Using a screwdriver, install a new snap ring at one end of the piston pin hole.

УКАЗАНИЕ:

Make sure that the end gap of the snap ring is not aligned with the pin hole cutout portion of the piston.

Gradually heat the piston to approximately 80 to 90°C (176 to 194°F).

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

УКАЗАНИЕ:

The piston and pin are a matched set.

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

УКАЗАНИЕ:

Make sure that the end gap of the snap ring is not aligned with the pin hole cutout portion of the piston.

Check the fitting condition between the piston and piston pin by trying to move the piston back and forth on the piston pin.

Install the oil ring expander and oil ring rail by hand.

ПРИМЕЧАНИЕ:

1. Install the expander and oil ring so that their ring ends are at opposite sides.
   
2. Securely install the expander to the inner groove of the oil ring.
   

Using a piston ring expander, install the 2 compression rings so that the paint marks are positioned as shown in the illustration.

ПРИМЕЧАНИЕ:

1. Install the compression ring No. 1 with the code mark (T) facing upward.
   
2. Install the compression ring No. 2 with the code mark (2T) facing upward.
   
3. Paint marks can only be checked on new piston rings. When reusing piston rings, check each piston ring profile in order to install them into the correct positions.
   

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

Install the upper bearing (for except No. 3 journal).

1. Install the upper bearing with an oil groove on the cylinder block.
   

2. Using scale, measure the distance between the cylinder block edge and the upper bearing's edge.
   

   ПРИМЕЧАНИЕ:

   Do not apply engine oil to the bearings or the contact surfaces.

   Dimension (A):

   0.5 to 1.0 mm (0.020 to 0.039 in.)
   

Install the upper bearing (for No. 3 journal).

1. Install the upper bearing with an oil groove on the cylinder block.
   

2. Using vernier calipers, measure the distance between the cylinder block edge and the upper bearing's edge.
   

   ПРИМЕЧАНИЕ:

   Do not apply engine oil to the bearings or the contact surfaces.

   Dimension (A - B):

   0.7 mm (0.0276 in.) or less
   

Install the lower bearing.

1. Install the lower bearing onto the bearing cap.
   





2. Using vernier calipers, measure the distance between the bearing cap's edge and the lower bearing's edge.
   

   Dimension (A - B):

   0.7 mm (0.0276 in.) or less
   

   ПРИМЕЧАНИЕ:

   Do not apply engine oil to the bearings or the contact surfaces.

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

Apply engine oil to the crankshaft thrust washer.

Apply engine oil to the upper bearing and install the crankshaft on the cylinder block.

Apply engine oil to the lower bearing.

Examine the number marks and install the bearing caps on the cylinder block.

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

Temporarily install the 10 main bearing cap bolts.

Insert the main bearing cap with your hand until the clearance between the main bearing cap and the cylinder block is less than 5 mm (0.20 in.) by marking the 2 internal bearing cap bolts as a guide.

Using a plastic hammer, lightly tap the bearing cap to ensure a proper fit.

Install the crankshaft bearing cap bolts.

ПРИМЕЧАНИЕ:

The main bearing cap bolts are tightened in 2 progressive steps.

Step 1

1. Install and uniformly tighten the 10 main bearing cap bolts in the sequence shown in the illustration.
   

   Момент затяжки:

   40 Н*м{408 кгс*см, 30 фунт-сила-футов}

Step 2

1. Mark the front of the bearing cap bolts with paint.
   

2. Further tighten the bearing cap bolts by 90° in the numerical order shown in the previous illustration.
   

Check that the paint mark is now at a 90° angle to the front.

Check that the crankshaft turns smoothly.

Check the crankshaft thrust clearance (See page Нажмите здесь).

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

Using vernier calipers, measure the distance between the connecting rod's and bearing cap's edges and the connecting rod bearing's edge.

Dimension (A - B):

0.7 mm (0.0276 in.) or less

ПРИМЕЧАНИЕ:

Do not apply engine oil to the bearings or the contact surfaces.

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

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

ПРИМЕЧАНИЕ:

Do not align the 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.

ПРИМЕЧАНИЕ:

1. When inserting the piston with connecting rod, do not allow it to make contact with the oil nozzle.
   
2. Match the numbered connecting rod cap with the connecting rod.
   

Check that the protrusion of the connecting rod cap is facing in the correct direction.

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

Install the connecting cap bolts.

ПРИМЕЧАНИЕ:

The connecting cap bolts should be tightened in 2 progressive steps.

Step 1

1. Using SST, install and alternately tighten the bolts of the connecting rod cap in several steps.
