Default Generac GN410 vs GH410

Greetings. I've been looking high and low to find out the difference between the Generac GH and GN 410 engines. I am ordering parts for my generator and need to know if there is a difference. I own a B & S EXL800 model 030244-01 portable generator with a Generac OHVI engine model number 0052331, serial number 7946xxx displacing 407cc (but usually called a 410 cc). The label also gives a family name: 6GNXS.4072GA:EM. So far, according to manuals I've found on line, it appears to be a GH410, but I'm not sure, nor can I find if there is a difference with the GN410. Any wisdom will be edifying. Thank you.

Hi Med,

No personal experience with GN/GH410, but lots of experience with GN220.

All of them are referred to as "Generac/Nagano" engines. Designed in Nagano Japan and built in USA. Good engines, OHV with cast iron cylinder liners, full flow lube system with oil pump, filter, lop switch. The oil filter mount may be missing on some of the generators sold thru Sears. Easy to add back on.

Back in the 90's they were all "GN" engines. Briggs/Stratton bought portable genset division of Generac around 2000. Generac could only market home standby stuff for 10 years. Now they are back in the portable business.

Easy to identify by "OHVI" on rocker cover. Not just "OHV", those are Briggs or other supplier engines. Different beasts.

Somewhere thru all this the model designation changed to GH. As far as I can tell these are exactly the same as the GN engines. (not sure if the GH models are still built in Wisconsin). The parts use the same numbers. The long block is the same part number.

Jack's Small Engines has full parts blowups of both GN & GH and can supply most all. Sometimes need to order from the GH page if part isn't listed on GN page.
