1.6.3 Cylinder Liner
DETROIT DIESEL 53
Install Cylinder Liner, Piston and Connecting Rod Assembly
After the piston and connecting rod assembly have been installed in the cylinder liner, install the entire assembly in the
engine as follows:
I.
Make sure the seal ring groove in the cylinder block is clean. Then install a new seal ring.
NOTE: The current cylinder block has an additional seal ring groove approximately
1/8" below the original top groove (Fig. 9). This groove will permit further use of the
cylinder block where corrosion or erosion of the upper seal ring groove has occurred.
The lower seal ring groove in the current cylinder block has been eliminated.
Reinstallation of the lower seal ring is not necessary in the former cylinder block.
2. Apply hydrogenated vegetable type shortening or
permanent type antifreeze to the inner surface of the
seal ring.
3. If any of the pistons and liners are already in the engine, use hold-down clamps (Fig. 7) to retain the liners in place
when the crankshaft is rotated.
4. Rotate the crankshaft until the connecting rod journal of the particular cylinder being worked on is at the bottom of its
travel. Wipe the journal clean and lubricate it with clean engine oil.
5. Install the upper bearing shell -- the one with a short oil groove at each parting line -- in the connecting rod. Lubricate
the bearing shell with clean engine oil.
6. Position the piston, rod and liner assembly in line with the block bore (Fig. 10) so the identification number on the
rod is facing the engine serial number side (In-line engine). Also align the matchmarks on the liner and the block. Then
slide the entire assembly into the block bore and seal ring, being careful not to damage the seal ring.
7. Push or pull the piston and connecting rod into the liner until the upper bearing shell is firmly seated on the
crankshaft journal.
8. Place the lower bearing shell -- the one with the continuous oil groove from one parting line to the other -- in the
connecting rod cap, with the tang on the bearing shell in the notch in the connecting rod bearing cap. Lubricate the
bearing shell with clean engine oil.
9. Install the bearing cap and the bearing shell on the connecting rod with the identification numbers on the cap and the
rod adjacent to each other. On the 3/8"- 24 bolts (In-line engines), tighten the nuts to 40-45 lb-ft torque.
10. Check the connecting rod side clearance. The clearance between the side of the rod and the crankshaft should be
.006" to .012 "with new parts on an In-line engine.
11. Install the remaining liner, piston and rod assemblies in the same manner. Use hold-down clamps to hold each liner
in place.
12. After all of the liners and pistons have been installed, remove the hold-down clamps.
13. Install new compression gaskets and water and oil seals as outlined in Section 1.2. Then install the cylinder head
and any other parts which were removed from the engine.
14. After the engine has been completely reassembled, refer to the Lubricating Oil Specifications in Section 13.3 and
refill the crankcase to the proper level on the dipstick.
15. Close all of the drains and fill the cooling system.
16. If new parts such as pistons, rings, cylinder liners or bearings were installed, operate the engine on the run-in
schedule given in Section 13.2.1.
