Assembly

Always use new gaskets, sealing rings, sealing wash-

ers and lock-washers. Coat the sealings with grease

or oil them and also oil all moving parts prior to install-

ing them.

1. Heat the crankshaft gear wheel to approx. 150°C

(302°F) prior to the installation. Place the key in the

key-way of the crankshaft and press on the gear

wheel. Oil the new main bearing halves (with oil hole)

and install them in the block. Put in the crankshaft.

NOTE! The main bearing shell at the flywheel also

functions as a thrust-bearing.

2. Oil the cap bearing halves and install them. Install

the caps in accordance with the marking in the block

(2001 has no intermediate bearing). If an arrow is

cast, it shall point towards the oil dipstick. Tightening

torque for the main bearings: 1st tightening 20 Nm

(14.7 ft.lbs), 2nd tightening 60 Nm (44.2 ft.lbs). Turn

the engine.

3. Turn the piston rings so that the piston ring gaps

are displaced in relation to each other. The top of the

piston is marked with an arrow, which is to be directed

towards the front of the engine. Use installation ring p/

n 884813. Install the caps with the marking coinciding

with that of the connecting rod. The connecting rod

can be turned on the piston at your own discretion.

Tightening torque: 70 Nm (51.6 ft.lbs).

4. Install the main bearing halves in the oil pan and

coat the edge of the oil pan with thin layer of sealing

compound p/n 840879. Install the oil pan and tighten

the oil pan screws and the main bearing screws alter-

natingly to 20 Nm (14.7 ft.lbs.) and then the main

bearing screws to 60 Nm (44.2 ft.lbs.).
