Conrod and Crankshaft Inspection
B827H11406035
Refer to “Engine Bottom Side Disassembly (Page 1D-
34)”.
Conrod Small End I.D.
Measure the conrod small end inside diameter with the
dial calipers.
If conrod small end inside diameter exceeds the service
limit, replace the conrod.
Special tool
(A): 09900–20605 (Dial calipers (1/100 mm, 10 –
34 mm))
Conrod small end I.D.
Service limit: 20.040 mm (0.7890 in)
Conrod Deflection
Wear On the big end of the conrod can be estimated by
checking the movement of the small end of the rod. This
method can also check the extent of ware on the parts of
the conrod’s big end.
Special tool
(A): 09900–20701 (Magnetic stand)
(B): 09900–20607 (Dial gauge (1/100 mm, 10
mm))
(C): 09900–21304 (V-block (100 mm))
Conrod deflection
Service Limit: 3.0 mm (0.12 in)
Conrod Big End Side Clearance
1) Check the conrod big end side clearance with the
thickness gauge.
Special tool
(A): 09900–20803 (Thickness gauge)
Conrod big end side clearance
Service limit: 1.0 mm (0.04 in)
2) If the clearance exceeds the limit, replace the
crankshaft assembly and conrod with a new one.
Crankshaft Runout
• Measure the crankshaft runout with V-blocks and dial
gauge.
NOTE
• Place the crankshaft onto the V-blocks so
that it becomes horizontally.
• Measure the runout from the tips of the
crankshaft.
Crankshaft runout
Service limit: 0.08 mm (0.003 in)
Special tool
(A): 09900–20607 (Dial gauge (1/100 mm, 10
mm))
: 09900–20701 (Magnetic stand)
