UPDATE 2-Navistar says chief risk officer to retire

* Retirement effective Oct. 31

* Company says move not due to disagreement

(Adds company comment, background)

SEATTLE, Oct 16 (Reuters) - U.S. truck and engine maker Navistar International Corp (NAV.N) said on Friday its chief risk officer, William Caton, will retire effective Oct. 31.

Caton joined Navistar in October 2005 as the executive vice president of finance. He was named chief financial officer in September 2006 and took up his current job in June 2008, according to the company's website.

During his time with Navistar, Caton has overseen its financial restatement and reporting process, the company site said.

Caton's decision to retire was not a result of any disagreement with the company or its management, Navistar said in a filing with the U.S. Securities and Exchange Commission.

A successor will be named at some point, company spokesman Roy Wiley told Reuters.
