Raider12 13 #1 Posted October 24, 2013 Does anyone know what a "complete" 20 hp Onan off of a 520H would weight? This engine has the exhaust, starter etc. I appreciate you in put. Share this post Link to post Share on other sites
Hodge71 663 #2 Posted October 24, 2013 Should be about 170 pounds maybe 5 or 10 pounds either way. I know its much, much lighter than the old Kohler twins. They were cast iron, the Onan is aluminum…. Share this post Link to post Share on other sites

I doubt it is even that heavy. I just took one off a 520H I parted out. If you need me to weigh it I can tomorrow on an old bathroom scale. Share this post Link to post Share on other sites
sorekiwi 761 #4 Posted October 24, 2013 I'm thinking its a lot less than 170 lbs. I've lifted a complete one onto the bench by myself, and I only weigh 170 ish. (and I wonder why I have a bad back and a double hernia... ) 2 Share this post Link to post Share on other sites
Hodge71 663 #5 Posted October 24, 2013 I stand corrected then Kiwi. I just did some comparing against a Kohler single I just shipped. That was 135 out of the crate and 153 in it. The last Onan I moved was a P216 and I thought it weighed more than the Kohler and the crate. I could very well be wrong as the Onan was moved last year, the Kohler was last week.

Kelly 1,028 #6 Posted October 24, 2013 If I was to guess I'd say about 125 I can pick them up and walk away with one, not far but still, and I think a single cyl. big block Kohler is a little heavier Share this post Link to post Share on other sites

Jake217 20 #8 Posted October 29, 2013 I've pulled a K341 thumper on my C-165 and the Onan P220g on my 520H; both for refurbs. I weigh about 170 lbs and I had no problem lifting the Onan off and back onto the frame. The Kohler seemed a lot heavier than the Onan. It was much more of a "waddle walk" carrying that Kohler that the Onan. Pulling the flywheel takes off a lot of wieght. Obviously moving them dry. Hope this helps Share this post Link to post Share on other sites
CRE1992 135 #9 Posted October 29, 2013 A complete onan engine should weigh only about 120lbs... Refer back to this thread when I weighed one... Share this post Link to post Share on other sites
boovuc 1,090 #10 Posted November 2, 2013 Ditto on the 120 lb. Using a very scientific bathroom scale................I weighed my P220 with muffler, PTO bell attached and tins included and I got just shy of 120 lbs. It might be a little heavier as this scale was a POS but my ex kept it around so she probably knew it weighed things a little under! 2 Share this post Link to post Share on other sites
AMC RULES 36,945 #11 Posted November 2, 2013 Every spec known to man in the Onan factory service manual... except the weight of the darn thing. Share this post Link to post Share on other sites
