Sundstrand Sauer Danfoss Series 90 Charge Pump Shaft Key Change

The charge pump shaft key and woodruff key have been changed on the 42cc models.
Reasons for the change is that the new key is smaller in design and helps get rid of a conflict problem.
The old charge pump shaft will no longer be available, nor for service parts either.
They are interchangeable if it is in the affected serial number range and if they are replaced together.
