ENGINE MECHANICAL CYLINDER BLOCK
EM−87
1996 LAND CRUISER (RM451U)
Standard sized bearing center wall thickness:
Mark ”2”1.744 − 1.747 mm (0.0687 − 0.0688 in.)
Mark ”3”1.747 − 1.750 mm (0.0688 − 0.0689 in.)
Mark ”4”1.750 − 1.753 mm (0.0689 − 0.0690 in.)
Mark ”5”1.753 − 1.756 mm (0.0690 − 0.0691 in.)
Mark ”6”1.756 − 1.759 mm (0.0691 − 0.0693 in.)
(k) Completely remove the Plastigage.
15. R E M O V E P I S TO N A N D C O N N E C T I N G R O D A S-
SEMBLIES
(a) Using a ridge reamer, remove the all carbon from the top of the cylinder.
(b) Push the piston, connecting rod assembly and upper bearing through the top of the cylinder block.
HINT:
Keep the bearings, connecting rod and cap together.
Arrange the piston and connecting rod assemblies in cor-
rect order.
16. 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 (0.0118 in.)
If the thrust clearance is greater than maximum, replace the
thrust washers as a set. Thrust washer thickness:
STD2.440 − 2.490 mm (0.0961 − 0.0980 in.)
O/S 0.1252.503 − 2.553 mm (0.0985 − 0.1005 in.)
O/S 0.2502.565 − 2.615 mm (0.1010 − 0.1030 in.)
17. REMOVE MAIN BEARING CAPS AND CHECK OIL
CLEARANCE
(a) Uniformly loosen and remove the main bearing cap bolts
in several passes, in the sequence shown.

ENGINE MECHANICAL CYLINDER BLOCK
1996 LAND CRUISER (RM451U)
HINT:
If the location of this area cannot be judged by visual inspection,
measure the outer diameter at the location shown in the illustra-
tion.
If the outside diameter is less than minimum, replace the con-
necting rod bolt and nut as a set.
6. INSPECT CRANKSHAFT
(a) Inspect for circle runout. (1) Place the crankshaft on V−blocks.
(2) Using a dial indicator, measure the circle runout atthe center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
(b) Inspect the main journals and crank pins. (1) Using a micrometer, measure the diameter of each
main journal and crank pin.
Main journal diameter:
STD68.982 − 69.000 mm (2.7158 − 2.7165 in.)
U/S 0.2568.745 − 68.755 mm (2.7065 − 2.7069 in.)
Crank pin diameter:
STD56.982 − 57.000 mm (2.2434 − 2.2441 in.)
U/S 0.2556.745 − 56.755 mm (2.2341 − 2.2344 in.)
If the diameter is not as specified, check the oil clearance (See
page EM−83 ). If necessary, grind or replace the crankshaft.
(2) Check each main journal and crank pin for taper and out−of−round as shown.
Maximum taper and out−of−round:
0.02 mm (0.0008 in.)
If the taper and out −of− round is greater than maximum, replace
the crankshaft.
7. IF NECESSARY, GRIND AND HONE MAIN JOURNALS
AND/OR CRANK PINS
Grind and hone the main journals and/or crank pins to the fin-
ished undersized diameter. Install new main journal and/or
crankshaft pin undersized bearings.
