I have a friend who has had to replace his crank pulley AKA harmonic balancer once already on his 99' prelude and apparently needs another one according to Honda. What could be causing this problem to occur twice within a one year span?

Also ATTS light comes on and off randomly at times, for ex. my friend drives down the street and it would come on for like three minutes then wont come on again until the next day or w/e. is there any way to get this to stop?
Can a code reader solve this problem?

LMK.

 

anyone??

 

Not getting it torqued to 180ft/lbs. and not replacing the wooddruff key. Also belts on too tight.

 

Code reader won't grab the code for the ATTS unit, you'll have to use the blinking light method and then report back for us to help you. If he hasn't already, change the fluid out in the ATTS unit.

 

this may be a bit extreme but i've heard of crankshaft wobble before, though i need to actaully research it myself to see if there are any truths behind that

anyone?

 

sounds reasonable, anything else that could cause it to become defective?

 

Well any other guesses are just theories or myths, but - 8lb flywheel, or solid motor mounts.

Is he replacing the pulley with a honda part or aftermarket?

 

This makes no sense but I'm going to go with no.

And if the crank is messed up, you can replace pulleys all day and it'll still wobble.
