follow up to horrible vibration problem

Toeclicker · 12-16-2003, 11:39 PM

For those of you who were kind enough to help me out with my problem and for those who may have the same problem, this is the answer to my HORRIBLE vibration problem... I have a 93 lx 5.0 and right after i put in my new aluminum radiator i had a bad vibration. It gradually got so worse that i couldnt drive it anymore. I checked so many things including my harmonic balance even though it was brand new. But i decided to take it off for the hell of it (the balancer that is) and sure enough there was the problem. the little groove for the spline on the crankshaft that the balancer sits on was completely worn on the inside of the balancer. There was no idication of any groove whatsoever because it got loose somehow and just wore it away and also crack the balancer. Because of that, the bolt for the balancer that connects to the crankshaft worn and had metal shavings all over it! So that was my problem, i just hope they make a heli coil big enough for that huge bolt cause i doubt i will ever find one usuable considering its been discontinued for some time now, but in any event, i hope this is some insight for someone and i also want to say "THANK YOU SO MUCH" again for all the help from everybody and watch out cause ill be back on the road!!!!!

The damage to your crankshaft does not sound good at all.

the crank shaft cannot be fixed if it is stripped. i know someone who did the same thing thought he had it fixed and serious poroblems after that.

Sorrry it came down to that.

But, thanks for posting the solution here. This thread will be a help to somebody down the road who does a search trying to figure out their problem.

Dont fight it. You might as well go ahead and pull the engine and yank your crank out cause it is now junk.
