Not being a smart A be paitent you can get em in. I use a small drift pin inserted in the other side of piston pressing against the wrist pin to help keep them in place.
Shep
Good advice and thanks. Were this a wristpin that could be pushed in with a finger, it would have been a snap. Both the old/new wristpin had to be tapped in and out with a hammer or a "c" clamp. I believe Echo uses very tight tolerances. I ended up using both wristpins inserted into the piston enough to hold the washers,then slid the piston over the connecting rod and tapped it through and pushed the old wristpin out the other side. I like your idea about the small drift pin. that would effectively do the same thing.
WSE, I ended up turning the saw on its side and that works better. With your comment about pushing the wristpin through with your finger, I believe I will take very fine sandpaper and smooth up the inside of the piston bosses next time if the wristpin is that tight. Thanks for your help.
The new piston w/ washers is in and the cleaned up jug is on. Waiting on the new collar that drives the oiler worm and the saw will be ready to finish assembly and fire it up.
Should get a 600P on Wednesday with a toasted top end and I will get to have all this fun again. It wont be as frustrating this time.
WSE, if you have a 600P piston kit in your shop, would you send me a PM ? Thanks
