CYLINDER SLEEVES REMOVAL
00087
The cylinder sleeves (Figure 1, Item 1) are the wet type. The bottom of the sleeve is sealed in the crankcase by
three O-rings (Figure 1, Item 2). A flange (Figure 1, Item 3) at the top of each sleeve fits into a counterbore in the
top of the crankcase and serves to position the sleeve correctly. In some engines, shims may be used between the
sleeve flange and crankcase counterbore to provide the correct cylinder sleeve protrusion. The wet type sleeve is
water cooled over its entire length.

piston and connecting rod assemblies in clean cloth.

crankcase (Figure 2, Item 3).
2. Remove shims (Figure 2, Item 2) (if equipped) from counterbore in top of crankcase.
