OIL JET / CHECK VALVE |
|
The inspection procedure for this
oil jet is the same as for the conventional oil
jet. |
CRANKSHAFT OIL CLEARANCE (PLASTIGAGE METHOD) |
| The crankshaft oil clearance can be
measured easily by using a plastigage, as follows. |
 |
1.Remove oil and grease and
any other foreign matters from crankshaft journal and
bearing
inner surface. 2.Install the crankshaft. 3.Cut the plastigage to the same length as the width of bearing and place it on journal in parallel with its axis. 4.Gently place the crankshaft bearing cap over it and tighten the bolts to the specified torque. 5.Remove the bolts and gently remove the crankshaft bearing cap. |
 |
6.Measure the width of the
smashed plastigage at its widest section by using a scale
printed
on the plastigage bag. Standard value: 0.020 - 0.038 mm Limit: 0.1 mm |
CYLINDER BLOCK |
 |
1.Using a straightedge and
thickness gauge, check the block top surface for warpage.
Make
sure that the surface is free from gasket chips and other
objects. Standard value: 0.05 mm Limit: 0.1 mm 2.If the distortion is excessive, replace the cylinder block. |
 |
3.Check cylinder walls for
scratches and size. If defects are evident, replace the
cylinder
block. 4.Using cylinder gauge, measure the cylinder bore, and cylindricity. If worn badly, replace the cylinder block. Measurement points are shown in illustration. Standard value:
Cylindricity 0.02 mm or less |
