11. Remove the crankshaft bearing cap bolts and the
caps.
12. Measure the width of the flattened plastic thread of
the plastic gauging using a ruler. (Plastic gauging is
available for different tolerance ranges.)
13. Inspect the bearing clearance for permissible toler-
ance ranges. Refer to ”Engine Specifications”in this
section.
14. Apply a bead of adhesive sealing compound to the
grooves of the crankshaft bearing caps.
15. Install the crankshaft bearing caps to the engine
block.
16. Tighten the crankshaft bearing caps using new
bolts.
Tighten
Tighten the crankshaft bearing cap bolts to 15 NSm
(26 lb–ft). Use the angular torque gauge, KM–470–B,
to tighten the crankshaft bearings +45 degrees +
another 15 degrees.
Important : Grease the connecting rod journals and lubri-
cate the connecting rod bearings slightly so that the plastic
gauging thread does not tear when the connecting rod
bearing caps are removed.
17. Inspect all of the connecting rod bearing clearances
using a commercially available plastic gauging
(ductile plastic threads).
18. Cut the plastic gauging threads to the length of the
connecting rod bearing width. Lay them axially be-
tween the connecting rod journals and the connect-
ing rod bearings.
19. Install the connecting rod bearing caps.
Tighten
Tighten the connecting rod bearing cap bolts to 35
NSm (26 lb–ft). Use the angular torque gauge
KM–470–B to tighten the connecting rod bearing cap
bolts to +45 degrees plus one turn of 15 degrees.
