Hey guys, I just built a minime consisting of a SOHC ZC block and d16z6 head. I used a d16z6 crank pulley (that's fine right?) and somehow the crank pulley fell off, as in the crank pulley nut is in but the pressed in part came off.....wtf???

Does anyone know what crank pulley's are interchangeable??? Like can i use a d16 from a 96-00 civic? or even from a d16 from the EF's??? Oh and are those inexpensive ebay ones okay to use??? thanks!!!

 

So you are using a SOHC ZC non-VTEC block (that's basically the JDM version of our A6)?

I don't understand what you mean by the "pressed in part" came off - did the treads in the crank get destroyed or what? Did the pulley itself come apart?

The A6 pulley would be the one most similar to yours, but I believe that the Z6 or Y8 would work also. Stay away from the lightweight pulleys and the 1.5 L pulleys as they do not provide the damping that the stock pulley does - read:if you use the lightweight pulley it will eat your bearings up.

ok thanks for the advice, i'll probably end up gettin a d16z6 or d16y8 or d16a6 crank pulley then. and yes, i dont know how to explain it...but the outer part slid off the inner part of the crank pulley. its like the threaded parts was pressed into the inner circular part of the crank pulley....

 

anyone?

 

Take a picture because you're not explaining it well enough for us to understand.

 

Picture of a crank pulley (not mine)

 

LOL...WTF?! Never in my life have I seen that happen. I'd chalk it up to a freak accident and get another one.

Haha. Have a on me .

Yea, my bro was test driving the car, and he heard a loud clunking, figured he blew the tranny or something. Came back to the house, and find out the outer piece slid off, how the hell can this happen??? Did i have the alternator belt too tight??? Well this crank pulley was sitting outside for like 2 years in wisconsin weather so maybe that messed it up???

it's because the stock crank pulley is a harmonic damper. the inside and outside parts are bonded together by rubber, to form an elastic layer to balance out the bottom end harmonics. The rubber can rot after awhile and break.

Ah. There it is. Rubber doesn't do well outside. Don't use shitty parts and shitty things will happen much less frequently.

 

ah....that explains it all, all that winter coldness then summer heat, plus the rain/snow/salt probably killed it.

I use this method at work all the time to break free seized bolts, heat it up with a torch (expansion/summer), then slap a wet rag on it to cool the bolt quickly (contraction/winter), and repeat as needed till the bolt breaks free.

I'd say it was a combo of the rubber damper rotting as well as the rubber actually breaking free from metal.

Haha, wierd.

 

ive seen it in person...weirdest then i've see too...
