Connecting Rod and Crankshaft End Play Inspection
1.Remove the oil pump (see page 8-9).
Remove the baffle plates (see step 6 on page 1 -12).
3. Measure the connecting rod end play with a feeler
gauge between the connecting rod and crankshaft.
Connecting Rod End Play
Standard {New): 0.15 0.30 mm(0.006-0.012 in.l
Service Limit 0.40 mm (0.016 in.l
4.lf the connecting rod end play is out-of-tolerance,
install a new connecting rod, and recheck. lf it is
still out-of-tolerance, replace the crankshaft (see
page 7 -12],.
5. lnstall a dial indicator as shown. Push the
crankshaft firmly away from the dial indicator, 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 Plav
Standard lNew): 0.10-0.35 mm
{0.004-0.014 in.l
Service Limit: 0.45 mm {0.018 in.)
lf the end play is out-of-tolerance, replace the thrust
washers and recheck. lf it is still out-of-tolerance,
replace the crankshaft.

Engine Block
Crankshaft Main Bearing Replacement
Main Bearing Clearance Inspection
1. To check main bea ring-to-jou rna I oil clearance.
remove the lower block and bearing halves (see
page 1 -12)..
2, Clean each main journal and bearing half witha
clean shop towel.
3. Place one strip of plastigage across each main
lou rnal.
4. Reinstallthe bearings and lower block, then torque
the bolts to 29 N.m {3.0 kgf.m,22 lbf.ft) + 56'.
NOTE: Do not rotate the crankshaft during
Inspeclton.
5. Remove the lower block and bearings again, and
measure the widest part of the plastigage.
Main Bearing-to-Journal Oil Clearance
No. 1,2, 4,5 Journals:
Standard (New): 0.017 0.041 mm
Service Limit:
No.3 Journal:
10.0007 0.0016 in.l
0.050 mm {0.0020 in.)
Standard {Newl: 0.025 - 0.049 mm(0.0010 0.0019 in.)
Service Limit: 0.055 mm (0.0022 in.l

\.
6. lf the plastigage measures too wide or too narrow,
remove the crankshaft. and remove the upper half
ofthe bearing. Install a new, complete bearing with
the same color code{s), and recheck the clearance.
Do not file, shim, or scrape the bearings or the caps
to adjust clearance.
7. lf 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
again. lf the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.
