Valve Guide 3313A012, 4223987M1 Perkins

The AGCO Genuine 3313A012 / 4223987M1 Valve Guide is a precision-machined cylinder head component designed for Perkins diesel engines used in agricultural, industrial, and construction equipment. Installed within the cylinder head assembly, this valve guide maintains accurate linear movement of the intake or exhaust valve stem, ensuring stable valve operation, proper sealing, and reliable engine compression under demanding operating conditions. Manufactured from high-quality pearlitic grey cast iron, the valve guide provides excellent wear resistance, thermal conductivity, and dimensional stability under high engine temperatures. Its precision internal bore helps minimize valve stem vibration and side-to-side movement while maintaining controlled lubrication clearance to reduce friction and premature wear. The 3313A012 valve guide also plays a critical role in heat dissipation by transferring combustion heat away from the valve stem into the cylinder head cooling structure. This helps protect the valve train from excessive thermal stress and supports long-term engine durability in continuous heavy-duty applications. Produced to genuine AGCO OEM specifications, this valve guide delivers reliable fitment, smooth valve motion, and dependable performance for Perkins 1000 Series and 1100 Series diesel engine platforms.
