Valve Collet 3142W005, 4226310M1 Perkins

The AGCO Genuine 3142W005 / 4226310M1 Valve Collet is a precision-engineered valve train locking component designed for Perkins diesel engines used in agricultural and industrial equipment. Also known as a valve cotter or valve keeper, this critical component secures the valve spring retainer to the valve stem, ensuring stable valve positioning and reliable engine operation under high-speed and high-vibration conditions. Manufactured from hardened high-strength steel, the valve collet is designed with a precision-machined tapered locking profile that fits securely into the valve stem groove. When installed as a matching pair, the collets lock tightly against the valve spring retainer, preventing valve displacement and maintaining accurate valve timing throughout continuous engine operation. Engineered to withstand extreme mechanical stress, repeated spring pressure, and elevated cylinder head temperatures, the 3142W005 valve collet provides long-lasting durability and dependable retention performance in demanding diesel engine environments. Its precision fitment helps reduce wear within the valve train assembly while supporting stable combustion efficiency and engine reliability. Produced to genuine AGCO OEM specifications, this valve collet ensures secure valve retention, precise compatibility, and reliable performance for Perkins 900 Series, 904 Series, and 1100 Series engine platforms.
