A nonunion Navistar plant is supplying Ford with diesel engines as the companies remain locked in a pricing dispute and Navistar deals with UAW strikes.
Navistar International Corp. is relying on subsidiary International Truck and Engine Corp.'s Alabama engine factory to help it weather a second week of UAW walkouts.
International spokesman Roy Wiley said production increases ordered at International Diesel of Alabama LLC in Huntsville will ensure that a steady supply of diesel engines for Super Duty trucks reaches Ford Motor Co. while negotiations continue.
"They have all the capacity in the world there. This is not a big issue for them," Wiley said.
