Big-end bearings
1. Lubricate big-end bearing shells and
crankshaft journals with engine oil.
2. Fit numbers 1 and 4 big-end bearing caps and
shells, fit bearing cap nuts and tighten to 59
Nm.
3. Move numbers 1 and 4 connecting rods fully to
one side of crankshaft journal and using feeler
gauges, check end-float of both connecting
rods on journals is between 0.15 and 0.35 mm.
4. If end-float is outside limits, replace connecting
rod.
5. Check that crankshaft rotates smoothly.
