Connecting Rod and Crankshaft
End Play
1. Measure the connecting rod end play with a feeler
gauge.
Connecting Rod End Play:
Stsndard (Nsw): 0.15 - 0.30 mm
{0.006 - 0.012 in)
Service Limit: 0./t0 mm 10.016 in)
2. lf the connecting rod end play is out-of-tolerance,
install a new connecting rod.
lf it is still out-of-tolerance, replace the crankshaft
{see pages 7-9 and 7-20).

3. Push the crankshaft firmly away from the dial indi-
cator, and zero the dial against the end of the
crankshaft. Then pull the crankshaft firmly back
toward the indicator; the dial reading should not
exceed the service limit.
Crankshaft End Play:
Stand.rd (New): 0.10 - 0,35 mm(0.004 - 0.014 inl
Service Limit: 0.45 mm (0.018 inl
4. lf end play is excessive, inspect the thrust washers
and thrust surface on the crankshaft. Reolace oans as
necessary. Thrust washer thickness is fixed and
must not be changed either by grinding or shim-
mrng.

Clearance
To check main bearing-to-journal oil clearance,
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place a strip of plastigage across each main journal.
NOTE: lf the engine is still in the vehicle when you
bolt the main cap down to check clearance, the
weight of the crankshaft and flywheel will flatten
the plastigage further than just the torque on the
cap bolt, and give you an incorrect reading. For an
accurale reading, support the crank with a jack
under the counterweights and check only one bear-
Ing aI a Irme.
Reinstall the bearings and caps, then torque the
bolts,

Remove the bearing cap again, and measure the

lf the plastigage measures too wide or too narrow,(remove the engine if it's still in the vehicle),
remove the crankshaft, and remove the upper half
of the bearing. Install a new, complete bearing with
the same color code (select the color as shown on
the next page). and recheck the clearance, Do not
file, shim, or scrape the bearings or the caps to
adjust the clearance.
lf the plastjgage shows the clearance is still incor-
rect, try the ne)d larger or smaller bearing {the color
listed above or below that one), and check again. lf
the proper clearance cannot be obtained by using
the appropriate larger or smaller bearings, replace
the crankshaft and start over.

lf you can feel a ridge of metal or hard carbon
around the top of each cvlinder, remove it with a
ridge reamer. Follow the reamer manufacturer's
instructions. lf the ridge is not removed, it may

removing each piston/connecting rod assembly.
To avoid mixup on reassembly, mark each piston/
connecting rod assembly with its cylinder number.
NOTE: The existing number on the connecting rod
does not indicate its position in the engine, it indi-
cates the rod bore size.
