For 356B thru 912 -- This is the upper pump gear assembly for the Late (large) pump. The drive tang fits into the slot in the camshaft. Often the drive tang is excessively worn and there is wear on the bearing end. In that case, we suggest replacement with this new assembly from Germany.

For reference, this gear was Factory installed starting with the following engine numbers:

• Normal: 601994
• Super: 85941
• Super 90: 800150
