I realize I'm appealing to a tiny, not to mention mentally unbalanced subset of the 968 owner population, but I'm wondering if anybody has ever removed their crank sprocket, and if they have any tips. My engine is out of the car, so I have very good access to the sprocket, but unlike all the other sprockets on the car, which all slipped off easily, this one is very tight. Plus, there is very little space between the sprocket and the front cover, so there isn't a whole lot of room to fit a gear puller. Anybody ever done this? Any tips? I couldn't find anything in the manual about it. Thanks.

After removing the 24mm bolt that holds the crank pulley. Everthing should slide right off including the gear which has a cotter key. the first time I removed mine I did use a puller but after that it just slid off.

Nah, mine's pretty tight. A pry bar won't budge it. I think I'm going to have to use a gear puller.

It's just got a little corrosion under there. With a copper hammer tap it in the "on" direction as well as "off". Break that little corrosion layer and it will slide off.

Thanks, Lance. I'll give that a try. I've soaked it in PB Blaster for the last several hours, so hopefully that will help. The guy behind the counter at Advance Auto (I think he's the store manager) suggested I try grinding down my pulley remover's jaws to get it to fit behind the sprocket, but I'll try your method first.

Well, the ground-down gear puller worked like a charm. No amount of tapping on the sprocket with a punch could get it to budge in th the least, and I was afraid of damaging the soft aluminum front cover piece. I had to grind quite a bit of material from my dirt-cheap Harbor Freight gear puller to get it to fit between the sprocket and the front cover, so the approach I took was to the puller behind the sprocket enough that I was confident it would hold, turn the puller's drive rod enough to see that the sprocket moved a millimeter or so, loosen the puller, tighten the jaws around the sprocket a little more, crank some more, tighten some more, until I could get the puller to fully seat behind the sprocket. From this point, it was smooth sailing.



I'm sure this has been incredibly helpful to the legions of 968 owners out there just chomping at the bit to pull their crankshafts!



Now, it's on to remove the front cover, and get the crank out of there. I'm planning to take the block to a machine shop tomorrow to have them measure the bores to check for roundness and taper, which will dictate how much honing will be required. Hopefully very little.

Ok. Now that it's off, polish the bore of the sprocket and crank journal where this thing goes. ScotchBrite works great. Don't stop until, lightly oiled, it slides on and off smoothly without tools!
