Well, I replaced the timing belt on my wife's '93 945. Thank you all who replied with help. I used the "breaker bar against the frame hit the starter" technique to loosen the crank pulley bolt and I used "rope in the cylinder" technique to tighten it. Everything else was pretty easy. The car started and ran like a champ first time. I did have a minor disaster. I over-torqued the power steering pump bracket nut and broke the bolt on re-assembly. I have those cool bolts that help tension up the belt. I am going to just tighten that belt the old-fashioned way (with a pry bar) and use a nut and bolt from a hardware store, but I would like to replace that nifty tensioning mechanism. Are they a dealer item? FCP Groton? Expensive?

Again, thanks to all who wrote with helpful tips I am very happy to have done this myself.
