Hey Jim,

Saw a method the other day that may help...

Get a nut that you could put over the old bolt and then weld it to the bolt through the hole. Wait for it to cool and Bob's your uncle... Well hopefully.

good luck.
Jason.

Thanks for the tip Jason, Sounds good I only have access to an arc welder I think a mig would be better.

Hi Jim, A possible solution, if you have enough room to work (you would probably have to remove the radiator) with a punch make a dent in the centre of the sheared bolt & drill about a 1/8" dia. x about 1/2" deep hole in the centre of the bolt. Then get a No. 2 or No. 3 "Ezy Out" You can buy them individualy or in a set from tool or auto shops. Good Luck  Wink

Question - did the bolt shear off after it had been tightened down onto the pump or was the thread really tight and the bolt sheared off before it bore down on the pump.
This is important as it determines how tight the remaining section of bolt in the block will be.
If a) then a simple drill and easy-out will remove it quite quickly as the remains should not be tight in the block.
If b) then an easy-out will struggle and may even break itself.  Welding a nut is the best solution.  Mig is best but a good arc weld will work - drill the nut with a countersink to enable good weld penetration.

Thanks Guys
I thought the ezy out would be the best solution. I will go and get a set of them tommorrow as I think this is the first of many to come.

I will use the welding as my second option.

Thanks again.  Grin Angry Embarrassed

Afternoon All
Thanks for the advice. Ken it was 1, I could have used a little super glue on a stick to get it out. I used the ezy out method it came out very very ezzy.

I have the whole set now so can shear as many bolts as I like.

By the way I replaced the bolts with 4 new ones thought after the first mishap it would be a good idea.

Thanks again  Grin Grin Grin Grin

Hey Jim,
A good set of taps is what you need next as you are going to find many bolts that feel to tight, so run a tap through them first. I did this to every thread when I put my motor back together and boy it made life easier.

Too right Chris, especially the hinge to door threads and the threads down the trailing edge of front mudguards.

Hi Jim

Just my 2 cents worth.  When using the ezy outs, you have to be very careful not to snap one.  They are brittle and sometimes it is a little tempting to give them a little extra just in case the bolt comes loose.  If this happens, they are virtually (ie. completely) impossible to drill through - I'm saying this with clenched teeth  Grin Grin Grin

Just a note from an old fella, ezy outs are allwelland good, but what happened to left hand drill bits, they were the dogs nuts at getting out broken soft bolts and studs. Anything harder than 10.9, like allen headed bolts use Kobolt drill bits, Snap On make em, yes expenisve but worth it if you are heavy handed. just a tip, if your using taps, use cutting paste or pleanty of lube oil and a is the thread is really buggered, use a second cut before the plug. Cheers.
