European and Other Bikes / 2V Jawa Speedway Engine Piston Seized
« on: March 16, 2015, 06:57:10 PM »
Hi All,
I have been asked if I could take a look at an old speedway engine or a guy who is restoring the bike. The engine is a ESO engine but the piston is seized solid in the bore and has been since the 1970s. The engine seized up and the rider took the engine out and replaced it and left it until now. I have tried parafin, Gizer and Gunk but to not avail. The barrel is lose but but obviously cannot be removed. I have tried a wooden block and hammer but have stopped after the blows were getting harder! Any suggestions greatly received. I have considered machining the piston away but was wondering if the is a non destructive method out there.
Thanks
Jon
