broke my fiance's lawn mower..is it fixable?
While I was mowing, I got too close to this metal thing sticking up in our yard by our cement curbing, and I heard it hit the motor, it made a loud noise, and then the mower just shut off, and now it just won't turn on again, usually when I yank the cord thing, I can hear it try to kick on, and now it does nothing...he's going to be so mad at me. Can I fix this? I turned the lawn mower upside down to see if maybe part of this metal thing would have fallen off or whatever, and I didn't see anything. So what should I do? PLEASE HELP!!
if the blade just needs to be replaced, will i be able to just put a new one on there, if i can find step by step directions, or will it be too complicating for me to understand?
Also, is there a way to visually tell if it will just need a blade replacement or gear replacement?
Well.... It's like this see.....
Your not going to be able to tell fully what you did without taking it apart, so a visual check as it sits is out of the question.
The best case scenario is that you just damaged the blade, but that wouldn't affect the motor. Since the motor won't start now, we already can tell your beyond the best case scenario.
The next best case scenario is that you sheared the flywheel key, and the flywheel key (less than $3) did its job. It's VERY probable that the flywheel key is sheared, so you engine timing is out the window, but in all likely hood it doesn't stop there.
The worst case scenario, which is very probable, is that you also bent the crankshaft. This one you CAN visually check. Disconnect the spark plug and turn the unit on its side, carburetor up. With the unit on its side, pull the engine over, keeping an eye on the blade bolt. If the bolt wobbles, then you have indeed bent the crankshaft. If you have bent the crankshaft, then it becomes a question of how good is the lawnmower. If the mower brand new was less than $150 than your probably better off buying a new one. If its a nice $300 or more mower, then repair is the better option. A new crankshaft will run between $50 and $80 dollars, about $10 in seals and gaskets plus about $75 in labor (roughly)
