djordje 0 Posted August 22, 2007 I just acquired my first simplicity and it is the Powermax 4041. She's a beauty that looks like it was indoors all of it's life, but a few dings here and there. As with any piece of equipment 34 years old, I will do a frame up restoration and would like to rebuild the the complete engine. Where do I find new oem pistons, rings, valves, for the Onan cckb? Thank you, Alex Share this post Link to post Share on other sites

djordje 0 Posted August 22, 2007 19.5 hp. I'm picking this thing up friday, but I'll have to do a compression check and look for leaks if I can get it started. Maybe parts are premature. Share this post Link to post Share on other sites
JP 0 Posted August 22, 2007 I meant pistons/rings....... LOL You should do the new tractor thing, go through it tip to toe, See what it needs. I find the biggest challenge with these (or ANY) tractor is to get the maintenance up to snuff! Let us know what you find! JP Share this post Link to post Share on other sites
