Aftermarket valve spring retainer (valve spring seat) 5I-7625A — a direct replacement for the Caterpillar 5I-7625 retainer. It fits the Caterpillar 3066 / S6K / C6.4 diesel engine family (also 3064 / C4.2), commonly used on CAT 311 / 312 / 320 excavators.
The retainer holds the valve spring and (with the collets) keeps the valve on the stem. When the retainer face or the collet seat wears, valve stem height changes and the keepers can loosen — typical signs are valve-train rattle, a popped or dropped valve in severe cases, and compression loss. It is normally renewed together with the springs and collets during a cylinder-head overhaul.
Supplied as a single retainer (hardened steel). Confirm the removed number and the engine reference before ordering; tell us the quantity because the retainer is fitted per valve.
