dmill_theredneck 1 #1 Posted February 18, 2018 Was wondering if anyone knows of a place to get parts for on an engines, I need some internal parts, rings and valve baffle spring. Mines blowing oil out of the breather. Or does anyone have a motor laying around for parts. Thanks Share this post Link to post Share on other sites

onanparts.com 178 #5 Posted February 18, 2018 Several different styles of rings were used, early and later style. Important to measure the original compression rings to determine the correct replacements. 5/64 early, part # 113-0314. 1/16 late, part # 113-0310. No mic or calipers handy? A nickel is close to 5/64 and a penny is close to 1/16. Check the fit in a piston groove with your pocket change. Parts get changed over the years so you can't always go by the book with Onan piston rings. Share this post Link to post Share on other sites
