8. CHECK CRANKSHAFT THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance
while prying the crankshaft back and forth with a
screwdriver.
Standard thrust clearance:
0.020 ± 0.220 mm (0.0008 ± 0.0087 in.)
Maximum thrust clearance:
0.30 mm l0.0118 in.)
If the thrust clearance is greater than maximum, re±
place the thrust washers as a set.
Thrust washer thickness:
2.440 ± 2.490 mm 10.0961 ± 0.0980 in.)
(b) Using the removed main bearing cap bolts, pry the
main bearing cap back and forth, and remove the main
bearing caps, lower bearings and lower thrust wash±
ers (No.3 main bearing cap only).
HINT:
wKeep the lower bearing and main bearing cap
together.
wArrange the main bearing caps and lower thrust
washers in correct order. HINT:
wKeep the bearings, connecting rod and cap to±
gether.
wArrange the piston and connecting rod assembl±
ies in correct order.
9. REMOVE MAIN BEARING CAPS AND CHECK OIL

HINT: If replacing the cylinder block subassembly, the
bearing standard clearance will be:

having the same number. If the number of the bearing
cannot be determined, select the correct bearing by
adding together the numbers imprinted on the cylin±
