oops! 122 bolt sheared off
 

Hi all,

Since I had the grill and hood off my 122 until I get the parts for my pto button repaired I thought I would take the heat shield cover off and clean it up and paint it. Well I ended up shearing off the rear bolt which Im assuming is one of the head bolts. So there is still part of the bolt in the hole and its the threaded part. :bash2: :angry:

:Spank:,

Can you post a few pics of what you have? All depends on what's exposed or is it flushed or recessed in the hole. That will determine what advice you get next.

you had to mess with it? you're probably going to want to take the head off now. hopefully it won't be broken off flush. those are grade 8 and hard to drill so you'll need really good drill bits and a variable speed drill if you have to do that

If its broken off clean with the top of the head (lucky for you), just pull the head and use a stud extractor to remove the rest after LOTS of soaking with penetrating oil over several days.

When I say stud extractor, I'm talking about this (or similar... I have a Snap-on set at my disposal that is a little different, but it's ancient and was $400 in the '80s... glad I didn't have to pay for it):

The cam type ("not this") won't give you as much surface area to grab and won't grab as well.

If you have to drill it out try to get some left hand bits ("reverse" twist), some good cutting oil, and hope it backs out as you drill. Take it slow and steady. The jury is still out on where to buy good left hand bits as all I've found are made in China... :( Drilling a broken drill sucks more than just about anything.

I have a Snap-On set of LH bits and easy-outs. Never found a better set yet!

Only thing worst than a broken drill bit, is a broken easy out or tap. They are harder than drill bits. :biggrin2: (Keep that in mind while your trying to get the bolt out.)

yea the snap on set is really good but kinda pricey, my dealer has the master set on sale this month for 100 off.

Anything Snap-On is "pricy" compared to most all tools. But I buy their stuff for good reason....... IT LASTS!! And doesn't very often fail/break. I used to break rachets regularly. Now if they need rebuilt once every few years I've used it pretty heavy!

There are only two bad things about Snap-on Tools. (A) Sucks when you loose them, and (B) sucks when they are stolen.:angry:

i hear that, 99% of my tools are snap on.
