1.6.3 Cylinder Liner
DETROIT DIESEL 53
Remove Cylinder Liner
It is very important that the proper method is followed when removing a cylinder liner. Do not attempt to push the liner
out by inserting a bar in the liner ports and rotating the crankshaft, otherwise the piston may be damaged or the upper
ring groove may collapse.
To remove a cylinder liner, refer to Fig. 2 and proceed as follows:
1. Remove the piston and connecting rod assembly as outlined in Section 1.6.
2. Remove the cylinder liner with tool set J 22490 as follows:
a. Slip the lower puller clamp up on the puller rod and off the tapered seat. Cock the clamp so it will slide down
through the liner. The clamp will drop back on the tapered seat after it clears the bottom of the liner. Then slide
the upper puller clamp down against the top edge of the liner.

b. With the tool in place, strike the upset head on the upper end of the puller rod a sharp blow with the puller weight,
thus releasing the liner.
c. Remove the tool from the liner Then remove the liner from the cylinder block.
d. Remove and discard the cylinder liner seal ring from the groove in the cylinder block bore. If tool J 22490 is
unavailable, tap the liner out with a hardwood block and hammer.
Inspect Used Cylinder Liner
When the cylinder liner is removed from the cylinder block, it must be thoroughly cleaned and then checked for:
Cracks
Scoring
Poor contact on outer surface
Flange irregularities
Inside diameter
Out-of-round
Taper
A cracked or excessively scored liner must be discarded. A slightly scored liner may be cleaned-up and re-used.
Excessive liner-to-block clearance or block bore distortion will reduce heat transfer from the liner to the block and to the
engine coolant. Poor contact between the liner and the block bore may be indicated by stains or low pressure areas on
the outer surface of the liner.
Examine the outside diameter of the liner for fretting.
