3-50. CYLINDER LINERS AND CYLINDER BLOCK MAINTENANCE (Contd)
17.
Install cylinder liner (2) in cylinder block (1).
18.
Install clamps (5) on cylinder block (1) with two washers (4) and cylinder head screws (3). Tighten
cylinder head screws (3) 50 lb-ft (68
19.
Measure clearance between lower cylinder liner (2) and cylinder block (1) with feeler gage.
Clearance should be 0.002-0.006 in. (0.051-0.152 mm). If clearance exceeds limits, remove cylinder
liner (2) and replace cylinder block (1) or notify your supervisor for machining.
20.
Remove two cylinder head screws (3), washers (4), and clamps (5) from cylinder block (1).
21.
Remove cylinder liner (2) from cylinder block (1).
22.
Using telescoping gage, measure lower inside diameter of cylinder liner (2). Inside diameter should
be 6.124-6.126 in. (155.55-155.60 mm). If inside diameter is not within limits, replace cylinder
block (1) or notify your supervisor for machining.
23.
Install main bearing caps (6) on cylinder block (1) without crankshaft or bearing shells (para. 3-48).
24.
Using telescoping gage, measure inside diameter of main bearing bore (7) horizontally, vertically,
and diagonally. Main bearing bore (7) diameter should not exceed 4.75 in. (120.65 mm).
25.
If main bearing bore (7) diameter exceeds 4.75 in. (120.65 mm), replace main bearing cap (6) and
remeasure inside diameter of main bearing bore (7). If measurement still exceeds 4.75 in.
(120.65 mm), replace cylinder block (1).
26.
Remove main bearing caps (6) from cylinder block (1) (para. 3-48).
