Glad you guys are kicking this thing around. The owner bought the saw used. He has no idea whether these parts were aftermarket and neither do I. The input boot looks older, but that's hard to tell. The piston looks rather new and the exhaust side is unscathed. I have to wonder how long it takes a ruptured boot to generate enough heat to trigger snap ring failure. I suspect this happened rather rapidly and yes, the ring could have flown off on its own. I also noticed a worn crank seal but the bearings are still in fine shape.
The owner says he got his money's worth out of the saw. He used it on two or three tree removal jobs, so it lasted about 20 hours for him and ran like a bandit until the snap ring broke loose. He has no idea how long it had been run before he took possession, but the seller told him he had sent several tanks through it. In addition, if I rebuild it, I can keep it or sell it. Cosmetically, it was in rather good shape. Now it looks like an array of parts, like every clam shell 290 being rebuilt does and why nobody really enjoys rebuilding them. That includes me because it takes me four times as long to rebuild this beast than a Husky 350 or 353.
I really liked the forensic medicine post by TheTone. Kay Scarpetta could not have done better and neither could Maura Isles. Two thumbs up! But, the saw is not dead yet; I think I can resurrect it with a little luck, time, and skill.
