Re: Changing Timing and Crank Gear
I just did this a couple weeks ago on a Model T crank = same principle. I heated the new crank gear in our kitchen's oven @ 500 degrees for about 15 minutes. Using vise grips to carry the gear when heated, I rushed it down to the garage where the crankshaft was sitting in cold winter temperatures. Aligning the gear's slot with the woodruff key in the crankshaft, I slipped the gear over the end of the crank and pushed it home. It slid easily all the way down until it bottomed out. Easy as pie! A couple minutes later and the gear was unmovable. The combination of the heated gear (expanded metal) and the cold crankshaft (contracted metal) worked perfectly. Leave your garage unheated overnight before performing this procedure the next day so that the little extra bit that the cold crankshaft contracts will be just that much more helpful.
