Calling CT guys.....machine/engine shop reccomendation needed

#1
I need to take a 7hp Kohler K181 to a machine/engine shop to have what looks like a snapped off bit extractor removed from a block and then redrilled and tapped. Do you guys know of any shops north of Hartford that are good and could handle this job? i need this done so i van finish this motor and get the tractor back to getether for spring time. any help would be awesome.
thanks!

the suspect. I got the engine this way. was kinda discovered when i was giving her a tuneup and going to put a new head gasket on it.

I would be inclined to heat the area around the tap cheery red , then hit it with a hard spray from a garden hose to quickly cool it . Then a couple of back and forth turns of the tap with channellocks and the tap will turn out. A little WD-40 will help. The heat won't hurt the cast iron block.

sounds like a good way to crack a block

Are we talking the stub protruding in the center of the picture about 1/8 inch high? If so weld a nut on top thru the center of the nut. It may take a few times at the tap is about 64 rockwell and the nut about 50. Only weld thru the threads of the nut. After it cools a little simply put a wrench around the nut and back the nut and tap assembly out.

some good ideas. the heating and quick cooling of the block concerns me a tad. Id hate to crack the block that would blow.:doah:

harley....i emailed them to see if they could help. they are close by. thanks!

fonz......yes that is it. i dont think its a bolt.....if it is then this bolt has certianly corroided down over the years. The engine is original to a 1966 Wheelhorse tractor. Suprisingly she ran fine with it this way. Ive been "restoring" the tractor with intentions of redoing the engine. Then this was found. I want to make it right before i put the engine back together. Want to do this one right the first time.
Your idea might just work and that is something i can certainly try myself.
will report back when i give it a go. thanks.

useng1 that is one ballsy trick to try . i have seen cast iron that has exploded from shit like that . manifolds that got hot in a fire and when hit with the hose .... well they never did find all the chunks that went flying . the only castings i have seen that doing that trick would work and not split it are . cast steel , not iron but steel , and forgeable castings what ever they are made from .
maybe im wrong but every one i have ever talked to said never ever do any thing like that if you want to try and save the part .
