Flywheel Housing

Usage:

MTC855 818

Type 1




Illustration 1g00763300

Note: During assembly, inspect the following components for any foreign materials: the front face of the flywheel housing, the two sides of the flywheel housing gasket and the rear face of the cylinder block. These components must be free of the following substances: oil, fuel, water, gasket adhesive, assembly compounds and any other foreign material. After the flywheel housing is installed, cut the gasket even with the pan rail.

(1) To tighten the flywheel housing bolts, use the procedure that follows:

  1. In a numerical sequence, tighten bolt 1 through bolt 9.

    Torque for bolts ... 100 ± 20 N·m (74 ± 15 lb ft)

  1. In a numerical sequence, tighten bolt 10 through bolt 20.

    Torque for bolts ... 40 ± 10 N·m (30 ± 7 lb ft)

  1. In a numerical sequence, again tighten bolt 1 through bolt 9.

    Torque for bolts ... 135 ± 20 N·m (100 ± 15 lb ft)

  1. In a numerical sequence, again tighten bolt 10 through bolt 20.

    Torque for bolts ... 55 ± 10 N·m (41 ± 7 lb ft)

Type 2

Note: During assembly, inspect the following components for any foreign materials: the front face of the flywheel housing, the two sides of the flywheel housing gasket and the rear face of the cylinder block. These components must be free of the following substances: oil, fuel, water, gasket adhesive, assembly compounds and any other foreign material. After the flywheel housing is installed, cut the gasket even with the pan rail.

(1) To tighten the flywheel housing bolts, use the procedure that follows:

  1. In a numerical sequence, tighten bolt 1 through bolt 24.

    Torque for bolts ... 40 ± 10 N·m (30 ± 7 lb ft)

  1. In a numerical sequence, again tighten bolt 1 through bolt 9.

    Torque for bolts ... 135 ± 20 N·m (100 ± 15 lb ft)

  1. In a numerical sequence, again tighten bolt 10 through bolt 24.

    Torque for bolts ... 55 ± 10 N·m (41 ± 7 lb ft)
