MECHANICAL(H4DOTC) > Crank Pulley

INSTALLATION

1. METHOD WITHOUT ANGLE GAUGE

1. Clean the crankshaft thread using compressed air.

2. Install the crank pulley.

3. Apply engine oil to the crank pulley bolt seat and thread.

4. Tighten the crank pulley bolts.

(1) Use the ST to lock the crank pulley, and temporarily tighten the crank pulley bolt.

NOTE:

Set the socket onto the crank pulley bolt so that reference lines (A) and (B) is visible.

(a)

When using 6-point socket

(b)

When using 12-point socket

(3) Draw end line (C) on ST using a marker at the same position as reference line (B) was drawn on the socket in step (2).

NOTE:

It should be approx. 60° when reference line (A) and end line (C) are aligned.

Tightening angle:

60°±5°

5. Install the V-belts.

2. METHOD WITH ANGLE GAUGE

1. Clean the crankshaft thread using compressed air.

2. Install the crank pulley.

3. Apply engine oil to the crank pulley bolt seat and thread.

4. Tighten the crank pulley bolts.

(1) Remove the radiator main fan motor assembly and radiator sub motor assembly.

(2) Use the ST1 to lock the crank pulley, and temporarily tighten the crank pulley bolt.
