The crankcase shaft shaft (15) seems to be broken because when I turn it, the piston does not appear to move up and down. I can not see how to remove the crankcase shaft to inspect it. Does item 43 push not need to be removed? If so, How?
Just warched your video and replaced the rope which broke on me this morning. Wound the recoil spring up put everything together then pulled the cord. Recoil spring went whirrrrrrrrrrrrrr. What did I do worng. Spring isn't broken.
The drive shaft pulley is simply threaded onto the drive shaft. But as I am sure you have found, it is not as simple as just unscrewing it from the shaft. When you try to unscrew the pulley the crankshaft just rotates so you can't unscrew the pulley. The trick is to bind up the piston so that the crankshaft can no longer rotate. To do this start by removing the spark plug. Now find a piece of small rope. An old shoelace works great. Take the rope and insert it through the spark plug hole into the cylinder. Be sure to leave enough of the rope out of the cylinder so that you can remove it later. Now that the piston is bound you can unscrew the pulley.
The belt on my edger broke. After replacing the belt, the blade will not turn. The shaft/spindle rotates with no blade attached. As soon as I attach the blade it will not turn even if I just hand tighten the bolt holding the blade. It seems as though something is binding the shaft from rotating.
I am having the same issue. I need to replace the starter cord, but the drive bit is five sided and I have tried to fiind the right tool without any luck. If I am looking at it correctly, the pulley is threaded. I need to know the bit size and where can it be purchased?
