NOTE:

Replace bolts that are tightened to the specification.

Replace self-locking nuts and bolts and seals, gaskets and O-rings.

The hose connections as well as the air guide pipes and hoses must be free of oil and grease before installing.

Secure all hose connections with hose clamps of the same type as those equipped by the factory.

To secure the air guide hoses on their connections, spray the clamps used previously with rust remover before installing.

When installing, bring all cable ties back to same positions.

-- Checking position of torque converter.

When the converter is installed correctly, the distance -a- between the lower contact surfaces on threaded holes and on the torque converter and torque converter bell housing contact surfaces is at least 23 mm.

WARNING:

Danger of causing damage to the torque converter drive plate or the ATF pump.

The distance is approximately 11 mm when the torque converter is not fully installed.

-- Turn the torque converter and the engine drive plate before connecting the engine and the transmission so that the holes for the bolts -1- are at the same height as the opening on the removed starter.
