( Pack Of 11 ) 280-3979 VALVE INSERT INLET Suitable For Caterpillar

The product is a pack of 11 valve inserts specifically designed for Caterpillar equipment, compatible with models ranging from 280 to 3979. These inserts are made by the trusted brand CAT and are essential components for maintaining and repairing the engine of heavy equipment. Ideal for business and industrial applications, this product ensures reliable performance and durability for Caterpillar machines.

This pack holds 11 Caterpillar 280-3979 inlet valve seat inserts. A seat insert is the hardened ring pressed into the cylinder head where the intake valve closes and seals. Inserts are replaced during a head rebuild when they are pitted, burned, recessed or cracked, since a worn seat lets compression leak past the valve.

Before you order: confirm 280-3979 in your Caterpillar parts book for your engine serial prefix, and measure the bore in your head before pressing in new inserts. These are inlet (intake) inserts, not exhaust.
