Removed the guard and belt. Heated the flywheel with a propane torch. Careful not to over heat it. Flywheel came off easily with a 3 point puller. Removed the cap and pulled the old seal out. Cleaned the bore in the cap to get all the oil out and dried it. Started the seal into the cap with the letters out. Carefully pushed the seal down into the bottom of the cap with a long socket slightly smaller than the bore. Put a little oil on the inside of the seal and put the cap back on. Reheated the flywheel somewhat again and tapped it back on the shaft with a brass drift. Put the belt and guard back on. Started the compressor. No more oil leaking around the shaft.
