Cylinder Sleeve Removal
NOTE: Before installing the puller, bar the engine over
so the crankshaft journal is located at the bottom (low
point) of its travel. This prevents possible damage
to the journal by the puller lifting jaws during puller
installation.
NOTE: When you remove the sleeve from puller,
mark the sleeve with its cylinder bore number. Also
mark the sleeve position in the engine block for the
purposes of inspection and assembly.
1. Position the cylinder sleeve puller in the sleeve
and spread the lifting jaws so the tangs grip the
bottom of the sleeve (Figure 309).
