What are the names of rescue rangers from the 1989 American animated television series produced by Disney?

Chip and Dale are a duo of cartoon characters created in 1943 by The Walt Disney Company. As anthropomorphic chipmunk brothers, their names are a pun on the name of the 18th-century cabinet maker and furniture designer Thomas Chippendale. This was suggested by Bill "Tex" Henson, a story artist at the studio.

In 1989, Chip and Dale became the title characters in a new animated television series, "Chip 'n Dale: Rescue Rangers", in which they formed a detective agency with new characters created for the show: female mouse inventor Gadget Hackwrench, muscular adventuring Australian mouse Monterey Jack, and Zipper the fly. While in the original shorts the duo are frequent troublemakers who are concerned only with themselves, in Rescue Rangers they are crime fighters who help the less fortunate.

In this series the personality differences between the two are more pronounced, with Chip as the serious, heroic leader and Dale as the quick-witted, hard partying reluctant hero. Additionally, they wear clothes in this series which reflect their personalities; Chip wears a leather jacket and fedora (much like Indiana Jones), while Dale wears a Hawaiian shirt.
