Description of Change: A new integral seal replaces a gasket in the water lines groups on the engines in these machines. The illustration shows the location of the seal. The integral seal has a rubber seal bonded to the inner edge of an aluminum plate. When compared to the former gasket, this new integral seal will provide improved resistance to coolant leaks.

Location of the new 127-2176 Integral Seal (1).
