BadRandy 4 #1 Posted March 5, 2022 Im working on a non work horse project that has a smoked P216. (Seriously only 150 hours on engine. Previous owners pulled air cleaner off and let it set for years to fill up with rain water) I don't have time to do full rebuild....but have found a good running P220. Just curious if anyone knows if the physical bodies and output shafts of the P series motors are the same and all HP differences were based upon bore and stroke. 1 Share this post Link to post Share on other sites
kpinnc 14,627 #2 Posted March 5, 2022 (edited) I can't guarantee the output shaft is the same, because Onan engines were used by dozens of different brands. Wheel Horse used Onan engines with 1.125 OD output shaft size. Length would have been around 3.25 or slightly more. But everything else external will be the same dimensions for all three engines. Internally, the 216 and 218 are nearly identical as well. 220 has only minor differences. Edited March 5, 2022 by kpinnc 2 Share this post Link to post Share on other sites

You think as a motor manufacturer thry would have said here's our engine you make your stuff fit. Im gonna start measuring up what my 216 has and hopefully its a match 2 Share this post Link to post Share on other sites

BadRandy 4 #7 Posted March 9, 2022 Do you guys happen to know if the oil pans on these things are cast steel, cast Aluminum, or just pot metal? Just noticed on of the mounting feet is cracked. Looking at options to repair it Share this post Link to post Share on other sites

I have a really good fab guy right around the corner. Guess its time to trade beer for labor again. 1 Share this post Link to post Share on other sites
