2.4 BSM

The key of crankshaft should be aligned with the mating face of main bearing cap. As a result of this, the piston of No. 1 cylinder is placed at the top dead center on compression stroke.
Confirm the balance shaft module timing mark.
Timing marks to be visually aligned with centers of adjacent cast timing notches.

TIGHTENING ORDER

4 Bolts TYPE
1. Tighten the bolts in order number as shown with seating torque 25.5 N.m (2.6 kgf.m, 18.8 lb-ft) and then loosen the bolts as reverse tightening order (4-3-2-1).
2. Using the SST (09221-4A000), tighten the bolts as specified tightening order in same increments as follows.
Tightening torque:

M8*179 : 14.7 ~ 18.6 N.m (1.5 ~ 1.9 kgf.m, 10.8 ~ 13.7 lb-ft) + 58 ~ 62° + 58 ~ 62°

M9*181.5 : 22.6 ~ 26.5 N.m (2.3 ~ 2.7 kgf.m, 16.6 ~ 19.5 lb-ft) + 103° ~ 107°
