New Camshaft Housing Gasket Has Increased Resistance To High Temperature{1113}
Usage:
D10, 641B, 651B, 657B, 776 Tractor Engines;
D348, D349 Engines;
777 Truck Engines
Description of Change: New camshaft housing gaskets with increased resistance to high temperatures are used in the above engine models. The new gaskets have a layer of material on the exhaust side which prevents gasket distortion and oil leakage better than the former gaskets.
Adaptable To: The new camshaft housing gaskets are direct replacements for the former camshaft housing gaskets, as shown in the chart. A quantity of 2 gaskets is needed for most engines.
