The bearings from the two rear shafts are not easy to remove. To finish this job I needed a hydraulic press, because these tools are not very cheap, especially  when you need them only once, I decided to make one myself. On a Saturday I wend to the old iron scrap yard and arranged some old heavy iron. From the design I made upfront I already had a rough idea what i needed.

After a number of hours hard work It was finished. Together with the 12 tons hydraulic jack it should do the job.

After placing the two rear shafts into the freezer and heating the race bearing with a plumber burner and about 8 ton of pressure the race bearings came loose, job completed!!
