1978 Ford Bronco Engine Mount Exploded Diagram - Insulators, Brackets & Torque
Exploded parts diagram of left and right engine mount brackets and insulator assemblies with bolts, washers and torque values.
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.
