1999 NISSAN PICK-UP height

The limit of cylinder head resurfacing is determined by the
cylinder block resurfacing.
Amount of cylinder head resurfacing is ªAº.
Amount of cylinder block resurfacing is ªBº.
The maximum limit:
A+B=0.2mm(0.008 in)
After resurfacing cylinder head, check that camshaft rotates
freely by hand. If resistance is felt, cylinder head must be
replaced.
Nominal cylinder head height:
126.3 - 126.5 mm (4.972 - 4.980 in)
CAMSHAFT VISUAL CHECK
Check camshaft for scratches, seizure and wear.
CAMSHAFT RUNOUT
1. Measure camshaft runout at the center journal.
Runout (Total indicator reading):
Standard
Less than 0.02 mm (0.0008 in)
Limit
0.04 mm (0.0016 in)
2. If it exceeds the limit, replace camshaft.
CAMSHAFT CAM HEIGHT
1. Measure camshaft cam height.
Standard cam height:
Intake 42.505 - 42.695 mm (1.673 - 1.681 in)
Exhaust 40.905 - 41.095 mm (1.610 - 1.618 in)
Cam height wear limit:
Intake & Exhaust
0.2 mm (0.008 in)
2. If wear is beyond the limit, replace camshaft.
CAMSHAFT JOURNAL CLEARANCE
1. Install camshaft bracket and tighten bolts to the specified
torque.
2. Measure inner diameter of camshaft bearing.
Standard inner diameter:
#1 to #5 journals
28.000 - 28.025 mm (1.1024 - 1.1033 in)

5. Cut or grind valve seat using suitable tool to the specified
dimensions as shown in SDS.
6. After cutting, lap valve seat with abrasive compound.
7. Check valve seating condition.
Seat face angle ªaº:
45É15¢- 45É45¢deg.
Contacting width ªWº:
Intake
1.48 - 1.63 mm (0.0583 - 0.0642 in)
Exhaust
1.8 - 2.0 mm (0.071 - 0.079 in)
8. Use a depth gauge to measure the distance between the
mounting surface of the cylinder head spring seat and the
valve stem end. If the distance is shorter than specified,
repeat step 5 above to adjust it. If it is longer, replace the
valve seat with a new one.
Valve seat resurface limit ªLº:
Intake 42.02 - 42.52 mm (1.6543 - 1.6740 in)
Exhaust 42.03 - 42.53 mm (1.6547 - 1.6744 in)
VALVE DIMENSIONS
Check dimensions of each valve. For dimensions, refer to SDS
(EM-2049).
When valve head has been worn down to 0.5 mm (0.020 in) in
margin thickness, replace valve.
Grinding allowance for valve stem tip is 0.2 mm (0.008 in) or
less.
VALVE SPRING
Squareness
1. Measure dimension ªSº.
Out-of-square ªSº:
Less than 2.2 mm (0.087 in)
2. If it exceeds the limit, replace spring.
Pressure
Check valve spring pressure at specified spring height.
Pressure: N (kg, lb) at height mm (in)
Standard
418.0 (42.6, 93.9) at 29.17 (1.1484)
Limit
393.0 (40.1, 88.4) at 29.17 (1.1484)
If it exceeds the limit, replace spring.

CYLINDER BLOCK DISTORTION AND WEAR
1. Clean upper face of cylinder block.
Use a reliable straightedge and feeler gauge to check the
flatness of cylinder block surface. Check along six positions
shown in figure.
Limit:
0.1 mm (0.004 in)
2. If out of specification, resurface it.
The limit for cylinder block resurfacing is determined by cyl-
inder head resurfacing.
Amount of cylinder head resurfacing is ªAº
Amount of cylinder block resurfacing is ªBº
The maximum limit is as follows:
A+B=0.2mm(0.008 in)
Nominal cylinder block height
from crankshaft center:
246.95 - 247.05 mm (9.7224 - 9.7264 in)
3. If necessary, replace cylinder block.
PISTON-TO-BORE CLEARANCE
1. Using a bore gauge, measure cylinder bore for wear, out-of-
round and taper.
Standard inner diameter:
Refer to SDS, EM-2052.
Wear limit: 0.2 mm (0.008 in)
Out-of-round (X þ Y) standard: 0.015 mm (0.0006 in)
Taper (A þ B) standard: 0.010 mm (0.0004 in)
If it exceeds the limit, rebore all cylinders. Replace cylinder
block if necessary.
2. Check for scratches and seizure. If seizure is found, hone it.
lIf cylinder block and piston are replaced, match piston
grade with grade number on cylinder block upper sur-
face.
3. Measure piston skirt diameter.
Piston diameter ªAº:
Refer to SDS, EM-2054.
Measuring point ªaº (Distance from the top):
Approximately 48 mm (1.89 in)
4. Check that piston-to-bore clearance is within specification.
Piston-to-bore clearance ªBº:
0.020 - 0.040 mm (0.0008 - 0.0016 in)
5. Determine piston oversize according to amount of cylinder
wear.
Oversize pistons are available for service. Refer to SDS,
EM-2054.
