As much as really I don't feel like doing it, my leaking timing cover gasket needs replacing. It looks pretty straightforward. I already removed the radiator, fan and water pump pulley. The front motor mount will have to come off. The manual says to lift up the engine in order to remove the crank pulley/hub, which I assume is to make room for the hub puller.

 

The exploded view in the manual also shows a "jaw" and "washer" in front of the hub, so I'm guessing the jaw is the bolt/nut that holds the hub on? Is this correct?

 

For anyone that's done this job before, any tips or tricks would be most appreciated.

 

Thanks

I would suggest you have a speedi-sleeve on hand for the hub, it is most likely badly grooved.

 

A pic of the exploded view you are talking abut might help sort out your questions, but right now I am guessing you are correct.  I've never pulled one in the car, just on the engine stand.

 To get at the front timing cover you’ll need to remove the front engine mount.  You need to support the engine to do that. The rubber on your front mount looks poor. It should be replaced. 
 

You’ll need to remove the centre crank bolt. Then a puller to get the pulley off. Look at the sealing surface of the pulley. Clean it up. You may very well want a speedi-sleeve on it. Remove timing cover bolts. Remove timing cover. Kerosene and a brush. De-sludge everything. Clean all mounting surfaces like new.  How’s the timing chain play looking? Install a new crank seal in the cover with a press. Get a new gasket in place. I like to copper spray both sides. Lay the cover and gasket in place. Do not tighten it down. Use crank pulley as centering guide. Install pulley. Then tighten down cover bolts.  Put thread sealer on cover bolts.

Very thin walled sleeve that can be driven over a shaft or hub in this case to repair the area the seal has worn a groove in the shaft or hub.  This increases the diameter of the shaft or hub slightly, gives the seal a fresh, smooth surface to ride on.  They come in various diameters and widths.

At the 18:35 mark in this video, I install a speedi sleeve on my crank pulley. Front seal surface area.

At the 3:25 mark here I install front timing cover and gasket. The crank seal install in the timing cover is shown earlier in the video.

Since I was in there, I figured I'd replace the front engine plate gasket in case that was contributing to my leak. Also, when I did the oil pan gasket last winter, I didn't replace those little rubber seals on the plate package, so that will get done too. 

 

Do you guys think it would be ok to reuse the oil pan gasket since it was just been replaced? It looks fine.

 

And the sealing surface on the hub looks good so I don't think I'll need a speedi sleeve

You should reconsider the speedi sleeve. I don’t consider that as looking good.
