Removal and installation of the crankshaft pulley

Withdrawal

1. Remove the accessory drive belt. Remove it completely or only from the crankshaft pulley - depending on the procedure performed (Chapter 1).

2. If necessary, turn the crankshaft until the MGR marks are aligned (paragraph 4).

3. When unscrewing the bolt securing the crankshaft pulley, prevent the crankshaft from turning. Follow these instructions:

A) If the engine/transmission unit is installed in the vehicle:

• 1) On manual transmission models, shift to top gear and have an assistant depress the brake pedal.
• 2) On vehicles with automatic transmission, remove the small metal cover bolts from the sump. Use a power screwdriver or similar to block the faceplate ring gear while your assistant removes the pulley bolt. Do not damage teeth or adjacent components.

b) If the engine/transmission has already been removed but not separated:

• 1) On manual transmission models, remove the starter (chapter 5) and block the flywheel in the same way as in step 2 (see above).
• 2) On models with automatic transmission - see point 2 above.

V) If the engine/transmission has already been removed and separated, perform the operation shown in fig. 21.11.

4. Turn out a bolt of a pulley and remove a pulley (see fig. 8.4, a, b).

Installation

5. Installation - in the reverse order of removal. In this case, the keyway of the pulley should sit on the key of the crankshaft. Tighten the pulley bolt to the specified torque.
