Abstract: A drive coupling for connecting a drive shaft to an output member. The drive coupling includes a non-circular body portion defining a central rotational axis, a tang projecting axially from the body portion on the central rotational axis, and at least one through-hole extending through the body portion adjacent the tang. The tang can shear from the body portion in response to the output member seizing during rotation of the drive shaft. The at least one through-hole provides a flow path for fluid to pressurize a lip seal around the drive shaft.

Abstract: A method for assembling an electrical bobbin requires a spool of wire extending between first and second leads, a housing having first and second opening, and first and second terminal posts, each having a predetermined width. The method includes the step of placing the spool of wire into the housing. The first lead is then extended through the first opening. Like the first lead, the second lead is then extended through the second opening. The first terminal post is extended into the first opening and the second terminal post is extended into the second opening. The first lead is wrapped around the first terminal post to create a first wire wrap. The second lead is wrapped around the second terminal post to create a second wire wrap. The first wire wrap is soldered to the first terminal post. The second wire wrap is soldered to the second terminal post.
