Grinding of crankshaft
CAUTION
• If the crankshaft pins and journals are ground to
undersizes, be sure to use bearings of corresponding
undersizes.
•
Do not change the center-to-center distance A between the jour-
nal and pin.
A:
57.5
mm
•
Do not change the journal width B and the pin width C.
B:
37
mm
C:
42
mm
•
Finish the fillets D smoothly.
D:
R4 ± 0.2 mm
•
Carry out a magnetic inspection to check for cracks possibly
caused by grinding. Also, check that the hardness of the surface
has not dropped below Shore hardness number (Hs) 75.
•
Replace the crankshaft if defects are evident.
Crankshaft undersize dimensions (Unit: mm)
•
When grinding, turn both the crankshaft and the grinder counter-
clockwise as viewed from the crankshaft front end.
•
When finishing the crankshaft with whetstone or sandpaper, ro-
tate the crankshaft clockwise.
Inspection: Distortion of crankcase top surface
•
If the measurement exceeds the limit, correct the crankcase top
surface with a surface grinder.
CAUTION
• Do not grind the crankcase top surface so much as to com-
promise the correct piston projection.
