Cylinder Block (W/ Glow Plug Controller) Reassembly

Install the stud bolts.

Align the pin of the No. 1 oil nozzle with the pin hole of the cylinder block.

Install the 4 No. 1 oil nozzles with the 4 check valves.

Torque:

26 N*m{265 kgf*cm, 19 ft.*lbf}

Using a small screwdriver, install a new snap ring on one side of the piston pin hole.

Gradually heat the piston to approximately 80°C (176°F).

Coat the piston pin with engine oil.

Align the front marks of the piston and connecting rod, connect the connecting rod to the piston, and then push in the piston pin with your thumb.

Check the fit between the piston and piston pin. Try to move the piston back and forth on the piston pin.

Using a small screwdriver, install a new snap ring on the other side of the piston pin hole.

Install the coil and oil ring by hand.

HINT:

Make sure the end gap of the oil ring and the coil joint are on opposite sides.

Using a piston ring expander, install the No. 1 and No. 2 piston rings with the code marks facing upward.

Code Mark:

Ring	Code Mark
No. 1 Piston Ring	NAC
No. 2 Piston Ring	KD1

Position the piston rings so that the ring ends are as shown in the illustration.

NOTICE:

Do not align the ring ends.

Align the bearing claw with the claw groove of the cylinder block and push in the 5 upper bearings.

Align the bearing claw with the claw groove of the crankshaft bearing cap and push in the 5 lower bearings.

Place the crankshaft on the cylinder block.

Push the crankshaft in one direction and install one thrust washer to the No. 5 journal position with the oil groove facing outward.

Push the crankshaft in the opposite direction and install the other thrust washer to the No. 5 journal position with the oil groove facing outward.

Install the 2 thrust washers to the No. 5 bearing cap with the grooves facing outward.

Install the 5 crankshaft bearing caps to their proper locations.

Install the crankshaft bearing cap bolts.

HINT:

1. The crankshaft bearing cap bolts are tightened in 2 progressive steps.
   
2. If a crankshaft bearing cap bolt is broken or deformed, replace it.
   

1. Apply a light coat of engine oil to the threads and under the bolt heads of the crankshaft bearing cap bolts.
   

2. Install and uniformly tighten the 10 bolts of the crankshaft bearing caps in several passes in the sequence shown in the illustration.
   

   Torque:

   50 N*m{510 kgf*cm, 37 ft.*lbf}

   If any one of the bearing cap bolts does not meet the torque specification, replace the bearing cap bolt.
   




3. Mark the front of each crankshaft bearing cap bolt with paint.

4. Tighten the crankshaft bearing cap bolts by 90° in the numerical order shown in the previous illustration.
   

5. Check that the painted marks are now at a 90° angle to the front.
   

Check that the crankshaft turns smoothly.

Check the crankshaft thrust clearance.

Align the bearing claw with the groove of the connecting rod or connecting rod cap.

Install the bearings to the connecting rod and connecting rod cap.

Using a dial indicator, measure the thrust clearance while prying the crankshaft back and forth with a screwdriver.

Standard thrust clearance:

0.04 to 0.24 mm (0.00157 to 0.00945 in.)

Maximum thrust clearance:

0.3 mm (0.0118 in.)

Standard Thrust Washer Thickness:

Item	Specified Condition
STD	2.430 to 2.480 mm (0.0957 to 0.0976 in.)
O/S 0.125	2.555 to 2.605 mm (0.1006 to 0.1026 in.)
O/S 0.250	2.680 to 2.730 mm (0.1055 to 0.1074 in.)

Apply engine oil to the cylinder walls, the pistons and the surfaces of the connecting rod bearings.

Check the positions of the piston ring ends.

Using a piston ring compressor, push the correctly numbered piston and connecting rod assembly into the cylinder with the front mark of the piston facing forward.

Place the connecting rod cap on the connecting rod.

1. Match each numbered connecting rod cap with the correct connecting rod.
   

2. Align the pins of the connecting rod cap with the pin holes of the connecting rod and install the connecting rod cap.
   





3. Check that the front mark of the connecting rod cap is facing forward.

Install the connecting rod cap bolts.

HINT:

1. The connecting rod cap bolts are tightened in 2 progressive steps.
   
2. If any connecting rod bolt is broken or deformed, replace it.
   

1. Apply a light coat of engine oil to the threads and under the heads of the connecting rod cap bolts.
   

2. Install and alternately tighten the bolts of the connecting rod cap in several passes.
   

   Torque:

   35 N*m{357 kgf*cm, 26 ft.*lbf}

   HINT:

   If any one of the connecting rod cap bolts does not meet the torque specification, replace the cap bolt.





3. Mark the front of each connecting rod cap bolt with paint.

4. Tighten the connecting rod cap bolts by 90° as shown in the illustration.
   

5. Check that the painted marks are now at a 90° angle to the front.
   

Check that the crankshaft turns smoothly.

Using a dial indicator, measure the thrust clearance while moving the connecting rod back and forth.

Standard thrust clearance:

0.100 to 0.300 mm (0.00394 to 0.0118 in.)

Maximum thrust clearance:

0.40 mm (0.0157 in.)
