CRANKSHAFT AND CRANKCASE INSPECTION
• Replace the whole set of the crankshaft if serious wear is found while inspecting. Measur
e
the
axial trend clearance of the big end of the connecting rod.
• When measuring, put the large end of the connecting rod close to the crank, and insert the feeler
gauge between the other side and the crank, for the correct end play.
Service Limit
0.55mm
• Measure the radial trend (X,Y) clearance of the big end of the connecting rod.
Service Limit
0.05mm
• Measure the main shaft journal jump of the crankshaft.
If
this measurement is too great, it will cause the engine to shake abnormally, shortening the
life o
f the engine
It
must be examined carefully when inspecting.
Service Limit
0.10mm(A=90)
0.10mm(B=105)
• Examine if there is any loose, or unusual sound when the crank journal bearing turn
s. If
there is,
the whole set should be changed.
• After cleaning the crankcase, inspect
to see
if there is any damage.
• Inspect
whether
the joint face of the crankcase is smooth and clean
. While reassembling, notice
if it
will affect the sealing performance between the left and right crankcase.

refinish
it.
If damage is too severe, replace the cover.
CRANKSHAFT AND CRANKCASE INSTALLATION
• Mount the crankcase oil seal.
• Put the cam chain into the left crankcase.
• Put the crankshaft into the left crankcase.
Because the right and left crankcase axle hole must be concentric, they
should be replaced at the same time.
Pay attention to avoid damaging the oil seal with the cam chain.
