Generac 6840 – Frequently Asked Questions

1) Can I buy just one Generac 6840 maintenance kit?
No. The 6840 kit sells in quantities of 4 only, so the smallest order is four kits. For a property manager or MRO buyer running several generators across a site, that works out to a service round for four units, or roughly two years of servicing on two machines.
2) Does the Generac 6840 kit include an oil filter?
No oil filter is in the 6840 kit. It covers oil, air filters, spark plug, fuel stabilizer, funnel and a shop towel. If your engine takes a spin-on oil filter, order that separately, because servicing it isn't covered by this box.
3) Do I need any tools that aren't in the Generac 6840 kit?
Yes. There's no spark plug wrench or socket key in the 6840 kit, so bring your own plug socket. You also need a drain pan, since only the pour funnel is supplied. Everything consumable for the service (oil, filters, plug, stabilizer) is in the box.
4) What weight of oil is in the Generac 6840 tune-up kit?
A full quart of SAE-30 comes in the 6840 kit, which is the straight-weight oil Generac packs for these 389cc and 420cc engines. One quart per kit, one kit per service.
5) How many air filters and spark plugs are in one Generac 6840 kit?
Two air filters and one spark plug per 6840 kit. The extra air filter is useful on dusty jobsites where the filter clogs well before the next oil change, so you can swap the element mid-interval without opening a second kit.
6) Is the Generac 6840 kit a hazmat or restricted shipment because of the oil and fuel stabilizer?
No shipping restrictions apply to the 6840 kit, even though it contains a quart of SAE-30 and a half fluid ounce of fuel stabilizer. It ships as ordinary freight to a jobsite or a facility receiving dock.
7) What is the manufacturer part number for the Generac 389cc/420cc maintenance kit, and where is it made?
Generac part number 6840, made in the United States. That's the number to quote when standardizing a service parts list across a fleet of 5500 to 8000 watt Generac portables.
