A grinding hault

J Strickland · Jan 2, 2013

Having fun with my Dad when all of a sudden the snap of a bolt stops everything GAME OVER. While tightening the head bolts down on a free Cub that was given to me I over tightened the center head bolt with the torque wrench. That is what you get for using a tool that you are unfamiliar with. Dad set it for 20lbs a gave me the wrench I started tightening the bolt and did not hear the very low sounding click. Oh well at least the time spent with someone important makes it all worth while. I will try to have the bolt remains taken out soon.

I know a guy down the road who made jigs to drill out the head bolts on a cub. He also made a puller for the crank pulley, which is a bear and some other tools. His number is 740 969 2927.

I broke a bolt in a similar manner which was at least a 1/2" or larger in diameter. I got a center drill and drilled a couple of holes near the edge on one side of the broken off part and another one opposite it near the other side. I stuck a pair of needle nose pliers in the two drilled holes and screwed it right out. Usually when breaking one in the manner you did you just snapped the head off most likely and it wasn't broken because it was having difficulty with threading into the tapped hole. Once you remove the head you might find enough of the bolt above the block to twist out with some vice grips also. Wish you luck in it's removal, Hal.

That little "click" is very difficult to hear, but can quite easily be "felt" once you have just a little experience.

Clamp a bolt in the vise, put the torque wrench on it, and experiment.

bolt in vise to get feel of various torque levels. Great idea. Thanks!

I'm still a bit uncomfortable with the big wrench for low torque bolts.

Anyone familiar with "small" torque wrench for...oh up to 20-30 lbs that may give a better feel?

I'm sure you can find them with little trouble through the various tool suppliers and probably even Sears/Craftsman might have them in their on-line catalog. I've seen smaller size ones calibrated in inch-pounds as well around the airplane world, Hal.
