crankshaft pulley removal

VWest77 · Posted: Tue Jun 28, 2011 6:12 pm Post subject: crankshaft pulley removal

Is there a way to take off the crankshaft pulley, without the puller tool? I've been looking around, but can't find any information on this.

Thanks!

3 jaw gear puller should work to get it off after you get the bolt off of it.

And when you put it back, it shouldn't be flush. Don't warp it all to hell trying like I just did!

I have taken mine off with a pry bar behind the pulley. I would pull and then rotate the motor and slowly worked it off. the motor was in the car or I would of used a 3 jaw puller.

Yeah I have the bolt out... just wondering if there is a way to get the pulley off (mine is warped), without using a puller tool. I have very limited access to tools... so looking to macgyver something.

I had a real stuck one, used the John Muir method, 2 big screwdrivers with engine standing on the flywheel, popped it right off.

Smear some anti sieze around when you re-install

I was watching the bug me video on engine tear down. They used either a two screwdriver method or just got one screwdriver & hammered on it where the pulley meets the crankshaft to get it off.

It would work yes but if it is already warped and if you are replacing it, why be afraid of bending it up. Get 2 prybars or screw drivers and go back and forth and work it off. Try that first before buying a tool. Cool

Yea, that's what I thought... but I was reading Rob and Daves write up, and they said Do Not Pry Pulley... because it can cause damage to more then just the pulley.

Yes it can if you are not careful. They are probably talking about the tin getting bent. The call is up to you. Just an idea

you can damage the bore in the case and then the pulley will always leak. The pulley needs to be pulled straight off, like with a puller

I removed my stock one years ago to fit an degreed pulley.

With the engine in the car there is not enough room to put pullers on there.
there is a factory puller tool which fits but not many of us have one of them laying in the bottom of the tool box.

I got mine off with a slide hammer.

I have a suggestion but there is some risk to the #1 crank bearing (thrust bearing). So decide if you want to try it.

Since your pulley is damaged this may be one of your only alternatives if you can't fit any other options.

First, spray penetrating oil on the mounting area of the pulley. Allow time for it to soak in.
Using the plastic handle of a large screwdriver, tap the front side of the pulley toward the rear (removing)... While you simultaneously pull on the opposite side. You are tapping and pulling towards the rear. Each tap should move the pulley a very small amount as it is a tight friction fit. It could take a while but you are trying to tap the pulley off a little at a time. You want it to come off as straight as possible.

If you are not concerned with saving the pulley you can use a metal bar or small hammer to tap the pulley. The impact of metal to metal will create a sharper impact and result in more energy being transferred, but you could easily bend the thin metal of the cheaper pulleys.

The impact to the thrust bearing is much smaller than you are applying to the pulley because the flywheel and crank have a very large mass (large inertia) relative to the pulley and hammer.

As mentioned, there is a bit of risk when using this technique but you asked for "MacGyver methods". Use at your own risk.

Sure synch you boys have never lived on a farm !
No (1) soak it with blaster for two days-- read it a weep -- two days - hit is several times -- blaster nothing else!
Wipe it down
(2) Heat just the pulley with an oxyacetylene torch.
When you do this the pulley gets larger and crushes the rust - works everytime!
Now ya have to not be an idiot when you do this- if you heat it too much you will warp the pulley - if you heat it to little and to slow the nut gets hot and you have done nothing.
Then let it cool - add more blaster -- hold an ice cold rag on the pully then you can damn near take it off by hand

So I did pick up the previously mentioned Princess Auto gear puller... didn't realize it was only a 3"... I don't think it'll span the width of the pulley... but maybe it can fit in the notches though?

I'm currently travelling, and will be back at the Beetle on the weekend, but only have an afternoon and then have to be driving it... so I want to make sure I have everything I need.

If I can't get pullers I'll use the methods suggested above. Thanks for everyone's input!

Peace.
