View Full Version : Hit a chunk of steel with my 21" honda. What did i break?

I was using one of my 21" Honda HXR217TDA. I hit a large piece of steel and the machine jumped. I shut it off immediatly, but when I went to restart it, it vibrated likle crazy. So, i shut it down and used a differant mower.
I came home and pulled the blades off, they were damaged pretty bad, but i tried to start it with the blades off and it would not start.

Do you think i cutthe key? Or did i bend the crank?

You bent your crank.

Get a brand new blade and put it on, you probably just bent it, and it won't start without a blade because it's also your flywheel heh. Do that, then if it doesn't work we can troubleshoot further.

The honda push mowers wont start with the blade removed. Buy a new blade, put it on and you should be good. The blade is belt drive so you may not have bent the spindle shaft.

The blade is not belt drive!

Put on a new blade, unplug the sparkplug, when mower is on the side turn blade around. Does the new blade line up in the same spot from one side of the blade to the other? If its lower on one side than the other your shaft is bent.

it's a 21" so it's not a belt driven blade... put a new blade on it and give it a try. if it starts and vibrates you bent the crankshaft. if it won't start you sheared the key and it's out of time now. either way it sounds like a you are going to have to tear into it.

Thanks guys. The crazy thing is...the new blades cost $40, and a new crankshat is $40. Go figure.

I have hit rebar with my P.O.S. Troybilt and it didn't bend anything! Looks like some of you guys SHOULD buy residential! :)

Funny you should say that. Our troybuilt with the kawi motor has hit metal twice and with such force it bent the blade like a pretzel, still no damage to the engine...:)

check prices on the blade. I can buy blades for my honda's and they are maybe 18 max. as for the crank shaft that is just that. then you need new seals and what not to get it back to running condition. I would buy a new blade and see what it does then start tearing apart the engine if it still vibrates. also check the key. it could be half sheared still turns but has a small wobble which would cause vibration.

if you can buy a crank for $40 i say snatch a few of them. all the ones for a honda i normally see priced are double and triple that and that's just for the part, not labor.

If you can put in a crank yourself good for you $100, if not $300 to $400 bad for you. P.S. Its a bent crank.

You probably bent the crankshaft. If it is not vibrating to badly, you might be able to get away with running it till it dies. Check your bottom oil seal and make sure its not damaged. You might also consider putting some locktight on the oil seal to help to keep it in place despite the vibration.

I Bent The Crank On My 21 Honda Harmony Twice (2 Differant Mowers) And Was Able To Straighten It Out (fairly Well) With A Couple Of Good Wacks Of A Hammer. I Had This Situation Twice And Don't Know If I Just Got Luckly. It Still Ran With A Slight Vibration, But Good Enough To Work.

A single blade is 40 bucks for a walk behind? Dang im glad i still got old john deeres its like 11 bucks for a blade but 40 bucks for a crank aint bad i bent a crank on one of mine and a JD crank was going to be around 140 bucks so i offered the dealer 50 bucks for an engine on an old jd with a blown transmission and its running great still to this day
