I'm restoring my 48 C and today decided to begin rebuilding the bottom half of the engine. Now in a moment of dim thinking I decided to put a puller on the crank pulley thinking it is steel and not CAST! Well, I quickly learned how wrong I was as I picked up part of the broken pulley off the garage floor, and the pulley is still on the crank! Does anyone out there have a crank pulley I can purchase or give me a lead on finding one. This is the first thing I have ruined since starting this project and I am finished with most of the other parts of the tractor. Thanks everyone.
