Hey CHeck out this video and let me know what you think. Seems to wobble a bit to me, but I never looked prior to the 185 install. My GTP runs smoother..

How does this compare to your car?

I would not drive it like that.... Good way to **** a bearing on your motor. Seems like a few people have similar issues. Are their torque specs?

I just got a HE from Eurocharged and had to modify the inside of my bumper with tin snips and a drill to get the bumper back on. Works great though.

ML500K

that's exactly what i have, but not as much, did you torque the screws holding the 185 to 35lbs? Make sure you do that. When I raise the rpm to 1000, the wobbling goes away. I'm still waiting for answers from Eurocharged to see if this is normal. You can check my video here: http://www.youtube.com/watch?v=MY9wDPOrdKQ

i have a 185 and it doesn't wobble like that. i'll double check but i dont think it does. Thats quit a bit of wobble.

ML500K

please do let us know if yours wobble at all, just a little bit or not at all it idle. Thanks!

CLKCLK

Mine does a bit but not that much and yes it goes away at high RPM. It has been more or less than a year like that so I think it's ok.

From what I've heard the dampening doesn't kick in to a little over 1800rpm or so. If you give it some gas and bring the revs up you will notice it is straiight as an arrow.

ML500K

that's comforting to know... wonder why it is not torque at the shop to 35lbs.

testknight

ML500k, I'd be looking for input from others, but looking at your video, it doesn't seem to be bad. We beleive mine was and its what tore my seal...but looking at your video, it doesn't seem as bad as mine is.

I sent Eurocharged the video last night, they are just having me send it back in so they can be sure its balanced properly.

^^^Glad to hear they're taking care of you, that's solid customer service.

To everyone else - there's only one way to know for sure if your wobble is acceptable - have your pulley's runout measured. MB has a published spec for what runout is allowable for the crank pulley - any excess from that level should be considered a risk, IMHO.

here's the vid as i promised. sorry for the bad lighting but basically there is no wobble at all on my 185.

Its weird, when i use my iphone video or an Sony HD cam, i don't seem to capture any wobbling effects, however viewing naked eye, i can see it. If you look at the belt tensioner, does it move at all? How does it look to you via naked eye? can you see any "wobbling" ?

TemjinX2

with the naked eye, both crank pulley and tensier pulley's dont move. But i also have the pulley saver kit installed, so its not quit apples to apples comparison.

ML500K

Hmm, then that means there is a problem. The belt tensioner does vibrate back and forth and i can see it is caused by the 185 crank pulley. Think adding the pulley saver doesn't really change the pulley spinning characteristics...Maybe it needs to be balanced ...

testknight

Its your capture rate of the camera...if you can change the setting (not sure you can on Iphone) to 600fps you'll see it better.

TemjinX2

i'll try to take another vid with better lighting

ML500K

here is a clearer video of the wobbling at idle. its torque to max at 36lbs.
I started from 33 all the way to 36 but it doesn't get any better than this.

My tech told me "any wobble" at the crank is BAD!! Thats why I did the Code III pulley. My stock crank was wobbling a lil (like yours and got progressively) worse ). I just replaced it with the OEM crank pulley from MB. paid about $185. I don't believe that the 185 should 'wobble" at all. I've seen many at the track that did not wobble (Jerry's and Jakes).

ML500K

I'm already in contact with EC to have them send me a new that is one that is pre-balanced, cause I feel this is unacceptable. Will update how this turns out.

I just looked at the OP's video and actually it doesn't really look that much different, only slightly better...

ML500K

Did you just receive this pulley from EC? If it is, this batch really has some problems. They are asking me to sent it back to have it balanced, i wonder why it is not pre-balanced beforehand. Its not time to start complaining but so far two out of three items got from EC have had problems.

jturkel

ML500 and Testnight's pulleys appear to have a bit too much wobble IMO. Wobble is bad (Newzchpsy is right) because it can end up rubbing on the rear main seal and cause it to leak or blow completely (it has happened to me). i was very skeptical about putting a crank pulley back on after my experience, but luckily i havent had any problems with my 185mm crank pulley thus far (installed since March).

ML500K

I totally agree that wobble is bad, i first noticed it when it was installed. My iphone video camera somehow didn't capture that effect and i didn't get any response from EC for about a week. it was when i sent them the updated video that they say to sent it back for balancing or whatever they plan to do.

Are you referring to the front Crank radial seal or rear radial seal. if its the rear one, that will be hard to replace. The front radial seal i do plan on replacing when i get the replacement "balanced pulley" .

jturkel

sorry. the crankshaft radial seal. mine blew from a wobble when i had a 178 evosport pulley...but thats because i installed it with a used crank bolt

ML500K

Do you think it is too much to ask them to send me a balanced pulley so that I can swap it out with this defective unit? I guess I'll need another new crank bolt or two...

ML500K

i'm just gonna take it off and sent it back for them to check and re-balance. I'm am not happy.
