Locate the motor mount on your end cap, leaving a small gap between the top of the motor mount and the inside edge of the end cap.

Use a long drill bit to locate the holes for the mounting bolts and the drive shaft. Use a 3/16" drill bit for locating the drive shaft hole. Use a 1/8" drill bit for locating the mounting bolt holes.

Drill and tap the holes for the mounting bolts. Drill the hole for the drive shaft seal.

Note the locations of the shaft seal and motor mount bolt holes directly above it.

This photo shows the shaft seal in place.
