Crankshaft Pulley Removal

Frogmella · 5th October 2016, 16:54

One of the jobs that will need doing asap on my much neglected (by previous owners) 75 is a replacement of the timing belt, aux belt and probably the water pump while I've got it stripped.

Been reading Haynes and it talks about getting an assistant to put the car in top gear and press the brake pedal while undoing the crankshaft pulley bolt. Mine is an automatic? What is the procedure?

Secondly, I am concerned about the tightness (205nM) of the pulley bolt, given that today I had to resort to an electric impact wrench just to get the oil sump plug out, is there room enough to get a breaker bar on it? Can I use my impact wrench if neccesary (its always a last resort)?

Every bolt I've had to undo so far has been welded in place by neglect. My back can't take much more of this.

As always, thanks in advance for any advice.

You will get a breaker bar in with the wheel off, although and impact gun will probably work better.
I've always been told that using in impact gun to remove them is ok if it really wont budge but they should never be put back on with an impact gun, this is certainly true for Honda's anyway.

Automatic is as simple as leaving the car in park.

Remove the starter, put a 1/2" extension bar through the hole in the block casting and into a recess in the flywheel like this:

The flywheel on the auto may be different, but the approach would be the same.

Well I am confused now?

There is a mountain of info on how to remove the crank pulley in the search feature above.

DO NOT try to lock the crank as advised above. The impact by doing it this way can very easily damage the crankshaft and then you are really in the poo.

There is a tool that locks onto the pulley so that you can safely use an impact hammer.

I used a cordless electric impact wrench. Worked a treat with no movement at all of the crank pulley. Mine is an auto too.

I have a good quality 18v impact wrench. Do you reckon that will do the job ballymenaman? Also, what had to be done after the bolt was removed? Was a specialist puller needed to remove the pulley?

The only way to find out is to try it. Guessing won't help.--

Undo the bolt and the pulley should just pull off.---

There is a special tightening sequence required, once new pulley is fitted , tighten to 100nm using torque wrench, then tighten 60 degrees, then 30 and 30 again. you will need a heavy duty socket, extension bar and power bar to do this, at the same time holding the pulley with the locking tool that John mentioned . When we did mine earlier in the year, we had to use 3/4 drive socket ,extension and power bar to even get the bolt to move after the first 100nm.
