Broken mower bolt.

[Woodworks]

Hmmm not sure how to sort this out. Bolt has sheared off leaving the end in the drive shaft but using an easy out will only push it further in as left hand thread.

 

How can I get the broken bit out?

 

Thanks

Do you reckon the other end is tight in there, or is it just a case of getting to it to make it turn? If you can centre drill it then banging in a long Torx driver can give you something turn. This is easier than a hex bar (Allen key).

Not tried drilling yet as don't want push in further but may well give that a go

The bolt is normally quite loose fit in the thread

Drilling with a standard drill may just whizz the bolt out anyway given it is a left hand thread

Ultimately, does it matter if it goes further in, so long as it is free turning and will come back out just as easily? If you can bottom it out then it will give you something to stop it turning, but actually if you can get a drill to it and push fairly hard then it may well be enough to stop it turning anyway. If it's fairly loose then you won't need a very big hole.

Will that aluminium flange pull off to give you better access ?

 

What caused the bolt to break ?

OK fess up time.

 

It's not a left hand thread. Got into my head is was but soon realised otherwise when it went in when drilling. Up side is an easy out has done the trick.

 

CJ yep the flange does pull off. Had the machine 6 years and never discovered this.

 

Putting it down to being a chilled Sunday and hope my brain engages again tomorrow.

 

As for the reason for it sheering I really dont know. It was just doing some basic lawn cutting but it has been known for it to get abused when a brush cutter would be more appropriate.

 

Anyway Job done with no more damage. Thanks

Check to see if you have bent the shaft if it broke while mowing ,it will rattle it self to pieces if it did not have a crank protection gitted .
