Aftermarket crankshaft pulley for service belts

[aguiloco]

Hi, I´m planning to change the original pulley from my ZE to an aftermarket and lighter one with lower ratio, but there is a difference between this and the original. Is not the Unorthodox, just an unbranded one from ebay I bought years ago.





Should I move the plate with the tips to match the original? That difference on the crankshaft sensor seems important.

Any information will be apreciated.

Thanks!

Ha.

Ebay crap.


I'd send it back, honestly. You can't just fix that.

The cheap-o ones have been known to come apart too, often with catastrophic results.

I can fix that easily, just new holes and screws turning the plate to match the original pulley.

Can´t imagine how a solid alloy pulley that just moves accesories can come apart, the original screws are really cheap, maybe that´s where other pulleys broke, some quality screws and glue to secure and I think that will be fine.

I'm just another guy on the internet....

But if you want to just re-drill (good luck getting it aligned properly) and use better quality screws (which were indeed the weak point), the be my guest. I have no problems with that, its not my car

I have good and bad experiences with UDPs...

The bad one was a cheapo Ebay one.
Constant slight misfire...retarded ignition timing.
Replaced every bit/sensor of the engine.
Fried two coils...loosened my mind.
Turned out to be that the trigger wheel was wrong aligned

i had an ebay one and th 4 screws on the back plate decided to fall out and the plate knocked out my crank sensor and stalled the car and 3 bolts decided to get imbeded into my timing belt lol

...I could go on.

Aguiloco not to say nothing and you can do what you want but I personally would listen to Ryan!! He knows his way around an MX!! He wouldn't tell you NO unless it wasn't worth putting it on your car, plus he will give you facts to back it up!!
Again do what you want!

I used to be against UDP's, but I now believe it depends somewhat on your motor.

Some of them can't take it for a month, others will for years without problems. It must be a fine difference in the factory balance and what resonances happen because of it.

If you're set on it, don't cheap out. If you save $100 on it now, and then you have to spend 3h fixing it, and then another $100 to fix the timing belt (best case scenario if it fails) then you haven't saved any money at all.
