It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta 9-litre TAD9 and 11-litre D11\/TAD11 diesel application. Technical identification: Split valve cotter that locks the spring retainer to the valve stem; replace as a matched pair. In service, it locks the valve spring retainer to the valve-stem groove so spring load is safely retained.
