ENGINE 3-45
PISTON RING END GAP
Fit the piston ring squarely into the cylinder and measure the
piston ring end gap using the thickness gauge.
If any of the measurements exceeds the service limit, replace
the piston ring with a new one.
&
Piston ring end gap:
Service Limit:
1st: 0.50 mm (0.020 in)
2nd: 0.50 mm (0.020 in)
%
09900-20803: Thickness gauge
CONROD
CONROD SMALL END I.D.
Using a small bore gauge, measure the inside diameter of the
conrod small end. If the inside diameter of the conrod small end
exceeds the limit, replace the conrod.
&
Conrod small end I.D.:
Service Limit: 20.040 mm ( 0.7889 in)
%
09900-20602: Dial gauge (1/1 000 mm, 1 mm)
09900-22403: Small bore gauge (18 – 35 mm)
CONROD DEFLECTION AND BIG END SIDE CLEARANCE
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
be used to check the extent of wear on the parts of the conrod
big end.
&
Conrod deflection
Service Limit: 3.0 mm (0.12 in)
%
09900-20701: Magnetic stand
09900-20607: Dial gauge (1/100 mm)
09900-21304: V-block set (100 mm)
Push the big end of the conrod to one side and measure the
side clearance using a thickness gauge. If the clearance
exceeds the service limit, replace the crankshaft assembly with
a new one or bring the deflection and the side clearance within
the service limit by replacing the worn parts (conrod, big end
bearing, crank pin, etc.) with new ones.
&
Conrod big end side clearance
Service Limit: 1.0 mm (0.039 in)
