The rear cover on this style of motor is held in place by four rivets that are compressed in to holes in the gear housing.
The rivets need to be drilled out just a little bit to weaken them enough to pry off the cover. Begin this process by drilling the rivets about 1/4" deep with a small drill bit, smaller than 1/8".
Repeat with all four rivets.
