Crank Pulley

btwilson86 · 07-23-2009, 03:16 AM

So I got ready to get the crank pulley off to see what's wrong with my crank timing gear, and I found out that the crank pulley is spot welded to the shaft. Seeing as how a Crank shaft is pricey, and the harmonic balancer is over $500 from the stealership, and I don't have the money to go out and buy a JDM motor, does anyone have any idea on how to remove the pulley in a way that may leave the crank and the pulley salvageable?

I have me a used pulley, so I don't care about what happens to the one on the car. Anyone have an idea on how to get it off while leaving the shaft in good shape?

I think the only option is to grind the welding off, the one thing that would worry me; is why it was it welded in the first place.? Could be the keyway slot is damaged in the crankshaft or the shaft damaged. If that’s the case then you will be back where you started.

Yeah, that's what I've been thinking (cutting the weld). Gonna have to get a little creative on accomplishing that. I do believe the keyway is damaged, or the key is missing because my timing will retard under heavy driving (belt does not jump, good tension, crankshaft timing gear is slipping). I had talked to the owner of the car about 50,000 miles ago and he said the pulley had worked itself off while driving to work. Didn't mention he had it welded on though...

Do you guys use a standard 3 arm puller to get these pulleys off? Mine is stuck as predicted. Thanks

Aren't you supposed to use the type that screws in with the 2 bolts?
