b. Label parts for assembly and remove the main beari ng cap from the cylinder block while tapping lightly
with a plastic hammer.
CAUTION:
Identify installation positions, and store th em without mixing up.
9. Remove crankshaft (2). CAUTION:
• Be careful not damage or deform signal plate (1) mounted on crankshaft.
• When setting crankshaft on a flat floor surface, use a
block of wood to avoid inte rference between signal plate
and the floor surface.
• Never remove signal plate unl ess it is necessary to do so.
NOTE:
When removing or installing signal plate, use TORX socket (size
T40).
10. Pull rear oil seal out from rear end of crankshaft.
11. Label parts for assembly and remove main bearing (upper and lower) and thrust bearings from cylinder block and main bearing cap.
