Remove components in order of numbers and reinstall in reverse sequence.
For cleaning work:
With starter removed, clean with bearing flange facing down - i.e. hanging
so that no moisture can penetrate the magnetic switch.
With starter installed, do not clean with direct water jet.
Penetrating moisture leads to corrosion and interrupted contact of magnetic switch.
Check starter ring gear for wear.
