New BrakeSaver Control Valve Group Has Improved Diaphragm{1159,1155}
Usage:
3406 and 3408 Truck Engines Equipped With BrakeSavers
Description of Change: A new BrakeSaver control valve group with an improved diaphragm is used on 3406 and 3408 Truck Engines so equipped. The diaphragm in the new control valve group is made of a material which has more resistance to heat than the material in the diaphragm used in the former control valve group. For this reason the diaphragm in the new control valve group will give longer service life.
Adaptable As: The new parts are direct replacements for the former parts as shown in the parts chart.
