ENGINE MECHANICAL 6A – 85
3. Measure the oil clearance between the connecting
rod and the crankshaft.
1) Remove the connecting rod cap nuts and the
rod caps.
Arrange the removed rod caps in the cylinder
number order.
2) Clean the rod bearings and the crankshaft pins.
3) Carefully check the rod bearings.
If even one bearing is found to be damaged or
badly worn, the entire bearing assembly must be
replaced as a set. Reinstall the bearings in their
original positions.
Apply plastigage to the crank pin.
4) Reinstall the rod caps to their original positions.
5) Tighten the cap nuts in 2 steps, using angular
tightening method as shown in the following
specifications.
1st step: 29 Nꞏm (3.0 kgꞏm/22 lb ft)
2nd step: 45°– 60°NOTE: Do not allow the crankshaft to rotate
6) Remove the rod caps.
7) Measure the smallest width of the plastigage
and determine the oil clearance. If the oil
clearance exceeds the limit, replace the rod
bearings as a set.
8) Clean the plastigage from the bearings and the
crankshaft pins
Standard: 0.022 – 0.042 mm (0.0009 – 0.0017 in)
Limit: 0.100 mm (0.0039 in)
REASSEMBLY
1. Connecting Rod
2. Piston
3. Piston Pin
1) Apply a coat of engine oil to the piston pin and
the piston pin hole.
4. Piston Pin Snap Ring
1) Try to insert the piston pin into the piston pin
hole with normal finger pressure.
2) Weight each piston and connecting rod
assembly.
3) Select piston and connecting rod combinations
so that the weight variation of the different four
assemblies is held within the specified limits.
Variance in weight after assembly: Less than 3g
(0.1058 oz)
NOTE: When changing piston/connecting rod
combinations, do not change the piston/piston pin
combination.
4) Attach the piston to the connecting rod with the
piston front mark (2) and the connecting rod
front mark (3) on the same side.

38. Overdrive clutch end play measurement.
1. Fit 5–8840–2271–0 (J–25022) and
5–8840–0618–0 (J–24773–1) turbine shaft puller
on turbine shaft.
2. Position axial play checking tool on converter
housing mating face.
3. Pull turbine shaft upwards with puller until first
resistance is met. (due to weight of overdrive
assembly).
4. Maintain shaft in this position and set indicator to
zero.
5. Pull turbine shaft further upwards with puller.
Read end play shown on indicator.
End play: 0.1mm – 0.8mm (0.004 in – 0.031in)6. Remove axial play checking tool and puller.
NOTE: If end play is not correct, repeat selective washer
selection.

39. Inspect extension housing oil seal and replace if
necessary, using 5–8840–2282–0 (J–36797)
extension housing oil seal installer.
Rotate transmission to horizontal position, with
valve body side down.
Inspect parking wheel seal ring. Replace if
necessary.
Install wheel parking lock assembly (35).
40. Install speed wheel (36) and snap ring (37).
NOTE: Use extra long, needle-nose pliers.
41. Install gasket onto extension assembly with a thin
coating of oil.
Install extension housing assembly (38), and align
parking pawl shaft.
Install actuator assembly into extension assembly.
Install seven 8 mm hexagon socket head screws.
To r q u e : 3 2 N

42. Inspect speed sensor O–ring. Replace if necessary.
Install speed sensor assembly (39) and 10 mm
screw.
