I ordered a 70cc kit and new crankshaft seals /gasket kit. A good thing too. The piston skirt and one compression ring was scuffed pretty good, the cylinder was not damaged.
1.I started to take off the ignition/charging coils and need to know how to get the wiring harness out of the engine half? The rubber plug does not want to go backwards into the right housing. 2. Do I need to separate the engine half in order to remove the wires and the crankshaft seal ? If so,how hard is it to get the right side casing off of the right crankshaft bearing? Please help.
I used a two jar gear puller and a small plastic hammer. There is enough flashing on the cast engine half to grab the jaws of the puller. As soon as I felt tension on the puller I started tapping the housing with the hammer.You could hear popping as the housing was slipping off of the bearing. After 3/4" of movement,the housing was free. The seal fell off of the shaft bu itself and was well worn out. The crank shaft is VERY soft. I do not recommend trying to pick the seal out of the housing. Same goes for the aluminum housing. Too soft for any tools to be digging around. I tried to use postimage but it will not show the selected image,sorry.
