Using universal cylinder sleeve puller, remove cylinder sleeve (1) from cylinder block (11).
NOTE
If shims are used under cylinder sleeve, do not discard shims.
Using a micrometer or equivalent, measure and record
thickness of six shims and tag the location of each cylinder
sleeve and shims to aid in assembly.
2.
Remove red O-ring (4), black O-ring (5), gasket (3) and shims (2) from cylinder sleeve (1). Discard
red O-ring (4), black O-ring (5), and gasket (3).

5.505 in. (13.983 cm).
7.
Inspect all cylinder block (11) plug holes and threaded holes for damaged threads and surfaces.
8.
Inspect all dowel pins (8) and (12) for cracks or distortion.
9.
Using straightedge and 0.02 in. (0.51 mm) feeler gauge, check cylinder block (11) for flatness. If
gap between straightedge and cylinder block (10) is more than 0.02 in. (0.51 mm), cylinder block
(11) must be milled.
