93 civic lx crankshaft problems

Need Info-my mechanic has told me that the teeth on the crankshaft have
worn down. (How many teeth does the crankshaft have?) He suggested it
could be fixed by welding the harmonic balancer to the crankshaft but
could not guarantee how long that would last. Has anyone out there had any
success with that? Any other suggestions? FYI: I live out in the boonies
and usually have to order my parts off the inetrnet.

 

Does he mean the Woodruff key slot? You can get oversize keys, requiring
only some careful filing to get it to fit.

 

teeth on the crankshaft? harmonic balancer on the crankshaft? afaik,
the civic has neither. can you describe where he means?

btw, he should not be talking about welding anything - guranteed serious
problems. consider getting a second opinion form another mechanic.

 

More detail: About two monthes ago I had to have the head gasket replaced
(not by my regular mechanic. We were traveling.) Apparently these guys
who did the gasket did not put the bolt on the harmonic balancer back
tight enough. According to my regualr mechanic, the bolt was on just
tight enough to cause the balancer to wooble enough for the belt to
eventually fall off. My mechanic show me the balancer and it will have to
be replaced based on the damage. He wants to make sure that the crankshaft
is not damaged before we replace the balancer. The shaft that the balancer
fits on is smooth and he wants to make sure that it is suppose to be smooth
before I invest taht much money in the balancer. I have looked for a photo
of the crankshaft on the internet to see if I can see any teeth on the
shaft with no luck. Hope this helps..

To jim beam--I don't have an option of a second opinion given where I live.
The mechanic actually suggested a new engine if the crankshaft is damaged.
He said that the welding could be done but would not recommend it. I did
disservice to the guy by suggesting otherwise. Sorry.

 

i think you mean the crankshaft pulley - the civic doesn't have a
balancer. if the "tooth" is damaged, like tegger says, you can get an
oversize woodruff key which should do the trick. but if the crank is
damaged, you need a new engine. used engines are cheap & generaly
reliable - *much* sheaper than buying a new crank & replacing it.
