InspectionNLEM0073CRANKSHAFT END PLAYNLEM0073S13+Measure the moving distance of the crankshaft with the dial
gauge when the crankshaft is moved fully forward or back-
ward.
Standard: 0.10 - 0.25 mm (0.0039 - 0.0098 in)
Limit: 0.30 mm (0.0118 in)
+If the value exceeds the limit, replace thrust bearings with new
ones and measure again. If the measurement exceeds the limit
again, replace crankshaft with a new one.

When re-using a removed cylinder block:
+Measure the inner diameter of the cylinder block bore.
+Determine the bore grade by comparing the measurement with
the values under ªCylinder bore IDº of the table below. Choose
a piston of the same grade.
Selective fitting for piston:
Unit: mm (in)
Grade (punched) 1 2 3

(3.3835 - 3.3839)
5. Determine piston oversize according to amount of cylinder
wear.
+For oversize pistons, 0.25 and 0.5OS [0.25 mm (0.0098 in),
0.5 mm (0.0197 in) oversize] are available as service parts.
Refer to SDS, EM-248. When using an oversize piston,
hone cylinder so that the clearance between piston and
cylinder becomes the specified value. Be sure to use
appropriate oversize piston ring for the oversize piston.
6. Cylinder bore size is determined by adding piston-to-bore
clearance to piston diameter ªAº.
Rebored size calculation: D = A+BþC
where,
D: Bored diameter
A: Piston diameter as measured
B: Piston-to-bore clearance
C: Honing allowance 0.02 mm (0.0008 in)
7. Cut cylinder bores.
+When any cylinder needs boring, all other cylinders must
also be bored.
+Do not cut too much out of cylinder bore at a time. Cut
only 0.05 mm (0.0020 in) or so in diameter at a time.
8. Hone cylinders to obtain specified piston-to-bore clearance.
9. Measure finished cylinder bore for out-of-round and taper.
+Measurement should be done after cylinder bore cools
down.

rear side of the piston.
+Install securely to fully fit into the groove.
2. Install piston to the connecting rod.
+Heat the piston with an industrial drier to 60 to 70ÉC (140 to
158ÉF) so that the piston pin can be easily inserted by finger.
Then, insert the piston pin from the front of the piston into the
piston and into the connecting rod.

+Assemble so that the front mark on the piston top surface and
cylinder No. stamped on connecting rod are positioned as
shown in the figure.
3. Install snap ring on piston front.
+Refer to step 1. above for notes for installation.
+After installing, check that the connecting rod moves smoothly.
4. Install piston rings using piston ring expander (Commercial
Service Tool).
+Be extremely careful to avoid any damage to the piston.
