7. DETERMINE ROD BEARING CLEARANCE.
Bearing clearance = Rod inside diameter minus
crankshaft journal diameter.
Clearance = .0035 in. (.009 mm)
Bearing clearance can also be
8. CHECK PISTON RING GAP.
determined using Plastigage during
a. Determine proper ring set according to piston
diameter measurement taken in step 2.
a. Install bearings (4) and rod caps (2). Install nuts
(3) and tighten to 73 ft-lbs (99 Nm). Measure
and record smallest diameter.
Rings for a turbocharged engine are
same as rings for a naturally
b. Position each ring in cylinder and use a piston to
square it in bore 3.5 in. (89 mm) from top of
block. Use feeler gauge to measure ring gap.
b. Measure and record maximum diameter of
appropriate rod journal on crankshaft.
Min. dia. = 2.9906 in. (75.962)
Max. dia. = 2.9921 in. (76.000)
Out-of-roundness = .002 in.
Tapers = .0005 in.
