CYLINDER BLOCK MAINTENANCE (Contd)
REMOVAL
CAUTION
Do not allow expansion plugs to be driven into block. If expansion
plug will not pivot in opening, it may be necessary to drill a small
hole in expansion plug and use a slide hammer to pull expansion
plug from cylinder block. Failure to comply may result in damage to
equipment.
Do not allow metal shavings to fall into engine when drilling a hole
in expansion plug. Failure to comply may result in damage to
equipment.
1.
Using center punch, drive in one corner of expansion plug (4) so expansion plug (4) will pivot in
opening. Pull expansion plug (4) from cylinder block (6). Repeat this step to remove remaining four
expansion plugs (4) from cylinder block (6). Discard expansion plugs (4).
2.
Using center punch, drive in one corner of expansion plug (9) so expansion plug (9) will pivot in
opening. Pull expansion plug (9) from cylinder block (6). Repeat this step to remove remaining three
expansion plugs (9) from cylinder block (6). Discard expansion plugs (9).
3.
Using center punch, drive in one corner of expansion plug (7) so expansion plug (7) will pivot in
opening. Pull expansion plug (7) from cylinder block (6). Repeat this step to remove remaining two
new expansion plugs (7) from cylinder block (6). Discard new expansion plugs (7).
4.
Using center punch, drive in one corner of expansion plug (17) so expansion plug (17) will pivot in
opening. Pull expansion plug (17) from cylinder block (6). Repeat this step to remove remaining two
new expansion plugs (17) from cylinder block (6). Discard new expansion plugs (17).
5.
Using center punch, drive in one corner of expansion plug (8) so expansion plug (8) will pivot in
opening. Pull expansion plug (8) from cylinder block (6). Repeat this step to remove remaining new
expansion plugs (1) and (16) from cylinder block (6). Discard new expansion plugs (1), (8), and (16).
6.
Remove three threaded plugs (15) from cam side of cylinder block (6).
7.
Remove threaded plug (11) from cam side of cylinder block (6).
8.
Remove pipe plugs (5) and (2) from cylinder block (6).
9.
Remove screw (14), plug (13), and O-ring (12) from cylinder block (6). Discard O-ring (12).
10.
If damaged, remove two dowel pins (19) from front of cylinder block (6).
11.
If damaged, remove six piston cooling nozzles (18) from underside of cylinder block (6).
12.
If damaged, remove two dowel rings (3) from top of cylinder block (6).
13.
If damaged, remove fourteen dowel rings (10) from underside of cylinder block (6) and two dowel
rings (10) from rear end of cylinder block (6).
