HINT:

1. After tightening the drain cock to the specified torque, rotate the drain union clockwise until its drain port is facing downward.
   
2. The drain port may be set within 45° of either side of the prescribed position.
   

Using a 6 mm hexagon socket wrench, install the oil orifice.

Torque:

11 N*m{110 kgf*cm, 8 ft.*lbf}

Align the pin of the oil nozzle with the one of the pin holes of the cylinder block.

Install the oil nozzle with the check valve.

Torque:

26 N*m{260 kgf*cm, 19 ft.*lbf}

Assemble the piston and connecting rod.

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

2. Gradually heat the piston to about 60°C (140°F).
   

3. Coat the piston pin with engine oil.
   





4. 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.

   HINT:

   Make sure the end gap of the oil ring faces the opposite direction of the coil joint.





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

   Code Mark:

   Item	Code Mark
   No. 1 piston ring	1N
   No. 2 piston ring	2N

   NOTICE:

   Do not align the ring ends.

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.

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

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

Install the 2 thrust washers to the No. 3 journal position of the cylinder block with the oil grooves facing outward.

Install the 2 thrust washers to the No. 3 crankshaft bearing cap with the grooves facing outward.

Place the crankshaft on the cylinder block.

Install the 5 crankshaft bearing caps in their proper locations.

Install the crankshaft bearing cap bolts.

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





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

   Torque:

   105 N*m{1071 kgf*cm, 77 ft.*lbf}

Check that the crankshaft turns smoothly.

Check the crankshaft thrust clearance (LandCruiser RM00000125A064X_01_0107.html).

Cover the connecting rod bolts with a short piece of hose to protect the crankshaft and cylinder bore from damage.

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. Install the connection rod cap with the front mark facing forward.

Install the connecting rod cap nuts.

NOTICE:

If any connecting rod bolt is broken or deformed, replace it.

HINT:

The connecting rod cap nuts are tightened in 2 progressive steps.

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

Step 1:

1. Install and alternately tighten the nuts of the connecting rod cap in several passes.
   

   Torque:

   54 N*m{551 kgf*cm, 40 ft.*lbf}

   HINT:

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

Step 2:

1. Mark the front side of the connecting rod cap nuts with paint.
   

2. Tighten the connecting rod cap nuts 90° in the shown step 1.
   

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

Check that the crankshaft turns smoothly.

Check the connecting rod thrust clearance (LandCruiser RM00000125A064X_01_0103.html).
