DETROIT DIESEL 53
Cylinder Block 1.1
were used in engines beginning with serial numbers 2D-4010, 3D-117 and 4D-348.
New service replacement cylinder block assemblies include the main bearing caps, bolts and washers and the camshaft
bearings (bushings). The dowels and the necessary plugs are also included.
Since the cylinder block is the main structural part of the engine, the various sub-assemblies must be removed from
the cylinder block when an engine is overhauled.
The hydraulically operated overhaul stand (Fig. 9) provides a convenient support when stripping a cylinder block. The
engine is mounted in an upright position. It may then be tipped on its side, rotated in either direction 90° or 180° where it
is locked in place and then, if desired, tipped back with either end or the oil pan side up.

following steps will be necessary:
Drain the cooling system.
Drain the lubricating oil.
Disconnect the fuel lines.
Remove the air silencer or air cleaner and mounting bracket.
Remove the turbocharger, if used.
Remove the blower on In-Line engines.
Disconnect the exhaust piping and remove the exhaust manifold(s).
Disconnect the throttle controls.
Disconnect and remove the starting motor, battery-charging generator and other electrical equipment.
