Always use new connecting rod cap bolts. Connecting rod cap
bolts are toque-to-yield bolts designed to be permanently elongated
beyond the state of elasticity when torqued, so if the bolts are removed
and reused, it may cause the bolts to break or fail to maintain
clamping force.
•
Do not turn the crankshaft.
(7)
Remove 2 bolts, connecting rod cap and bearing half.
(8)
Measure the plastigage at its widest point.
Standard oil clearance
0.031 ~ 0.045mm (0.00122 ~ 0.00177in.)
(9)
If the plastigage measures too wide or too narrow, remove the
upper half of the bearing, install a new, complete bearing with the
same color mark (select the color as shown in the next column), and
recheck the clearance.
Do not file, shim, or scrape the bearings or the caps to adjust clearance.
(10)
If the plastigage shows the clearance is still incorrect, try
the next larger or smaller bearing (the color listed above or below
that one), and check clearance again.
•
If the proper clearance cannot be obtained by using the
appropriate larger or smaller bearings, replace the crankshaft and start
over.
•
If the marks are indecipherable because of an accumulation of
dirt and dust, do not scrub them with a wire brush or scraper. Clean
them only with solvent or detergent.

Inspect the connecting rods.
(1)
When reinstalling, make sure that cylinder numbers put on the
connecting rod and cap at disassembly match. When a new connecting rod
is installed, make sure that the notches for holding the bearing in
place are on the same side.
(2)
Replace the connecting rod if it is damaged on the thrust
faces at either end. Also if step wear or a severely rough surface of
the inside diameter of the small end is apparent, the rod must be
replaced as well.
(3)
Using a connecting rod aligning tool, check the rod for bend
and twist. If the measured value is close to the repair limit, correct
the rod by a press. Any connecting rod that has been severely bent or
distorted should be replaced.
Allowable bend of connecting rod :
0.05mm (0.0020 in.) or less for 100mm (3.94 in.)
Allowable twist of connecting rod :
0.10mm (0.0039 in.) or less for 100mm (3.94 in.)
Crankshaft
1.
Check the crankshaft bearing oil clearance.
(1)
To check main bearing-to-journal oil clearance, remove the main caps and bearing halves.
(2)
Clean each main journal and bearing half with a clean shop towel.
(3)
Place one strip of plastigage across each main journal.
(4)
Reinstall the bearings and caps, then torque the bolts.
Always use new crankshaft main bearing cap bolts. Crankshaft
main bearing cap bolts are toque-to-yield bolts designed to be
permanently elongated beyond the state of elasticity when torqued, so if
the bolts are removed and reused, it may cause the bolts to break or
fail to maintain clamping force.
•
Do not turn the crankshaft.
(5)
Remove the cap and bearing again, and measure the widest part of the plastigage.
Standard oil clearance
0.020 ~ 0.038mm (0.00079 ~ 0.00150in.)
(6)
If the plastigage measures too wide or too narrow, remove the
upper half of the bearing, install a new, complete bearing with the
same color mark (select the color as shown in the next column), and
recheck the clearance.
Do not file, shim, or scrape the bearings or the caps to adjust clearance.
(7)
If the plastigage shows the clearance is still incorrect, try
the next larger or smaller bearing (the color listed above or below
that one), and check clearance again.

If the proper clearance cannot be obtained by using the
appropriate larger or smaller bearings, replace the crankshaft and start

If the marks are indecipherable because of an accumulation of
dirt and dust, do not scrub them with a wire brush or scraper. Clean
them only with solvent or detergent.

Letters have been stamped on the block as a mark for the size of each of the 5 main journal bores.
Use them, and the numbers or bar stamped on the crank (marks for main journal size), to choose the correct bearings.
