"It is with great sadness to share the news that Beau Kazer passed away on December 30th in Thousand Oaks, California," a representative for the show said in statement. "He is survived by his wife, Sharon Alkus who wanted everyone to know Y&R was a large part of his life that he was very proud of."
Kazer originated the role of Reynolds in 1974. He left in 1980, but reprised his role several more times beginning in 1984. In 2013, he appeared as part of the show's tribute to Jeanne Cooper, who played his onscreen mother, Katherine Chancellor. Cooper passed away in May 2013 at the age of 84.
Daniel Goddard, who appeared alongside Kazer as Cane Ashby, remembered the actor in a Facebook post on Tuesday.
"The Young and the Restless has lost another of its own... RIP Beau Kazer (Brock)," he wrote. "I remember the first time I heard your voice and thought wow! This guy should have been in radio! Then I watched u act and was blown away with how natural and honest your performances always were. God Bless."
Kazer's other credits include General Hospital, Taxi Driver, and Hart to Hart.
A cause of death has not been revealed.
