I talked a GOOD Friend of Mine into Doing the Work as I took the Pictures.
Believe it or not, HE’s Still a Good Friend.
Rebuild/Replace Water/Oil Pump Seals – Work Performed by Skipperthedog MASTER Backyard Mechanic
If you must change the Oil Pump Seal, the Engine must be pulled and the Engine Case removed. If only changing the Water Pump Seal, this may be done with the Engine left in.

REDNECK Water Pump Tool—select a Socket that just fits around the inside rubber pump, so that it is sitting against the Copper Lip on the Seal
Socket Size ??? 1 ¼”
Place the Engine Case on a Flat Solid Surface and Tap the Seal Gently until it is Bottomed Out

Use a Socket as big as the lip on the Seal MAYBE 1 ¼”
Hand Press the Seal UNTIL it Bottoms Out

Turn the Socket Upside down
