Small bearing end of crank, 4age

[cosi]

There is this small bearing in the rear end of the my 4age bluetop crank. Its the one that you can see through the clutch/flywheel. Is this bearing necessary and what happens when it is not used? Do FWD cranks have it as well or is it just a RWD thing?

Thanks!!

it's a spigot bearing only rwd's have them as it helps hold the input shaft of the gearbox central and probly a couple other reasons that i don't know of

its only rwd thing for 4age, although I've seen it in b16a2...
