Removal (Aluminum Cylinder Engines).

To remove the crankshaft from aluminum alloy engines, remove rust or

burrs from the power take-off end of the crankshaft. Remove crankcase

cover or sump. If sump or cover sticks, tap lightly on alternate sides

near dowel. Turn crankshaft to align the crankshaft and camgear timing

marks, lift out the camgear, then remove the crankshaft. On the SX-1086

model, the crankshaft and camgear must be removed together.

5.2.2.8.2

Checking Crankshaft.

Table No. 10 shows the rejection sizes of the various wear points of the

crankshaft. Discard crankshaft if worn smaller than the size shown. Key-

ways should be checked to be sure they are not worn or spread. Remove

burrs from keyway edges to prevent scratching the bearing.
