Karl Moritz rebuilt the auger head on his CD-1 and sent me the following information:
These are the numbers of the required bearings and seals.
2 1/8″ NTN 389A
1 3/8″ Timken LM48548
1 1/8″ Timken M86647
1 1/8″ NTN 15113
The first picture is of the bearings in the boxes. These are the new bearings and it looks like the NTN bearings used the same part numbers as before. And I believe that’s who made the 15113 one. The other 2 are Timken. The second picture is of the oil seals. I’m not positive of which numbers are the part numbers. On the one it looks like 29x45x9.5 is the size in mm and the other it looks like 21283ssr-bx is the part number.
