Crank Journal Bearing condition...

(1/3) > >>

Oz350Four:
I bought a basket case 75 CB400 four and am in the process of stripping it down for a rebuild.
I'm not one for doing things half arsed like the previous owner did but I don't want to have to spend any more money than necessary.
Anyway, I'm down to the point where Ive split the cases and would like folks opinion as to the crank journal bearings.
Can these bearing halves be reused or should I replace them.
So as to not drown the would be reader in pictures I've posted the lower ones so as to get feedback.

Nurse Julie:
Hi and welcome to the Forum.
They have pitting and scoring, I would change them if it were my engine. Also check the crank for damage / wear.

McCabe-Thiele (Ted):
I agree with Julie, they are similar to how mine are - when you are that far into the engine get them replaced.

royhall:
I would also say new shells required there.

Bryanj:
Dirty oil not changed often enough, yes change them and infortunately with that marking check the ends as well
