Detroit Diesel — Installation of Cylinder Liner
Installation
From a Detroit Diesel service manual — check it applies to your exact model before use.
Before you start
- The cylinder liner collar and collar seat must remain completely free of oil.
- Do not overtighten the installation tool; this may deform the cylinder liner and make the installation tool more difficult to remove.
- To prevent damage to the O-rings, the cylinder liner must be rotated during installation.
- If installing the old cylinder liner, offset the reference marks 90 degrees from the previous ones.
Procedure
- Perform Measurement of Cylinder Liner Protrusion procedure.
- Install new O-rings, clean and dry, in cylinder block.
- Install Liner Seat D-Ring with flat surface against liner; do not over-stretch.
- Install new seat insert, clean and dry, into block counterbore.
- Apply light coating of engine oil to lower part of cylinder liner from O-ring area to bevelled area.
- When installing new liner, ensure diameter tolerance code corresponds to piston code.
- Install cylinder liner using installation tool J-46168.
- Tighten installation tool just enough to hold it inside liner without turning.
- Insert liner into block until it contacts O-rings; continue inserting past O-rings, keeping tool turning until seated.
- Remove installation tool from cylinder liner.
- Measure cylinder liner protrusion from block per Table 4.
- Measure inside diameter of cylinder liner and check out-of-round at three locations 60 degrees apart.
- Compare measurements; if they differ by more than maximum admissible out-of-round, remove liner and inspect O-rings and seating area.
- Replace damaged O-rings; check out-of-round again until it meets specifications.
- Install piston. Refer to "Installation of Piston".
