Well, it is time to do a timing belt replacement on my 88 Mustang 2.3L. I've done them before, but I've always been elsewhere and had air tools handy. I don't have an air compressor avalable, so to save myself some time and money, is it possible to change the timing belt without removing the crankshaft pulley? I crawled under the car and there seems to be a little space between the inner timing cover and the belt guide. Anyone ever done this? Or does the pulley have to come off? I have a gear puller, but I am not sure how to get the pulley bolt out without rotating the engine accidentally.
