Engine Mounting Bracket/Insulator

Removal

  1. Disconnect air cleaner hoses at air horn. Then remove air horn from intake manifold.
  2. Remove upper half of fan shroud extension (for fan clearance when engine is raised).
  3. Remove nuts/bolts attaching front propeller shaft center bearing to bracket.
  4. Mark front propeller shaft U-joint and yoke position with paint or chalk. Then remove front propeller shaft and center bearing as assembly.
  5. Remove bolts attaching starter cable bracket to engine. Move bracket aside for working clearance.
  6. Remove nuts attaching transmission mount to transmission crossmember (Figure 2-2).

  7. Disconnect transmission and transfer case shift rods at shift lever arms.
  8. Disconnect exhaust pipes, brackets, or hangers as needed.
  9. Support engine with floor jack and wood block, or safety stand if vehicle is on hoist. Position block or stand under pan rail at rear main.
  10. Remove nuts/bolts attaching insulators, or brackets to engine and frame.
  11. Remove nut securing engine bracket to stud on starter motor (Figure 2-3).
  12. Raise engine enough to remove insulator, or bracket (Figure 2-3).

  2. Install engine bracket and insulator. Tighten engine bracket-to-block bolts to 30 lb-ft (41 N•m) torque. Tighten insulator stud nuts to 90 lb-ft (122 N•m) torque.
  3. Install nut that secures engine bracket to stud on starter motor (Figure 2-3). Tighten nut to 24 lb-ft (33 N•m) torque.
  4. Align and install bolts/nuts that attach transmission to transmission crossmember (Figure 2-2).
  5. Connect transmission and transfer case shift rods to floor shift levers. Use new spring clips to secure shift rod trunnions to shift lever arms (Figure 2-5).
  6. Align and install front propeller shaft and center bearing. Tighten center bearing attaching bolts to 60 lb-ft (81 N•m) torque. Tighten U-joint clamp strap nuts to 13-18 lb-ft (18-24 N•m) torque.
  7. Install starter cable bracket.
  8. Connect exhaust pipes, brackets, or hangers if loosened/removed for service access.
  9. Install upper half of fan shroud.
  10. Install air horn on intake manifold and connect air cleaner hoses.
