Part of 1978-1979 Ford Bronco Exploded Parts Diagrams
This document is an exploded parts diagram showing the engine mount (motor mount) installation on a frame crossmember, uploaded as applicable to a 1978 Ford Bronco. The illustration identifies the right-hand insulator assembly (part 68032) and its mounting bracket (5057), plus the left-hand insulator assembly (6038) and left-hand bracket (5058). Fasteners are called out with part numbers and torque specifications shown in parentheses (ft-lb implied): a 7/16-14 x 1.00 bolt (304685-S2) torqued to 45-55 with a 7/16 dia. lockwasher (34793-S2); a 7/16-14 x 1.00 GR5 bolt (304688-S2) torqued to 30-40, also with a 34793-S2 lockwasher; a 7/16 flatwasher (381589-S2); and a 1/2-13 GR5 locknut (34979-S2) torqued to 40-60. Arrows show where each fastener and washer attaches the brackets and insulators to the frame. A reader can learn the correct hardware, part numbers, assembly orientation, and torque values needed to remove or replace the engine mounts and brackets. A footnote states 'Torque shown in parenthesis.' The document itself carries no year, model, or engine designation.
