Product Description

Scheduled maintenance is a necessity for all standby generators. The Air Cooled Scheduled Maintenance kits offer all the hardware necessary to perform a complete maintenance on Generac air-cooled generators. Maintenance is recommended at every 200 hours or 2 years. If running in a dusty environment, more frequent maintenance may be required. Further maintenance details can be found in the generator owner's manual.

This kit was exactly what I needed for my Generac 17KW standby generator maintenance. I was a concerned when I ordered because your picture only showed one (1) sparkplug when two (2) are required. To my relief, the kit does contain TWO sparkplugs. Your description should specify (2) sparkplugs and show (2) sparkplugs in the picture. The kit is excellent, including complete instructions and even a paper funnel to use in pouring in the new oil.

For all who keep saying the plugs are wrong, please note:

NOTE: GENERAC HAS REVISED THEIR RECOMMENDATIONS FOR SOME ENGINES TO DIFFERENT SPARK PLUGS FROM THE ORIGINAL! HERE IT IS:

OHVI 990 INDUSTRIAL ENGINE ORDER 0E6037.

990 or 760 ENGINES USED ON HOME STANDBY, RV, AND PORTABLE, ORDER 0E7585A (Champion RC14YC - Pre-gapped at approx. 0.040")

RVs WITH 220 THROUGH 570 ENGINES ORDER 0G0767A ((Champion RC12YC - Pre-gapped at approx. 0.040") ~~ EXCEPT RV MODEL 4700 WITH A 220 ENGINE ORDER 0E7585A.

PORTABLES WITH ENGINES 220 THROUGH 410, AND 7KW HOME STANDBY: ORDER 0E7585 (Champion RC14YC - Pre-gapped at approx. 0.030")

PLEASE CHECK YOUR MANUAL for the correct SPARK PLUG GAP for your application!

The engine numbers shown above refer to the size in ccs. Example: 220 = GN220 or GH220, 990 = GT990, GTV990

I called Generac customer svc. this morning and notified them that the spark plugs included in the kit weren't correct for my 12KW model 04456 generator. They will be sending the proper plugs (RC12YC) and hopefully the company do a recall of the kit to replace the RC14YC4 plugs. Give them a call and be sure to replace those plugs if they aren't RC12YC or cross reference/comparable to another brand such as AC Delco 41-602, Autolite 3924 or Stens Se-12rcy.

Update - 2/10/2012
The plusgs sent were still RC14YC. I called the company and was told to gap them at .25 mm (.04 in.)and they would be okay.

This kit came with Champion RC14YC4 sparkplugs. The owners manual calls for Champion RC12Y sparkplugs. Regardless, everything else was perfect and I couldn't beat the price so I kept it.

This is a good deal. I should have purhcased two of them. I recommend the seller who sent the package out immediately. The kit includes the correct size air filter, a new spark plug and new oil filter. It even includes a disposable funnel and a spark plug wrench. I recommend buying two or more. They should have a long shelf life and you know your generator will need the oil changed again and again and again.Generac 5664 Maintenance Kit for 12 - 18 kW, 760/990cc Engine

This is a perfect kit for the Generac generator at a great price. It is very easy to change the components. The only thing you need to buy separately is oil. I bought a couple of extra kits to put in storage. Five stars!

This is a great little package for maintaining your generator. Includes everything but the oil. You can buy the parts separately at an auto store but it adds up to more money. This is a good value.
