28. Remove the connecting rod bearing cap.
29. Install the piston.
30. Rotate the crankshaft by hand and check whether it rotates
smoothly.
31. If the bearings are damaged,
- replace the oil presser relief valve.
- clean the oil pump and oil filter housing carefully and
replace the hose if necessary.
Notice
After assembling the engine, check the camshaft timing,
adjust the start of fuel injection and check the TDC sensor
bracket setting.
32. Fill oil and run the engine and then check the oil pressure
and oil level.
Notice
Install the original oil filter element and then change the
engine oil and oil filter element after 1,000 - 1,500km. 27. Measure the radial clearance (L) of the connecting rod
bearing.
Example)Measured value ‘J’ = 47.700mm
Measured value ‘K’ = 47.653mm
Clearance ‘L’ = 0.047mm
Radial Clearance ‘L’ 0.026 - 0.068mm
Notice
If the clearance is out of standard, adjust the radial
clearance of connecting rod bearing by replacing the
connecting rod bearing shells. 26. Measure connecting rod bearing journal diameter (K).
Notice
Refer to measurement of the crankshaft bearing journal
diameter.
24. Insert the new connecting rod bearing shells into the
connecting rod and connecting rod bearing cap and tighten
the 12-sided stretch bolts (11).
25. Measure inner diameter of connecting rod bearing.

5A-126 AUTOMATIC TRANSMISSION
Oil Filter and Pan Assembly
Notice
1. Replace the filter whenever rebuilding a transmission where a significant amount of mechanical damage has
occurred.
2. To aid the assembly of the pan gasket, use a small amount of Vaseline at the pan/gasket interface. This ensures
that the gasket remains on the pan ridge. Do not over torque pan bolts as this may distort the pan and cause
leaks.
3. Ensure that the internal line pressure plus in the valve body is fitted.
To assemble the oil filter and pan assembly (refer to figures 8.63 and 8.64), proceed as follows.
1. Lubricate the oil filter sealing ring with automatic transmission fluid.
2. Carefully assemble the oil filter to the valve body. The spigot must not lean on one side while being fitted. Refer to
figure 8.63.
3. Secure the oil falter assembly with the retainer.
4. Check that the magnet is located in the dimple in the comer of the oil pan.
5. Assemble the gasket on the pan lip. The gasket must be free of any distortion when installed.
6. Fit the oil pan assembly to the transmission case and tighten the securing bolts to specification and sequence
(refer to figure 8.65). Do not over torque.

5D2-48 TRANSFER CASE (TOD)
6. Install the front planet to the sun gear and input shaft.
Install the internal snap ring to the planetary carrier.
7. Place the tanged snap ring in the case. Expand snap ring
with snap ring pliers and install planetary carrier assembly.
Check installation by holding the case and carefully tapping
the face of the input shaft against a wooden block to make
sure the snap ring is installed.
8. Remove all traces of gasket sealant from the front case
and mounting adapter mating surfaces. Install a bead of
gasket sealant on the surface of the front case.
9. Install the high-low shift fork and high-low collar as an
assembly into the front planet.
Notice
Make sure that the nylon wear pads are installed on the
shift fork and snapped securely into place.

10. If new pump is used, align the flat of the output shaft and
the flat of the pump. Slide the pump onto the output shaft.
lDo not disassemble oil pump. It is serviced only as an
assembly. Check the pump to make sure the pump
rotates freely.
lDo not remove the plastic insert from the bore of the
new pump. Discard it after it slides out during pump
installation to the rear output shaft.
lWhile turning the output shaft, prime the pump through
the oil filter pickup tube or housing inlet hole with clean
Automatic Transmission Fluid or equivalent.
11. Inspect the outside surfaces and bore of the oil pump. If
there is no discoloration in the pump housing, gear or cover,
and the pump bore and the lube holes of the output shaft
show evidence of oil, the pump is working.
