I went to replace my impeller in the fall and ended up replacing my drive shaft because the threads got chewed up during disassemble.

Hoping someone has better details or actual factory descriptions or pictures.
I have searched online and YouTube and found very little specific information

The (service manual) provided very little information regarding replacing the drive shaft, and also shows a simple picture of the two oil seals.

1. I went off old shaft and measured for pressing in the new shaft.
2. The oil seals had metal faces on both, trying to verify correct install and assembly

Thanks in advance for the help
I am sure this is simple for somebody who frequently works on these parts
