Removing the Crankshaft pulley in situ?

[divace73]

Hi all

What is the best way to remove the crankshaft pulley? I was thinking of putting the car in 4th and chock the rear wheels?
It there a better method?
The radiator has been removed.

That's how I did it - except I didn't need to chock the wheels. Just put the e-brake on. You'll need either a breaker bar or impact wrench. If impact wrench, you'll need to remove the lower grill. I had to apply a bit of heat to the crank nut to get it to move.

Hi Courtenay
When you did this was your timing belt on and if so did the belt skip a tooth at all?

[courtenay]

Yes, the timing belt was on, and it didn't skip. The reason you have to take the crank pulley off is so that you can get the lower timing belt cover off to provide access to the timing belt. Most people, including me, do not put the lower cover back on once they've replaced the belt so that they don't have to take the pulley off to change the TB in future.

I actually got the timing belt on without taking of the pulley, I seem to have a pulley that had a fair bit of room behind it. I need to remove it as I am upgrading my ignition to EDIS and need to fit the 36-1 toothed wheel. I thought while i had my radiator out to get overhauled, I'd do the lot. You know what's it like with a Fiat, while I've got this off, I might as well do this and so on.
I am trying to get my car complete for this coming Sunday, as we have the Fiat Nationals in Australia, although I am not competing, the 2-3 hr drive to the race track is always a buzz with other fiats making their pilgrimage

Update: Some people on the 124 turbo forum suggest using the sarter motor while having the bar against the ground or chassis. This seems to be a fairly common practice......

Further Update

The Starter motor did the trick, got the pulley off have the 36-1 toothed wheel modified to fit. The next challenge was getting it torqued correctly, using a 1.5m bar over the sliding t bar did the trick, it was over the limit of the torque wrench I had up tp 140 ft.lbs.

The starter thing works but could really make a mess of things ( I did when I was younger too!), Now I just put it in gear and wedge the wrench against a piece of wood and the way bar then push the forwards or reverse in 5th (i cunt remember which way). Also, if you place your ratchet on the nut and the handle hangs close to the floor, you can hammer it with a 2X4 (or 2X6, 3pound sledge or a nice taekwondo kick ) a couple of times and this also works.

look up my posts and you will find a link to pics of the tool I made on flickr. The thing was on hellishly tight, far too tight infact and I put it back to 124 Coupe factory specs, same motor after all, and had no problems, not from that anyway.
Look up " tool for removing front crankshaft pulley" or something similar Nov, 2006. Gees, was it that long ago ???

I didn't even bother taking the lower cover off when I first changed my timing belt (back in 1980). I drilled/filed/hacksawed the silly thing off (or enough of it so I could get the belt on/off). I couldn't get the pulley off. It's been that way ever since.

Heat gentlemen heat, and my impact hooked up to 175 psi I'm sure didnt' hurt either, but heat is your friend. (Just in case your still fiddlling with it)

How would one go about removing crankshaft pulley nut on an automatic?

[majicwrench]

The best way to remove crankshaft bolt/nut is with a big chain wrench. It wraps around the pulley and holds it securely.
Harbor Freight has em. They are generally used for plumbing. Google em.

[divace73]

Just hijacking my previous thread, got the crank pulley of (with the starter motor procedure) and back on with a really long bar, however I digress
I became a member ages ago of the italiancarclub.com gallery and thought I'd try and attach a pic
I know there are some links using flicker etc, my question is
Will some work and others don’t?
Test Pic attach

I keep on getting the X image?
