In Reply to: Original Cylinder Versus After-market posted by Kimberly on March 27, 2019 at 12:18:24:
Use whichever cylinder is new. You can't use heat to loosen the top cover. You just cannot generate that much heat over that amount of mass/area to do anything efficient. It requires a lot of elbow grease ( K-Mart has a sale ; > ] ) and a long (4' or longer) pry bar to lift cover. Best to start at the area by the yoke spring and do not gouge the cast parts. Also, avoid smacking the cast parts directly with a steel hammer. Use a rubber dead blow or a piece of 2 x 4 wood with hammer.
