REMOVAL CONTINUED
NOTE
If crankshaft is to be removed, disregard step 6.
An alternate method of removing upper halves of bearings is to hammer closed end of a
small cotter pin to form a T and then insert prongs of cotter pin in oil hole of crankshaft
journal with flattened head just protruding. Rotate crankshaft, and cotter pin head will
push bearing from position.
6. Use a thin piece of flexible soft metal to remove seven upper bearing halves (Figure 3, Item 1) from between
crankshaft (Figure 3, Item 3) and crankcase (Figure 3, Item 4). This will push against end of bearing farthest
from nib (Figure 3, Item 2) holding bearing in crankcase support and at same time turning crankshaft in direc-
tion of rotation. Bearing will slide easily from position.
