CONROD DEFLECTION INSPECTION
• Move the small end sideways while holding the big end
immovable in thrust direction.
• Measure the amount of deflection.
• Turn the conrod and see if it moves smoothly without play and
noise.
• This method can check the extent of wear on the parts of the
conrod’s big end.
% Conrod deflection:
Service Limit: 3.0 mm
$ 09900-20607: Dial gauge (1/100 mm)
09900-20701: Magnetic stand
09900-21304: V-block (100 mm)
CRANKSHAFT RUNOUT INSPECTION
• With the right and left crank journals supported with V-block,
turn the crankshaft slowly. At this time, measure the crank-
shaft end runout using a dial gauge. If the runout exceeds the
service limit, replace the crankshaft.
% Crankshaft runout:
Service Limit: 0.10 mm
$ 09900-20607: Dial gauge (1/100 mm)
09900-20701: Magnetic stand
09900-21304: V-block (100 mm)
NOTE:
Set the V-blocks so that the crankshaft becomes horizontal.
