The most logical reason for the key or tip as you call it breaking off is probably a result of improper torque on the crankshaft pulley or the crankshaft pulley is out of balance.To prevent this I would highly suggest buying a new crankshaft pulley that will be balanced.To explain what happens over time the strain of adjusting the belts from the alternator and power steering and air condition pull the crankshaft pulley with varied tension and can cause the crank pulley to warp to a degree causing it to be unbalanced.While this may seem a bit strange the metal will be affected by this due to age,temperature,torque from the belts tensions pulley left and right.Best bet buy a new crankshaft pulley (note just look at the pulley while idling and see if is wobbling) this will tell you the pulley is warped or out of balance.Plain and simple!
why not get a new motor why not get a new motor ANSWER by welding on the crankshaft while it is still assembled to the engine will most likely melt your seals thus causing you to replace the seals.
Smog pump pulley - are there two hoses running off the back somewhere? then it would be the smog pump (recirs engine gases in the crankcase)
