Topic tags/keywords: jig resource question

Hello guys and gals. So, I have a lawnmower (used twice) and the bolt that held the blade broke off from about 1/4 inside the shaft. Thankfully the blade didn’t come flying at me. Can anyone guide me as to how I should go about getting the bolt out?
Thanks in advance.

I believe the best and safest thing to do would be to take the engine apart and replace the shaft, it isn’t a hard job, just time consuming.

If it’s a push mower set on some saw horses and clamp it to them. Then use a easy out extractor. If it a rider the same thing but remove the deck.

Thanks. Just the thought of taking it all apart and as you mentioned the time involved, is not worth $120.

diverlloyd, will the extractor go inside the hole? I suppose if I use a small one it will.

Yes they come with a drill bit that is the proper size most of the time. So you center punch the broken bolt and then drill it. Then use the easy out. The only issue is what grade of bolt was it and if it was left handed threads. I would assume it’s a low grade bolt so the easy out should work. Does the blade mounting tap have two pins for aligning the blade and keeping it from spinning if so you may have more issues then just a broken bolt. How did the bolt brake?

Probably made in china bolt. First time it just fell out with the bolt and all, second time it just broke off while I was mowing without hitting anything. It doesn’t have the plate nor did it come with a washer; walmart crap.

Yes Wally World is junk. Sound pretty returnable if you just purchased it and ran it twice. But if you keep it you may need to put a good quality lock washer on it and/or some red loc tite.

mahdee, may I suggest you replace it with a Honda. I bought one in the early 90’s. I’m going to fire it up again tomorrow. It’s kinda like that pink rabbit with the bass drum on TV. It just keeps on running. After all these years I’m pretty sure I’ve gotten my money’s worth out of it.

You’ve used it twice, and there’s no warranty?

Thanks a million guys. I am certainly going to look for a Honda Bob. diverlloyd, Thanks for all the instructions. Rich, I used it once last year and then this spring. I think they have a 90 days warranty. I have a riding one and two push ones; to maintain about 8 acres.

If you go the easy out route, drill the hole with a left handed drill bit. That can sometimes get the bolt to back out.

I second the Honda engine and a older Briggs. I got 12 years out of the last Briggs.

a Honda would be a nice one. some Honda lawn mowers are made in the next county. their property has 5 or 6 acres of lawn grass. almost every time I drive past, there is someone riding or pushing a mower for endurance testing.
