crankshaft cog question

[fixkick]

i have a 1999 chevy tracker and 1.6L L4 SOHC 16V , my question is is there a problem with the keyway on the crankshaft cog wearing or loosing like on previous models? and does anyone have a picture of the cog from a 1999?

thanks in advance

sure the factory set net torque spec. on the front 17mm head bolt , to 94ft/lbs, in 1996 retroactive to all older, too.
if not set at that torque if fails, the key is only for initial set up , the key has no strength at all.
the problem is folks not reading TSB  or fear the torque wrench. or have  automatic trans and do not know how to lock the flywheel to set it.
it has nothing at all to do with years. ever. (it is ALL BAD service,  you car came new set correctly that is for sure) latter shops do it wrong.
