Jerry Van Dyke, who after decades in show business finally emerged from the shadow of his older brother, Dick, with an Emmy-nominated role in the long-running ABC sitcom “Coach,” died on Friday at his ranch in Arkansas. He was 86.

Jerry’s wife, Shirley Ann Jones, who confirmed the death, said his health had deteriorated since a traffic accident in 2015.

From the beginning, Mr. Van Dyke’s television career was intertwined with his brother’s. One of his earliest TV appearances was in 1962 in a two-part episode of “The Dick Van Dyke Show,” as Stacey Petrie, the would-be comedian brother of Dick’s character, Rob Petrie.

A boisterous performer who supported himself with a banjo-and-comedy stage act when television or film roles were scant, Mr. Van Dyke was a ham to his brother’s more dignified persona. But while Dick had runaway success early on, with the Broadway show and film “Bye Bye Birdie,” the Disney musical “Mary Poppins” and “The Dick Van Dyke Show,” his brother’s career was long defined by a string of short-lived projects, like “The Judy Garland Show” and the game show “Picture This.”
