Cylinder Block Assembly: Specifications







Installing crankshaft bearing cap
^ Replace bolts A and nuts -1- to -8-.
^ Inserting alignment bushings into cylinder block
^ Tighten bearing cap nuts or bolts in the following sequence:
1. - Screw in bolts -A- hand tight.
2. - Tighten nuts -1- to -8- to 35 Nm.
3. - Tighten nuts -1- to -8- 90° (1/4 turn) further using rigid wrench.
4. - tighten bolts -A- to 20 Nm.
5. - Tighten bolts -A- 90° (1/4 turn) further using rigid wrench.

Connecting rod bolt 30 Nm + 90° (1/4 additional turn)

Harmonic balancer to crankshaft 23 Nm
Vibration damper/pulley at crankshaft 10 Nm + 90° 2)3)
2) Replace bolts
3) 90° equals one quarter turn








Checking piston ring end gap
^ Insert ring at a right angle to cylinder wall from above to lower cylinder opening approximately 15 mm cylinder edge. When inserting use pistons without rings








Checking piston ring side clearance
^ Before measuring] clean piston ring groove

Checking pistons
Special Tools and Equipment





^ External micrometer 75-100 mm
^ Measure approximately 10 mm from the lower edge at a 90° angle to piston pin axis.
^ Deviation from nominal dimension: maximum 0.04 mm
Specified dimension, Refer to Piston piston and cylinder measurements





Piston installed position and allocation piston/cylinder
^ Mark installed position and allocation to cylinder on piston head using chalk or water-proof felt pen.

Note: Do not use a center punch or scribe, since the piston head coating will be damaged.

^ Installation position:
Arrow on piston head points to belt pulley side





Piston and cylinder measurements
1) Dimensions exclude graphite coating (thickness 0 02 mm). The graphite coating wears off.
