You know, I don't think I've ever tried to remove or install a pulley with the engine in the car.
Hummmm . . . what would I try here . . . . :idea1:
Pack a bag of frozen peas around the end of the crank. Heat the pulley in your oven (a conventional oven, NOT A MICROWAVE) to about . . . well, till it's too hot to handle. Now that you have blisters on you fingers, put on some leather gloves, grab the pulley and run to the car, yank out the bag of peas and quickly shove the pulley in place. You might be able to push it on far enough to start the bolt. Maybe not. Don't know. Never tried it . . . but it MIGHT work.
Just in case you are wondering "Why frozen peas?" Frozen peas are the best ice pack ever invented. They are cheap. They freeze fast and cold and stay cold longer than any chemical ice pack I've ever found. They will also conform to just about any shape. I learned this from an old man (in his early 80s) that beat me by about 10 minutes in a 5K run when I was in my early 30s. Next time your shins or knees are hurting after you've run a few miles, prop 'em up and put a bag of frozen peas on them. I HAVE tried that, and I KNOW that works. :lol:
