40mm rod bearings question
Posted: Sun Oct 10, 2021 8:31 am
I'm posting this here because it's something relating to the 4A-FE and the early 4A-GE. Both gens of 4A-FE rods and of course early bigport GE rods have 40mm big ends. But the bearing part numbers are different. Any ideas why that is?
Mark 1 bearings used as examples.
4A-FE:
13041-15030-01 (superseded by 13041-15031-01)
4A-GE:
13041-16040-01
Is it something about the GE bearings being for higher RPM / "race use?" Are the rod IDs slightly different? Rod widths are different?
