Crankshaft pulley....info/help

[NEXVCTM]

Well my crankshaft pulley decided 2 separate tonight....just wondering 1st if this has happened 2 anyone?.....2nd anything I need to know about getting this thing off?(dropping motor,tools needed,anything that would help me get it off the car easier/quicker????)got the TQ spec.....please reply only if you have changed 1 on these car b4.




Thanks in adv.

To get it off, you won't have to pull the motor. You should be able to jack the car up, take the drivers side tire off and the crank pulley should be visible from there.

If you have air tools, it'll help, a TON. Otherwise, a breaker bar and something for leverage, they're on there pretty tight.

Yeah that happened to me before except I was on the freeway.

As far as removing ot there is a crank pulley tool you can buy from an autopart store,you can use the torch method then impact it off,or impact it off if it 400lbs of torque or more,or you could have your car to a shop and have them do it which is what I did.

I'm pretty sure others will help out too.

Yep, that bolt can be a bitch. It all depends on the last guy who torqued that bolt on. If it was a professional, you can bet that he did not use a torque wrench. For sure he used his air impact wrench. So, it depends on how much clockwise torque his wrench had.

Did you know that the max torque ratings for impact wrenches is actually the counter clockwise rating ?

Good luck

Thanks 2 all who have responded......if ya got it keep the info coming will b starting this adventure about lunch time...another Q is will i have 2 drop the motor some to get the puller on the pulley???? looks 2 me as if the damn thing won't come off the car unless it is dropped some because body of car could interfere but don't know.

The crankshaft pulley incorporates a harmonic oscillation damper (to stop the crankshaft from eventually being destroyed by uncontrolled high rpm oscillations). These consist of a heavy metal outer ring (usually cast iron because cast iron is heavier than steel) attached to the pulley centre by a vulcanised rubber insert.

This rubber insert allows the two damper components to move with a degree of independence from each other, but at higher rpm this flexing of the rubber insert causes it to heat up, and eventually this heat cycling leads to the rubber breaking down, and the damper failing. Oil doesn't help.

Any signs of degredation of the rubber damper insert (cracking, seperation, softness from oil contamination etc) should prompt you to replace the damper / pulley immediately. Any damper that is revved fairly high more than occasionally, or if the damper is old or of unknown age, should be inspected regularly.

this I know.......thanks tho

Well no luck today try again tomorrow.How do you stop the crank from spinning?

[wed3k]

put nylon rope in one of the cylinders.

who the fuck are you.
ok first of all, if you knew ANY of what "johnl" said, you wouldn't ask how to take a damn crank pulley off.

and when a respected member of the board gives you advise, dont be a smartass. you asked for help and they are helping.

and to reiterate, if you remove a spark plug, and insert enough nylon rope into that cylinder, it will stop the piston from reaching TDC and going back down, which will stop your motor from turning, thus allowing you to remove the bolt.
he wasn't being a dick.

thank you.

[nostringz]

try NOT to use a torch, we did on an integra and created a lip on a crank shaft... had to dremel it flat... LMAO... fuck...

the damage could have made it so the pulley cannot be removed and may be necessary for a torch

well you have to take into consideration that not everyone knows much about cars...to some one that doesnt know much about cars that idea would seem ridiculous...

Another possible explanation could be , thats the op is a hot head and jumped the gun.
