It helps to have the special tools, however, if you have some basic metal fabrication skills, you can usually rig something up. In your case, it might be helpful if you have a puller to take the propeller bearing spool assy. out. It can be made using some steel flat bar and some all-thread (threaded rod...available at Home Depot etc). The bearing spool assy has tight tolerances and can sometimes get corroded making difficult to remove without a puller.
