Main bearings question

[demon9374]

Are these ok to use still?

The size/number are the same, but after checking, I've realised the new ones (all 9 bearings to do the bottom end are the same) don't have rail type things like the old bearings have..

This is a picture of new/old, the old main bearing is on the right, it has some sort of rail type thing, all of which my new bearings don't.

Pattern parts often differ in looks to an original part. They are often cheaper because they are manufactured in a cheaper way. As long as the replacement part is specified to do the job you will be OK.

yes they look fine, the differance is that the old ones have a plastic rail and the new ones have a steel one . should be fine
