- Check ring end gaps in the bore before installation and stagger the gaps.
- Bearings: Rod and main bearings are usually replaced at the same time.
- Gasket set: The engine comes apart for this job.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
