1982/06/23 Caterpillar


Improved Water Separator Group Used

Usage:


1673, 3208, 3306 Truck Engines

Description of Change: An improved water separator group is available for these engines. The new group has a new base and uses straight thread fittings with O-ring seals. The former group used tapered thread fittings and these at times caused cracks in the base when too much torque was used on the fittings. The new group will have a longer service life.

Adaptable To: The new 9N6519 Water Separator Group is a direct replacement for the former 7N950 Water Separator Group, which is canceled.
