You have the older style unit. The newer style does not have the preload pin or the o-ring groove. The newer style fits perfectly and is considered an upgrade.

Let me know if you need anything else,

My older unit had the preload pin. I cannot get the SE106 to mate with my older upper half. The old shaft diameter is 0.860 inches. The SE106 has a 0.875 diameter. I think it is the larger diameter shaft that is keeping the two halve from fitting together. Do I need a different part?

Count the number of splines on the drive shaft of your old lower unit. If it has 13 splines the new lower should work, if it has 9 splines it will not.
