at a slight angle to the light it’s easier). When full, replace the drain hose cap and put it back in the holder.Manually start the Generator and check for leaks. Lastly put the Generator back into “Auto” mode et Voila! You’re done for another 2 years!Note: You really only HAVE to change the Plugs and Air Filter every 4 years (they are schedule B items) but it’s so cheap and easy to do I do it every two years along with the other Schedule A items just for the sake of overkill. I enjoy overkill in case you haven’t noticed. 😉☝️This job was MUCH easier than I expected and in my case it saved me $350.00 (I live in California) and the hassle of having to be home to meet a Technician.Take your time and enjoy the process. There’s no better feeling than doing something for yourself and it’s nice to save a few bucks too! Good luck! 😎

Good service kit at a good price

My 22kw Generac generator ran two weeks straight during major hurricane power outage.A spark plug socket wrench, and a filter wrench and amsoil synthetic oil (Avoid mobil1 synthetic)is all that is needed to keep it running and supplying power for the whole outage.Powering my home a/c and all critical refrigeration, yes the unit ran wide open for the duration of the outage.I serviced the unit every 4 days (need it or not - which it did)I keep no less this than 6 of these kits on hand, Plus a quality auto battery(charged) as the stock battery (sucks) It is to small for the genset ahead of the next hurricane.As most auto part stores for supplies are not available during the outage.My reason... I would not let my personal truck run wide open for two weeks, the same reason applies to the generator.Yes the genset ran perfectly and wide open during the extended power outage.In my case failure was not an option, (HAPPY WIFE, HAPPY LIFE)!Without these kits = your DONE, calling your Generac service provider puts you in the que with hundreds of other guys with a damaged or ruined engine, and no power and lost refrigeration an EXPENSIVE ERROR.Living on the gulf coast is great, hurricanes are a naturally savage experience, be ready or be in the que.So choose wisely

Purchased several times, never disappoints. Price does fluctuate so keep an eye on random discounts if you purchase this regularly.

This maint. kit was correct for the 20kw generator. Kit included:Air filter # 0J8478Oil filter # 070185ESpark plugs - Champion RC12YCThank you Amazon.If any of you generac owners have ever had warranty issues or needed to contact generac customer service for these parts or anything else, you already know it is like pulling teeth, not one but many teeth!

Let you do the winter maintenance on a Generac 20KW backup generator in about 30 minutes. Great cost savings vs having a tech come in. If you can change the filter and oil on your car then you are capable of using this kit!
